Tool Modifications 2.0 – The 8 Pound Force Axe – By: Shane Klug

4 comments

February 2011, I transferred to a ladder company, my first time being assigned to a truck.  Detroit ladder trucks typically have 6-pound pick head axes and 8-pound sledge hammers on them.  I tried both of them on the roof, and my tool of choice became the 6-pound pick head axe. I managed to get my hands on an 8-pound pick head axe and gave that a try. While the extra weight was great for smashing through roofs, the balance was VERY nose heavy, which made it harder to control and also very uncomfortable to carry.  Over the summer I was able to attend the Brotherhood Instructors Forcible Entry Ops class held in Independence Twp Michigan, where I used an 8-pound flathead axe, specifically the fire hooks unlimited 8-pound force axe.  I really liked the way the axe was balanced.  It was easy to control when swinging (in the forcible entry class) and seemed easy to carry.  Sometime after the class I purchased my own to use at work.  I decided to make some modifications, but with a twist, compared to what I had seen in the Brotherhood Instructor class.  First, I wanted to try and put the “notch” that allows the halligan forks to marry with the axe in a location that put both tool handles together, so I could get my hand around both tools. In Detroit, most front door forcible entry is performed by engine companies, so for me, I won’t be carrying a halligan much. So the more important modification I wanted was some kind of overstrike protection for my axe, as it would be used mainly for venting the peak roof of single family dwellings.  I had seen small sections of angle iron welded on the bottom of the axe head on the axes used in Gary Fire Dept (Gary, IN).  But they were welded with some space between the angle irons and the handle itself. In my opinion, this location for the over strike protection made it very difficult to carry the axe, especially while climbing up ladders etc.  So I had a friend TIG weld on some sections of angle iron below the head of the axe, but positioned them right against the handle of the axe, following the axe handle contour.  For those of you who have used an axe on a roof to smash a vent hole, you know that often times the axe head will smash through the roof deck and stop on the handle itself, over time break the axe handle right below the axe head itself.  Hopefully this modification will add some life to the tool for me.

 

I know this axe is called an 8-pound force axe, but I think the name sells this tool short.  As I mentioned above, I don’t do the majority of forcible entry, as the engine companies often do the front door and Detroit truck companies only carry one halligan, which is mainly carried by the boss of the truck.  My main objective as a deckie on the back end is to make the roof and ventilate. The vast majority of the time, I’m using this axe to open single family dwelling roofs.  When used in tandem with a saw (chain or rotary), I can use the flat side of the axe to “turn” the boards over on the rafters after they have been cut.  Of if there is no saw available (or the roof doesn’t lend itself to using a saw), I can use the blade side of the axe to start a hole (especially on roof decks that have multiple layers of shingles), then can flip over to continue smashing the roof boards.

       All in all, this axe is fantastic for forcible entry and makes a great tool for vertical ventilation. With the addition of the over strike protection, hopefully the tool will have a long service life opening roofs!

Changing Saw Blades – Diamonds are a Firemen’s best friend too – By Grant Light

No comments

 

Over the past few years there have been some big changes in the type of circular saw blades used by fire departments across the country.  In the past almost all of the metal and concrete cutting was accomplished with fiber wheels made of a sacrificial material such as aluminum oxide or silicon carbide.  The biggest problem with these blades was that they got smaller as you cut, causing you to change blades during a rescue and at times not allowing you the depth of cut needed to get the job done.  The potential for blades to fly apart during operations was also a big safety issue.  You had one blade for metal, one for concrete and at times one for stone.  Just that fact alone required a quick decision about the work to be done and in some instances quick blade changes were required before cutting could begin.

Just like everything else in the fire service, saw blades have changed dramatically as new technologies have moved from the construction industry to the rescue services.  Diamonds are where that technology has taken us.  Many different types of diamond blades are available but we will look at two, Segmented and Vacuum Braised.  Segmented blades have a diamond impregnated segment attached to a steel wheel.  They were originally designed for cutting concrete with imbedded rebar.  They moved to the fire service through US&R teams and are used by many companies to cut metal during forcible entry operations.

The newest additions to diamond technology are the Vacuum Braised blades.  They have very high quality diamonds attached directly to the steel wheel.  This removes any chance of a diamond segment coming off the wheel and becoming a projectile during operations.  These blades can cut an extremely wide range of products such as Hardened locks & shackles, hockey puck locks, security gates, re-bar, chain-link fence, stucco, concrete, block, brick, stone, asphalt, wood, drywall, car doors, ductile iron, cast iron, angle iron, black iron, schedule 40 &80 steel pipe, plastic pipe, 2x4s and plywood.  These blades will do all this without reducing the depth of cut and outlasting fiber wheels 100:1 or more.  During training at a scrap yard we cut through a fiberglass roof on a conversion van, which was backed up by 4 layers of OSB plywood and then turned and cut the class 3-trailer hitch off the rear of the vehicle.   We were using a Desert Diamond vacuum braised blade and it didn’t skip a beat.  The ability to grab a circular saw and cut just about anything you encounter is a welcome change from the blades we used just a few years ago.  These new blades have a higher upfront cost but their ability to cut a wide range of materials, remain a constant diameter and outlast any forcible entry cutting scenario you might encounter make them a smart choice as you move forward into the future of circular saw blades.

Checking for Extension

No comments

Firefighters assigned to the roof play a critical role in numerous fire ground tasks.  Vertical ventilation, building information, and checking for fire extension to the cockloft or attic space are just a few of these tasks.  Vertical ventilation and checking for extension can often be done together by taking a skylight and opening the skylight returns.  Click here to see our previous video on that topic.  When the roof is pitched or there is a void space along the parapet fire can easily extend through these spaces. 

Many times the roof is pitched downwards from the front of the building to the rear in order to allow drainage at the back of the building.  If there is a fire in the rear of the building and the roof is pitched downward from front to rear an inspection hole should be made towards the front of the building.  Throughout the operation monitor this inspection hole for heat, smoke, and fire.  If fire extension is found or expected, enlarge the opening and radio the findings to your company officer or incident commander.  This further illustrates the importance of checking for fire in the cockloft immediately inside the entrance of a commercial building if no one is assigned to the roof.

Roof void spaces are a common path of fire travel.  Firefighters assigned to the roof should place inspection cuts in void areas if there is any suspicion of fire in the cockloft or voids.  Triangular void spaces along the parapet are very common in residential and commercial buildings.  Usually these void spaces conceal structural members used to support the parapet.  If fire is found in this area be sure that no one is on the sidewalk below the parapet.  Here are a few pictures of this construction feature courtesy of Keith Morse from the Woodland Twp. NJ Fire Dept.

Tactical Discussion: Apartment Fire w/ Critical Decisions by: Nate DeMarse

8 comments

We first saw this video on Backstep Firefighter. An excellent video surfaced this week that addresses some very critical decisions that must be made in seconds at this early arriving apartment fire in downtown Mamaroneck, New York.  I want to preface this discussion by saying that the Fire Department in Mamaroneck did an OUTSTANDING job in getting several things accomplished simultaneously with very limited manpower. They were confronted with a very complex situation, including a complex laddering problem that they overcame without hesitation.

It appears that the first due engine has arrived to a heavy fire condition in at least one room on the second floor of a three story apartments over stores "downtown-type" building that is common across the entire North American region. In reality, this fire could have happened in nearly ANY TOWN in North America. So since it COULD HAPPEN in your town, here are a few questions to discuss the incident.

There is a visible victim at the top floor window in obvious distress. As we say at every Brotherhood Instructors, LLC course, I am going to step out of my "FDNY Manpower Fantasy World" and attempt to stir a discussion that applies to the other 95% of the firefighting world.  You are arriving with an "now-standard" engine staffed with THREE (including the boss). If you have a total of four, you are extremely lucky, and feel free to answer accordingly. The next due engine and/or truck is 4-5 minutes out.  How and when are we addressing the following concerns from the video:

1) Do we stretch the line to confine/extinguish the fire first or do we go for the ladder rescue? Why? What are the pros and cons of each?

2) Can you split your company to get both accomplished at once? If so how? What are the implications?

3) What sized portable ladder (if it was available on your engine) would you use to reach the 3rd floor sill?

4) What are other options to the portable ladder in the front?

5) What size attack line are you pulling to attack this second floor fire?

6) What are the forcible entry concerns at this fire? Type of door, locks, etc…?

Please copy and paste the questions into your reply below, and answer using your name & department. Keep in mind that we have a lot of young firefighters on this blog that read our posts  to learn, so if you have something throw it down even if you think it is very basic. To the young guys: DON'T BE AFRAID TO ASK QUESTIONS!

Now take a look at the photos below (bing.com, birds-eye-view) for some added size-up discussion. Unless you were intimately familiar with this building during inspections, EMS runs, water leaks, etc… this building can cause you some complex problems.

1) The fire is located on the 2nd floor, but the 3rd floor is only about 1/2 or 3/4 the depth of the building. Does this now become a top floor fire? How are you getting to the lower level (2nd floor roof) in the rear? How would you communicate this?

As a Roof Firefighter, in my opinion your game plan has now changed. I would be expecting to go up there and force a skylight, scuttle and/or bulkhead and do a perimeter survey. This won't be the case at this job. This is a perfect scenario to drive the point home of crawling or probing with a tool in front of you in a limited visibility condition. If you do not in this case, you can take a 1 story fall to the rear roof, rendering you injured or worse.

2) Note the potential VES opportunity that may be available on the Exposure 2(B) roof. It appears from the overview photo that the window in the A-B (1-2) corner may lead to the same room that the victim is trapped. There are also similar VES opportunities in the rear (2nd floor roof) if needed.

Feel free to add further questions or stir discussion. Remember, we strictly moderate our blog discussions. Keep it professional and to sign your posts. NO UNSIGNED POSTS or posts that simply bash the department (which would be very hard in this case) will be allowed.  Stay safe!

 

 

 

Covered Skylights – By: Chris Collier

2 comments

We have done numerous articles about skylights, here is another.  These building features can be an asset to firefighters assigned to the roof as a means for quick ventilation.  Their location, many times above the interior stairs, makes them an ideal vertical ventilation location.  Relieving the interior stairs of smoke will help civilians evacuate, possibly increase visibility for the forcible entry team, and allow the engine to stretch to the proper location a little easier. 

Conversely, skylights can be dangerous to an unknowing firefighter, especially on a smokey roof.  Leaking skylights are many times replaced by removing the skylight and roofing over the area that was once the skylight.  If you are lucky this area of the roof will be raised and it will be obvious that this situation exists.  If not, the skylight can be covered over flush with the rest of the roof, increasing the danger. 

The quality of this patch job is where our concern lies.  If this area is properly framed out, covered with plywood, and then roofed over we are in pretty good shape.  Often these openings are covered with only a thin piece of plywood with no framing underneath and then covered with roofing material.  As you can see in this photo the once skylight has been framed out with 2×4" and then covered with plywood and rolled roofing. 

A few roof safety tips:

  • Be cautious of any area that appears to have been patched

Any patched area can be hazardous, not only roofed over skylights.  Patches normally indicate an area that was leaking.  The roof surface has been repaired to stop the leak but the water damage to the structural components beneath can not be seen. 

  • Avoid walking across roofed over skylights
  • If you can't see, crawl
  • Cross from building to building in the front

Power Saw Decompression Valves – By: Andrew Brassard

2 comments

There are a tremendous amount of myths and misconceptions that circle in the fire service about the decompression valve on rotary saws.  Some of these myths and misconceptions can lead to a lack of saw performance and or and inability to put the saw into action when it is needed most.

What is a Decompression Valve?

Basically, the way that a decompression valve works is that it is a small one way valve that is bored into the saws combustion chamber. When the starter cord is pulled the recoil turns causing the piston to raise causing compression to build inside the cylinder.  This compression can make the saw hard to start due to the resistance of the compression on the saws recoil. The valve allows a bit of the compression to escape, this in turn allows for the saw to start easier. The valve is semi-automatic meaning that it must be depressed by the saw operator before starting, after the saw fires the decompression valve automatically closes.

The Myths and Misconceptions

One of the biggest myths and misconceptions about the decompression valve is whether or not it needs to be depressed every time you pull the starter cord or not.  The answer is absolutely YES!  Now the reason for this is not necessarily to make it easier for the saw operator because lets be honest, if you can’t pull the cord without pushing in the decompression valve because it is too hard…. Than riding around on a fire truck is probably not for you!  There are two reasons that you want to ensure that the decompression valve has been depressed every time:

  1. The first reason is that starting the saw without the decompression valve engaged is tremendously hard on the saws starter recoil, this can lead to the starter cord breaking during start up or the cord starting to become loose and it will tend to hang out of the recoil.
  2. The second reason is that if the saw is constantly turned over it is generating tremendous amounts of compression inside the compression chamber, that compression is constantly pushed into the closed valve. What will start to happen is the valve will wear down and start to leak compression all the time. This leak in the compression can cause serious performance issues with your saw, if you find that your saw is bogging down a lot during roof or forcible entry operations then this could be an issue with the compression of your saw.

Another myth and misconception about decompression valves is that regular maintenance is not required.  The decompression valve just like any other part of the saw requires maintenance to run in tip top shape.  It tends to be a part of the regular service of the saws that is often overlooked, forgotten, or completely ignored. Much like a spark plug the end of the decompression valve is inside the combustion chamber of the engine.  Carbon, oil, and other unburned material tend to collect on the end of the valve.  This collection of unburned carbon can cause problems in the valve opening and closing or in the seal of the valve; this valve not closing properly can leave the pathway open for the compression to constantly leak.  Again a leak due to an improper seal or a malfunction in the valve will greatly effect the saws performance.

Maintenance

Maintenance on the decompression valve should be done annually or when ever the spark plug is being changed. The best practice for the cleaning of the valve is to first clean the dust and debris from the general area of the valve.  The reason for this is you don’t want any of dirt or debris getting into the cylinder. Once the area has been cleaned the valve can be removed with a wrench, and a clean rag can be placed into the hole to prevent any dust, dirt, or debris from getting into the cylinder.  After the valve has been removed it can be soaked in gasoline or WD-40 to remove the oils and unburned carbon. Once the valve has been cleaned in can be reinstalled.

During a fire ground operation, the decompression valve not being pressed won’t ruin your saw. It is extremely important to ensure that the valve is engaged during normal daily checks and training. This will build good habits that will no doubt carry over to the fire ground.

These are a couple of small tips that can make a ton of difference with your saws on the fire ground. Saws are a mechanical piece of equipment and they need to be cared for, inspected, and maintained if you want them to run in top form.

 

 

Building Construction Features – Cornices, By: Andrew Brassard

1 comment

I am sure if you talk to most fire service professionals about an area of basic knowledge that is lacking in today’s fire service it won’t take long to hear the topic of building construction surface.  Knowledge of building construction and how a fire reacts in that building is an area that is extremely under taught and misunderstood by today’s fire service.  It amazes me that we teach safety officers to spot a gloveless hand at 100 yards but we spend very little time talking about the hazards of balloon frame buildings, knee walls, fire spread issues, ordinary construction, etc.  With the changes in building construction nowadays and more and more emphasis of our training time on everything not fire related (ie. EMS, underwater HAZMAT, etc.) we need to teach building construction even more today than we ever have had to in previous years.

A cornice in architectural terms that describes a horizontal decorative molding that usually is found at the tops of doorways or building, for the purposes of the article we are going to look at them on the tops of flat roof buildings.

In the 19th and early 20th century, cornices were a very common place and most buildings were not complete without decorative cornice work adorning the top of the structure.  The functionality of the cornice was simple, to deflect and cause rain water to run off of the building and keep the water from running down the side of the brick work.  The intent was to save the brick work from the wear and tear of mother nature, essentially these decorative moldings were flat roofed buildings example of gutters or eves troughs.

Cornices came to favor in the 19th and 20th century but are in fact much older that that and have there roots all the way back to Roman times. Cornices as we know them in North America come in many different styles but the two most common types are wood and brick.  It is important to note the building construction material used in these cornices before it is too late; brick cornices will hold up much better than there wood counterparts to weather and fire deterioration.  Wood cornices are the more dangerous of the two types of cornices and for the purpose of this article we will talk about the hazards associated with only wood cornices.  Wooden cornices are generally not attached very well to the buildings facade, typically they have been nailed in when the building was first built and very little maintenance or thought goes into them until there is a problem.  Wooden cornices have been known to fall off buildings under snow loads and because of natural breakdown and deterioration of the wood and nails holding the cornice to the building.  When cornices start to become problematic for firefighters is during roof operations and if fire showing from windows starts to involve the cornices.

Roof Operations

When engaged in flat roof operations at one of these older style taxpayers or any other type of older building with a flat roof it is imperative that you take a quick second see if wooden cornices are present.  The reason for this is that in some cases the cornices are not on a parapet and are in fact flush with the roof.  In many they cases are completely tarred over, this will prevent you from knowing whether  you are standing on a solid roof or only standing on the cornice.  If you are accessing the roof via aerial ladder, it is vital that if you have to step off the aerial onto the cornice to aggressively sound the cornice area with a roof or rubbish hook before stepping on it.  Several firefighters have been injured and killed by cornices failing without ever being subjected to fire… they simply gave way under the load of the firefighter operating on them.

Fire Impingement onto Cornices

In building fires where the fire has vented out windows and the fire has started to impinge on the cornice an early and catastrophic collapse of sections of the cornice should be expected.  Also the wooden construction of the cornice can cause the fire to extend along the face of the building.  When dealing with a fire involving sections of cornices a collapse zone should be set up and respected.  During over haul the stability of the cornice should be checked, roof firefighters could attempt to remove it through traditional overhaul means or a from a tower ladder.  Also a stream from smoothbore nozzle could be used to attempt to knock the loose section of cornice off.  You want to try to control when the cornice will fail and not have it happen unexpectedly.

This is just one small building construction feature that firefighters often overlook the hazards of.  Francis L. Brannigan’s famous saying “know your enemy, the building is your enemy” holds even more true today, be sure to practice, train, study, (and most importantly) get out in your area and study building construction features common in the buildings in your district.

Troubleshooting a Flooded Saw – By: Kevin Legacy

5 comments

In some departments a quick on-scene replacement for a flooded power saw is simply a radio transmission away. Unfortunately for most, this is not the case. Everyone who operates one of these saws should know how to correct this common problem on scene.

When too much fuel and not enough air enter the combustion chamber a machine can flood. The spark plug gets coated with raw fuel and may not ignite. On a properly maintained machine, this can happen if you leave the choke on for too long or if the throttle lock is not engaged while attempting to start.  Flooding will not be caused by storing your saw on the rig with the throttle locked and the choke in the on position!  Of course there is the ever popular “I left the on/off switch in the off position while trying to start the machine”. Whoops!!!!.  If one of these errors occurs, and we catch the mistake in time, you can attempt the following to get the machine running.

Make sure the on/off switch is on. Turn the choke off. Push the decompression valve in. While holding the throttle control in the “full throttle” position, begin to crank the engine over. If the machine starts, hold the throttle control “full throttle” until the machine is running smooth and the excessive exhaust smoke clears up. This is easier with 2 firefighters.  

If the machine doesn’t start with the above method, replace the spark plug with the one you should be carrying in your saw kit. This can be done with the combination wrench that your machine comes with. The spark plug, in most cases, is easily accessible so it can be changed fairly quickly. Once changed, attempt to start the machine with the above procedure. If you are trained to use the machine you should know how to change the spark plug.  

Here is a video clip on how to change a spark plug on a Husqvarna 960.   

Forcible Entry Tool Modifications – By Andrew Brassard

4 comments

Since the existence of the fire service firefighters have been constantly trying to improve themselves and the tools they work with to adapt to the challenges that their communities present. This article is going to cover some of the basic tool modifications that firefighters have been utilizing for years. The majority of these modifications where spawned in smoky hallways and the backsides of taxpayers by members of the FDNY, the author is not taking credit for any of these modifications…… simply passing on the word.

Marrying up your Irons

Many departments use marrying straps to keep the axe and halligan together, some of these straps can be very simple or quite elaborate with built in shoulder straps and other fancy gadgets that all glow in the dark. The problem with these straps is that they usually don’t hold the tools together very well or can be very difficult to undo in zero visibility with your firefighting gloves on. A better solution for marrying these tools together is to use a hand file to notch out a very small path for the halligan forks to go, after the notch is created simply place the halligan forks into the notch and then give it a quick hit into the ground setting the halligan onto the axe.

Note: even though the tools are “locked” together you should

never fully trust that they will always hold together. Always use proper carrying techniques especially while climbing ladders.

One of the most common questions I get about doing this to your tools is “won’t that weaken the integrity of the axe?” The answer is yes it will weaken the integrity of the axe!! But think about it realistically, it would still take thousands and thousands of pounds of force to cause that axe to break and if you pushed the tool to that extreme the handle would break first.








The Sledgehammer Bracket

The sledgehammer is another favorite striking tool of firefighters. The sledgehammer should be at least ten or twelve pounds for effective striking. The biggest problem that the sledgehammer has is that it does not marry very well with the halligan; this is easily corrected by simply welding a bracket onto the top of the sledgehammer for the adz of the halligan to slide through. This will help hold the position of the halligan but will not keep the two from falling apart.

In my own opinion the flatheaded axe is a far more superior tool and gives the user a lot more options when it comes to forcible entry, the sledgehammer is a single functioning tool and can have its limitations in forcible entry. That being said the sledgehammer goes through brick and masonry much better than the 8 pound axe, if your response district has a lot of bricked up vacant buildings or is primarily commercial buildings the halligan sledgehammer combo works nicely.

The biggest thing when it comes to forcing a door is technique, if your technique is lacking, having a bigger and heavier tool is not going to help you get through a door quicker it will probably cause you to hurt yourself or your partner.

Squared off Shoulder

For any firefighter that has ever forced a door in zero visibility they know that it can be a challenging task, one of the best tool modifications I have ever seen is squaring of the shoulder of the halligan. By squaring off the shoulder of the halligan you create a striking surface to dive the halligan in between the door and the jamb in zero visibility without risking striking your partner with the axe or sledgehammer.

Another excellent place where this modification will pay dividends is in very tight or narrow hallways; depending on the swing of the door you may not have enough room to swing your striking tool effectively. For this method to work well place the fork in between the door and the jamb (after gaping the door) and place both hands at the back of the adz and push the tool into the door, slide the striking tool down the shaft of the halligan striking the squared off shoulder. This method works excellent but the technique must be practiced often and under realistic conditions to be effective and efficient on the fireground.

Chain Link

A simple method for ventilating windows in high rise or multiple dwelling is by ventilating the windows from the roof. By welding a chain link on your halligan close to the fork you now have a place that you can attach a carabineer and piece of rope to. After you have attached the rope simply lower the halligan to the window that needs venting, mark the spot on the rope with your hand and haul the rope and halligan back to the roof. After you get the halligan back into your hands you can throw the halligan off the roof, when the rope goes tight the halligan will swing back in towards the building breaking the glass. This is an extremely effective way to ventilate windows at fires in multiple dwellings.

These are a couple of easy modifications that you can do to your tools that will make them more effective on the fireground.

This is no place to come up with a plan!

Thanks to Tommy Hofland for sending this article over.  Tommy brings us an in-depth look at an SOP driven management style.

While my fire companies’ operations and our opinion of SOPs is in line with and supportive of the concepts expressed in this post, I was not able to clearly and concisely communicate a complete philosophy regarding SOPs until recently. Due to the generosity of the Puget Sound chapter of the Fraternal Order of Leather Heads I had the honor of attending a line of duty death funeral for a fallen brother in Maryland this winter. While staying with an friend who works for the Fire Department of District of Columbia, I was exposed to their SOP’s. The F.D.D.C. has written exceptional SOPs which lay out a detailed, thorough, explanation of not only how they operate at fires, but why this system works and how it addresses the multitude of challenges seen on the fire ground. I must give extensive credit to the men and women of the F.D.D.C. for both the inspiration and some of the exact wording for this post. Viva La Nut House!

When people are trapped and fire conditions severe, there is no time for rapidly arriving first alarm companies to formulate an incident action plan, communicate assignments, and evaluate the effect. Firefighters have to know what to do and what everyone else on the alarm will be doing. Their lives depend on it. Uncoordinated ventilation, hose lines stretched to the wrong location, and failure to assign forcible entry, proactive laddering or pick up the hydrant for the first due engine are all reasons firefighters have died in the line of duty.

The fire ground is no place to come up with a plan!

The NFPA defines Standard Operating Procedures as “An organizational directive that establishes a standard course of action.”

Management styles for fire ground operations are divided into two categories: those that are standard operating guideline driven, and those which are incident management system driven. A primary factor that determines a departments fire ground management style is the time it takes for units to arrive on scene. Departments that have long arrival times usually choose an incident management system style and those with short arrival times choose a standard operational guideline management style.

Departments that are capable of safely adopting a SOG driven management style allow for the rapid deployment and accountability of resources without direct instruction. This rapid deployment of resources provides the greatest possibility of overwhelming the incident problem; operating on multiple floors of fire simultaneously, and effecting numerous rescues without negatively effecting the safety or effectiveness of the fire attack. Incident commanders on full responses or box alarms will not have to assign units to specific tasks, because the SOG already assigns these units to a position and objective. This frees the incident commander to plan for and direct greater alarm units in mitigating complex fires and responding to unexpected problems or firefighter emergencies.

Well staffed Fire Departments have units strategically located throughout their city or district. Because of this, the difference in arrival times is frequently less than the NFPA standard eight minutes (if not seconds) between the first company to arrive and the last. In addition to rapid response times, well staffed cities are capable of placing multiple engines and trucks on scene with a first alarm strength of at least 15, if not more that 25 personnel.

Standard Operating Guidelines function effectively because units are assigned specific tasks based on the type of building occupancy and the fire companies respective response order. Units are guided by standard operating guidelines but have the flexibility to react to situations that present themselves at the scene of a fire. Any unit which will not be able to complete their assigned tasks, as directed  in the SOG, must notify the incident commander as soon as it becomes clear that their assigned task will not be completed. The incident commander can then give orders to ensure that all critical assignments are covered.

All units shall be assigned:

A position for their apparatus.

A responsibility for water supply or laddering.

A specific operating location within or around the building.

Specific tasks to be performed.

Responsibility for reporting a specific size up and benchmarks.

The assignments in the SOGs shall be strictly adhered to and the company officer shall be held accountable for compliance unless good reason or judgment warrants and prompt communication with and permission from the incident commander is received.

The ICS system shall be used on all responses. The ICS system shall be expanded using Divisions or Groups when more than seven operational companies are engaged in fire combat in or around the fire building. This will maintain a manageable span of control and allow for the safe addition of greater alarm companies onto the fire ground. Whenever a Battalion Chief is assigned to an alarm he is specifically designated with the authority and responsibility for ensuring the correct, effective, and safe implementation of the SOGs to mitigate any fire or emergency.

To effectively manage the response and emergency incident, the first due Battalion Chief will be in command of the incident and is the formal incident commander. First arriving companies are responsible for implementing the standard operating guidelines, making or directing critical adjustments to the guidelines, and communicating all deviations or problems to command.

Non-critical adjustments to the standard operational guidelines shall be directed to the incident commander in the form of a recommendation. The first due battalion chief, as incident commander, is responsible for the appropriate resolution of all emergency responses on which he is assigned, regardless of whether he has arrived on the scene or is responding.

Except when permitted by pre-plan, special provision, and orders en-route; all units responding on a Full Response or Box Alarm shall take their assigned position as based on their assigned response order. Companies may arrive on scene out of order by a few seconds. Despite technically arriving out of order, companies are responsible for their assigned duties and shall not assume the duties of another unit unless ordered.

Units shall make no effort to beet another company to an alarm and shall yield right of way to any company listed ahead of them on a response. Second due engines shall yield to first due companies, and third or fourth due engines shall yield to second due trucks. If a company will be significantly delayed for any reason, they must notify the incident commander.

Operations at the scene of a fire differ depending on the type of occupancy, building construction and the location and severity of the fire. The standard operational guidelines are intended to address the incident priorities of R.E.C.E.O. taking these and other factors into account. All members shall assist in mitigating the emergency by completing their assigned duties. Assigned duties are critical components of safe, effective, and efficient fire ground operations within the overall strategic plan.

Accountability of all personnel and companies is maintained through discipline. The SOGs describe the location, team member, supervisor, and assignment of all members on the scene. With out this system the ability to warn, aid or respond to a member or company in distress is significantly decreased. All members operating in a IDLH atmosphere must be backed up, have alternate egress provided for them, and be supported by other teams of firefighters who are available to assist them incase a firefighter emergency occurs. Through adherence to SOGs, companies can ensure that they are both providing and receiving this critical, mutual, support in the initial minutes of an incident as well as knowing the resources will be available to handle a more significant structural event, should one occur.

Engine companies will operate as one team towards their assigned goals. Engine companies perform rescues by placing their hose lines in a position to protect rescue operations and then extinguish the fire. Engine companies will operate as one team, in one location while inside the structure.

Members of engine companies shall be assigned specific duties based on their riding assignments.

Officer- Supervise the safe, effective operation of the company.

Driver- Establish a water supply and charge appropriate hose lines.

Nozzle- Advance and operate a hand line.

Back-Up- Assist with hose lays and assist with the advance of the hand line.

The truck company is responsible for the rapid location and removal of victims within the fire building and assisting the engine company in extinguishing the fire. To accomplish these goals, the truck companies must be capable of accomplishing a wide variety of tasks quickly, including: laddering, forcible entry, search, and ventilation. A truck officer should not have to give detailed orders because truck personnel should know, in advance, what their assigned tasks are and be able to perform them when needed. The truck company officer will not be able to directly supervise all members of the company because the truck personnel will be operating throughout and around the fire building. Truck company members must be capable of working in teams within or on the building or alone around it without direct supervision. Standard operational guidelines allow the truck company officer to know the location of all members, what they are doing, and when he should hear from them. Truck company members operating remote from their company officer shall be assigned specific size up responsibilities and tactical benchmarks which must be promptly communicated to their officer and command.

The members of truck companies shall be assigned specific duties based on their riding assignments.

Officer- Work with the barman to ladder and force entry on the front of the building, locate and confine the fire, and conduct a search of the fire unit.

Barman- Ladder, force entry, and horizontally ventilate on the front of the building and search the fire unit.

Driver- Ladder the roof and prepare to conduct vertical ventilation if needed, provide a roof assessment and 360 degree size up from the roof if safe to do so, assist with laddering and horizontal ventilation.

Tillerman (Outside Vent)- Check the basement, ladder, force entry and horizontally ventilate at the rear of the building, and then perform exterior searches behind and above the fire with the assistance of the driver or assist with vertical ventilation.

Specific company assignments, based on response order, vary based on building occupancy types.

Residential:

-House fires

-Row or Town House fires

-Apartment fires

Commercial:

-Store fires

-Warehouse fires

-Office fires

Common preassigned variations to the standard occupancy based fires are effected by the fires location, intensity, and building construction.

-Basement fires

-Top floor fires with heavy cockloft involvement

-Attached porch and garage fires

-Highrise fires

-Defensive operations.

Standard operational guidelines ensure that there is rapid coverage of the front, rear, fire floor, basement, floor above, roof, and top floor by both engines and trucks. The specific location and assignment varies by fire department practice, history, methodologies, and district lay out, particularly the availability of alleys. Common variations are caused by staffing, preconnect vs bulkbed operations and reverse lay vs forward lay water supply operations.

One possible model of operations would be as follows for a detached house fire.

1st Engine: Approach the front and pull past, preconnect fire attack, hand stretch supply line.

1st Truck: Park in the front, interior search of the top floor and horizontal venting and laddering.

2nd Engine: Park on hydrant, supply first engine, assist with the first hoseline.

3rd Engine: Lay into the alley, pull past or short of the fire occupancy, stretch a back up line to protect the search on the floor above the fire.

2nd Truck: Park in the alley behind the fire occupancy and assist the search and conduct vertical ventilation.

4th Engine: Pick up the 3rd Engine’s supply line, park on a hydrant and supply the third engine, stretch a back up line to the base of the stairs.

While there are many ways of coordinating the simultaneous forcible entry and egress, laddering of all sides, checking the basement, establishment of coordinated horizontal and vertical ventilation, attacking the fire, protecting the search and stairs with completely redundant lines, establishing two independent water supplies, and searching above and behind the fire; SOGs provide well staffed Fire Departments with the fastest, most effective means of rapidly placing numerous companies in the right place, at the right time, with the right tools to mitigate the emergency for our citizens and proactively get ahead of potential problems and hazards we encounter to keep our members safe.

Discussion:

This video is probably the most useful for showing the importance of pushing down ceilings after cutting the hole. Simply getting to the roof and cutting a hole does nothing to assist the interior crews if the fire has not entered the attic/cockloft area. It is clearly seen in several of these clips that there is a moderate to light smoke condition pushing from the ventilation opening until the members pushed the ceiling down. After the ceilings are pushed down in each clip, conditions changed drastically as the fire inside the building is successfully vented. Then and only then, will the members operating on the interior actually feel and/or see a difference in conditions. Note the wide-spread use of the “louver-cut” which is my preferred method when cutting a peaked roof. I have no idea how the videographer gets in position to take this footage, but we need a few more like him scattered throughout the country.

Notes:

- Clip 1: 1 second – 25 seconds:

  • Note the coordination between the members prior to pushing down the ceiling. One member turns around and appears to communicate that they are pushing down the ceiling.
  • Keep an eye on the member with the saw. In my opinion (and it might be the angle of the camera) he comes dangerously close to the member’s leg. As a rule of thumb, chain brake on or not, I keep the blade/chain of a running saw touching the roof so it cannot spin/rotate. This assures that I will not come in contact with another member’s leg.
  • Personally, I am uncomfortable if I sense or feel that someone is touching me while I am operating on a roof (especially a peaked roof and especially if I am operating a saw). I feel that I am more likely to be thrown off balance if I meet resistance or get more momentum as I move in a specific direction. The direction that I move may or may not be anticipated by the member “backing me up” and could cause an slight unintentional pull or shove in a direction that could throw me off balance.
    • With that said, several members have learned roof and saw operations while being “backed-up” (hand on coat tail, cylinder or belt) by another member. I don’t feel that there is a right or wrong way. Figure out what works for you and if you are not comfortable as a saw operator being “backed-up”, don’t be afraid to tell the guys working around the hole with you not to touch you.
    • If you are the firefighter on the roof that is expected to “back-up” a member operating a saw, NEVER touch the member operating the saw unless he knows your intentions. Your intentions are good, but many firefighters are more comfortable operating a saw without the “back-up” man in direct contact. Just because the member doesn’t want to be in direct contact, doesn’t mean that your job is complete. Conduct tasks such as: Assuring that the saw man does not walk off of the roof, monitoring radio traffic away from the saw so you can hear and assure the skylights, scuttles and bulkhead doors are opened up.

- Clip 2: 25 secs – 37 secs:

  • This clip shows an excellent example of what conditions may be like on a roof. If the weather conditions are right, the smoke may hang low on the roof and obscure vision. If this is the case, as with any other case where you cannot see your feet, GET ON YOUR KNEES AND CRAWL! When operating inside a building, it is very easy to walk into a hole in the floor or fall down a set of stairs. If you are in front of a burning store with a heavy smoke condition, you may fall into an open exterior cellar entrance. If you are walking on a roof in conditions such as the conditions in the video, it could be very easy to walk off of an edge of a roof or into a scuttle or ventilation opening. Remember, not all flat-roof buildings have parapet walls on all 4 sides. Sometimes the rear wall will not have a parapet. Take your time and crawl when you can’t see your feet no matter where you are. Don’t worry about looking silly, no one can see you anyway!

- Clip 3: 38 secs – 50 secs:

  • In this clip it appears that there is a scuttle in the bottom left of the video pushing heavy black smoke. Remember to open up ALL natural openings (skylights, scuttles and bulkheads) prior to starting a cutting operation. Interior companies are operating in the spaces served by the natural ventilation openings. They will directly benefit from those openings being ventilated first, and they are easier to complete. If you start a roof cutting operation prior to getting the natural vents, you may never get back to the natural ventilation openings.
  • The ventilation cut is working very well at this fire. I am not sure of the layout of this building or even what type it is, but IF the building is a multiple dwelling, I may have placed the cut a little further in from the left wall in an attempt to ventilate another room. If it is a corner like this, my goal is to come four feet from each wall and start there. Your cut should then vent at least two rooms unless the room is very large. Their cut placement seemed to work for them in the video, just something to think about.

The clips between 50 seconds and 1:46, I find to reinforce much of what I have typed above. If anyone has anything else to add, please jump in with the time in the video and your comments.

- Last Clip: 1:46 – End:

  • The members here may be operating on a bow-truss roof. It is hard to tell from the camera angle, but it appears that there is a slight bow in the roof. If it is a flat roof and I am wrong, I apologize but I would be remiss if I did not bring up the dangers of bow-truss roofs. If this is a bow-truss, a fire condition of this magnitude would be putting the members operating on this roof in extreme danger. Bow-trusses collapse with no warning and in huge sections.

Power Saw Tips

2 comments

On most modern power saws the base of the throttle housing is also part of the fuel tank.  A close up look reveals that there is also a seam in the molded plastic directly down the center of the throttle housing and tank.  Repeatedly placing your foot in the throttle housing while starting the saw will eventually cause the saw to crack along this seam.  The size of firefighting boots can also make it somewhat difficult to start the saw in this manner.  Next time you start your saw, try putting your knee on top of the engine housing instead of your foot in the throttle guard.

Over tightening the fuel cap is also a common bad habit.  The fuel cap should be tightened snugly but not overly tight.  When over tightened the rubber gasket that is intended to seal the cap pushes out from under the cap and can cause fuel to leak when the saw is picked up.

In the following youtube video you can see the ill effects of a fuel leak while using a power saw.  This accident appears to have been caused by the fuel cap not being installed or becoming loose during operation.  The same situation could have been created by a cracked fuel tank or over tightened fuel cap.

This is just one of MANY saw operation, maintenance, and safety tips Brotherhood Instructors’ Kevin Legacy will be presenting at FDIC on Wednesday March 23, 2011 from 1:30 – 3:00 pm.  Kevin brings years of experience using power saws in fire service and construction applications as well as small engine repair knowledge.

The Wide Adz – By: Andrew Brassard and Kevin Legacy

No comments

Hugh Halligan served the Fire Department of New York from 1916 until 1959. In those years of service, he had developed the most versatile and functional forcible entry tool ever conceived…The Halligan tool.

Although nearly 50 years old and no longer manufactured, the original Halligan tool has changed little in design. Today’s Pro Bar design closely models the original design, but does contain some slight improvements. The Halligan family can stand proud of the fact that this tool remains the tool of choice for any fire department that is serious about forcible entry.

Even though the basic design has changed very little over the years, some “in-house” modifications have surfaced in recent history to allow the Halligan to become even more versatile and user friendly. One such improvement is to simply square-off the shoulder of the fork. This allows an axe to be slid down the shaft of the tool and strike the back of the fork in zero or limited visibility environments. Another simple modification involves simply welding a chain link to the fork end. The chain link modification allows a firefighter on a roof of a fire building to ventilate top floor windows by attaching either a rope or a tool to the chain link. The modifications mentioned above are just two examples of how “simple improvements” have kept the Halligan tools innovative and versatile, even fifty years after it was created.

One of the most recent Halligan tool modifications is the “widened-adz”. The widened adz is accomplished adding nearly an inch of material to both sides of the adz. As legend has it, this modification evolved in the quarters of FDNY Rescue #2. A firefighter and talented welder, Sam Melisi would use the adz end of old Halligan tools and weld them onto the side of the adz on a new Halligan tool. This clever modification nearly doubled the width of the adz, which allowed the tool to supply a tremendous amount of force and leverage when “gapping” the door.

Not long after Melisi’s modification, several versions of the “widened adz” concept were born throughout the FDNY.

After years of forcing countless doors, the Halligan tool’s thickness would start to wear down near the chisel end. In some cases the tool would wear so thin, that the weld would either dimple, crack or even break. To defeat the wear issues, Firefighter Kevin LeGacy (FDNY Squad 61) came up with his own solution. Utilizing a MIG welder, Kevin would repeatedly lay down a weld on either side of the Halligan tool’s adz until the width of the adz was approximately doubled. After widening, he would smooth out the additional material with a file. A chiseled end is finally added to the adz to finish the job.

The impact of the wide adz is tremendous. On an inward swinging door, by simply placing the adz end between the door and the stop and prying up or down, (depending on which way the door opens) will allow members to defeat most doors in the “gap” stage of our forcible entry procedures.

Parapet Walls – By Chris Collier

2 comments

In a recent Brotherhood Instructors, LLC. lecture we discussed parapet walls and their hazards to firefighters.  Here is a little more explanation along with some photos to illustrate the point.  Parapet walls were typically brick or block construction but have changed over the years to incorporate other construction materials as well.  Regardless of construction type parapet walls are dangerous to UNKNOWING firefighters.  A little time spent researching and learning about parapet wall construction and past parapet wall collapses will make you a KNOWING firefighter and these construction features will be of little danger to you.  There are multiple methods of parapet wall construction, below are a few examples.

This photo is of a vacant/abandoned building in the Bronx, NY. Part of the parapet has already collapsed which gives us a nice view of the construction features that are normally concealed by the parapet. Towards the left side of the photo you can see the structural brick walls which continue up past the roof to create the parapet. To the right we can see the block construction with the metal I beam on top. The I beam spans the front of the store where the roll down gate and main entrance are located. Also visible are the “fire cut” roof rafters. The angled end of the rafters allows them to pull out of their pocket in the wall without acting as a lever and causing a collapse of the wall. This feature is sometimes effective and sometimes not. It is much less effective if the exterior wall has been tied back to the rafters at all. Another visible feature is the inverted or rain roof. These roofs are usually constructed of a 2×4″ frame which is held up by 2×4″ risers. The roof is slightly pitched to allow for drainage. The space between the ceiling and the roof is known as the “cock loft” and depending on the length of the inverted roof risers can be of considerable size.

This photo is of the other side of the building in the previous picture. You can again see the block wall extending past the roof to create the parapet and the inverted roof. Take notice of where the roof surface meets the parapet. This area, if not flashed or waterproofed properly can be a source of leaks. The water leaking into the building over time can freeze, causing expansion and weakening the structure. It should also be noted that metal expands when exposed to heat. This meta I beam, if exposed to fire, could very easily expand and push the masonry walls out of plum and cause a collapse.

This photo is of a newer style parapet wall. This building is of masonry and metal construction. The parapet wall has been added to make the building look much larger than it actually is. I believe this parapet wall to be metal framed with metal paneling over top. This parapet is significantly lighter than the masonry parapets per square foot but is still plenty heavy enough to kill members operating below it if it was to fall.

The following pictures show signs that are either on top of or attached to the front of parapet walls. Loads such as these need to be counterbalanced on the other side of the parapet for stability. The most common counterbalance method is to tie the parapet or the load back to the roof rafters. The tiebacks are lag screwed into the roof rafters. Deterioration from weather or fire can cause these tiebacks to become loose at their attachment points. When the tiebacks fail the parapet will either fail immediately or be extremely unstable until it does fail. Firefighters on the roof are in an ideal position to examine these building features and determine their stability. If there is any doubt about the stability do not be shy about notifying the incident commander and any members operating below.

Parapets can also collapse due to actions taken by firefighters. Parapets have been known to collapse after being hit with the stream of a master stream device or being bumped by an aerial ladder or tower ladder bucket. A general rule for defensive operations at a one story taxpayer (store) fire is to keep everyone off of the sidewalk. This beginning benchmark for a collapse zone is easy to identify and if done consistently will become second nature.

Quite a few firefighters have been seriously hurt or killed by parapet wall collapses.  Spending a little time learning about them may save your life or the lives of your brothers.  Construction is one of the most important topics for firefighters to be well versed in.  Any time spent on building constriction training or familiarization is time well spent.  If nothing else, google Francis Brannigan and Vincent Dunn and read everything they wrote.

Coping Stones – By Chris Collier

1 comment

Coping stones are a common feature on multiple dwellings and commercial buildings.  This simple construction feature can be hazardous to firefighters on the ground and those ascending to the roof if not understood.  These stones are held in place by mortar which can loosen up over time.  Water under the stones can freeze and expand which will also loosen the stones over the years.

When throwing portable ladders against the wall a small piece may break off and fall to the ground but rarely will the entire coping stone fall.  The real concern is when a firefighter ascends either a portable or aerial ladder to the roof and then goes to step off of the ladder.  These stones have a smooth surface which becomes very slippery when wet or covered with snow.  Also, these stones can have very fine cracks that are hard to see.  Once the weight of a firefighter is places on top of the stone it may crumble under the firefighters foot.  If the parapet wall is not very high it is best to try to step directly onto the roof surface to avoid slipping on the slick or broken coping stones.  If that is not possible be sure to hold onto the ladder tightly and check your footing before shifting your weight.  As always, when dismounting a ladder, drop your tools and equipment to the roof surface first.

When conducting your perimeter survey be mindful of loose coping stones as well.  Leaning over the roofs edge is necessary, just be sure not to knock loose stones off!

Trench Cuts: Where Do They Work? by Nate DeMarse

3 comments

Nationwide, there seems to be a lot of confusion regarding the use of the trench cut. In this “Trench Cut” series, we will discuss the background of the trench cut and the specific types of structures for which it was designed. As with several concepts in the fire service, the trench cut has been adapted and is now being utilized on other building types. In some cases this adaptation may work. However, we will discuss specific building types where trench cuts may not be the answer to a successful outcome. In some cases, it may even hinder the operation by “distracting” essential resources which may be better utilized by attacking the fire where it is NOW, instead of backing off, writing off an entire portion of the building and stopping it LATER. This is especially true in departments where manpower issues are common or constant.

The trench cut itself is one component of an overall strategy. Simply cutting a trench in a roof will not stop a rapidly extending cockloft fire. Several other things must be coordinated for a successful operation. Other components include: Removing and accounting for members from the area that we are giving up, completely pulling the ceilings directly below the trench and stretching additional lines to key locations above and below the trench. The overall strategy will be briefly touched in this drill. In an upcoming drill, step-by-step considerations for trench cuts will be discussed from a roof firefighters perspective

As stated above, the trench cut is one component in an overall strategy. Trench cuts can be used to cut off a rapidly extending cockloft fire at a pinch point. The pinch point or throat could be defined as an area where a building narrows sufficiently to perform a successful operation before the fire can extend past that point. This designated pinch point must be far enough ahead of the advancing fire to allow the trench to be completed, but not so far away that too much of the building is given up needlessly.

The trench cut is a defensive tactic and should be viewed as cutting a “fire break” in the roof. Although, the opening will allow fire, smoke and gases to vent from the cockloft area, the trench is NOT intended to act as a ventilation opening. A large ventilation opening must be cut over the fire BEFORE starting a trench cut. Failure to provide this large ventilation opening over the fire will ALMOST ALWAYS result in the fire jumping the trench and extending into uninvolved areas. In fact, if a normal vertical ventilation opening is not provided and a trench is cut and pulled remote from the fire area, it will certainly cause the fire to extend towards the trench (a new ventilation opening/path of least resistance) and into the uninvolved area that you are working to save. Additionally, the large vertical ventilation cut will buy extra time that is needed to make your additional cuts for the trench.

The trench cut was designed for buildings that have similar features as the examples below:

The first two photos are two different angles of the same building in the Bronx, NY. The arrows point to the throat where a trench could be cut relatively quickly to isolate the fire from the other wings. You can see how the narrowing of the building in the throat area would allow a trench cut to be placed with minimal effort and maximize the chances of cutting the fire off. The area where the arrows are pointing are 10-15 feet wide at their widest point. Keep these numbers in mind as you read further to other building types.

Photo three is another example using more recent building construction in a suburban setting:

This example in Westmont, IL has similar features as the building in the Bronx. While not a 6 story non-fireproof building, it does have it’s own version of a pronounced “wing” and a “throat” area.  A properly placed trench could be successful in this building.  This throat or pinch point is approximately 15 feet wide.

The trench cut was not intended to be used in these examples below:

This 1 story Class III strip mall/taxpayer measuring 150×50 is NOT a candidate for a trench cut. The likelihood of a trench cut being successful in this type of building is nearly nil. The features of this type of building do not provide a pinch point or throat area to successfully cut a trench. Lets discuss the tasks that MUST take place in order to cut a PROPER trench cut with a SUCCESSFUL outcome.

An initial ventilation hole measuring approximately 10′x10′ must be cut over the main body of fire. Most likely, with heavy fire conditions in the cockloft this cut should be extended to slow the lateral fire spread in the cockloft. Depending on the problems encountered, cutting and extending this initial ventilation opening could take several members operating two saws, five to fifteen minutes. To perform a trench cut correctly, this initial ventilation cut MUST be completed and therefore cannot be bypassed. At this point, we are approximately 15 – 20 minutes into the operation and we haven’t even started the trench.

To effectively cut a trench in this roof, you will have to cut the ENTIRE DEPTH of this building twice. This will equal 100 feet of linear cutting. Relief cuts every 3-5 feet along the trench will account for another 17 – 30 feet of cutting. Relief cuts are necessary so the roofing material can be pulled from the trench in pieces. To perform a trench cut operation CORRECTLY, the ceiling below must also be pulled so hose lines can be operated into the cockloft. The ceiling must be pulled from the front wall to the rear wall and ideally 2 to 3 bays wide (2 to 3 feet). That is approximately 150 square feet of ceiling that must be pulled. In old commercial buildings such as this, several ceilings including tin ceilings will severely hamper the operation. Manpower will also be needed to stretch and operate hose lines into the cockloft from above after the trench is pulled.

To summarize the numbers:

  • Members on the roof will need to do approximately 130 feet of linear cutting (not including multiple inspection holes & the initial large ventilation hole).
  • Members below will have to open up approximately 150 square feet of ceiling.
  • Members are needed to stretch multiple lines above and below the trench (not including the lines that are needed to attack the main body of fire)

This operation will take far too long to perform and require more manpower than most departments are able to muster. Use your available resources to stretch and advance additional 2 1/2″ lines, pull ceilings and expand the initial ventilation cut to slow/stop the fire travel in the cockloft and extinguish the fire. A rapidly extending cockloft fire would almost certainly overrun any trench operation started on this type of building before it could be completed.

Another Trench Cut No-Go:

Garden apartment or townhouse type complexes such as this one in Westmont, IL are also NOT candidates for a trench operation. Although the middle area of the building is a more narrow than either end, it is still 60 feet deep (30 feet from the soffit to the peak). Once again, there is no “pinch point” or throat to successfully place a trench cut quickly to effectively cut off a rapidly extending fire. The same problems present themselves here as they did above. These problems include over 200 feet of linear cutting, pulling massive amounts of ceiling and the associated manpower issues. However, there are a couple of advantages to this building type. The roof deck will typically be constructed of plywood or OSB and will only have one or two layers of shingles present and the interior ceilings will most likely be constructed of sheetrock.However, these two advantages should NOT lead you to the conclusion that a trench cut operation should be conducted on this type of building.

If you are going to spend time cutting 200 feet of roofing material and pulling 150 square feet of ceiling, do it near the the seat of the fire! If placed strategically, you could essentially cut the ENTIRE roof off of the fire apartment. How’s that for a ventilation opening to stop the lateral spread of fire?

Some officers and firefighters will argue tooth and nail that trench cuts should be utilized on the building types discussed above. Some departments will say that they have been successful in stopping fires in these building types by utilizing a trench cut. I ask those members and those departments this question: How rapid is the fire REALLY extending if you are able to spend 30 minutes to CORRECTLY perform ALL of the tasks described above to utilize a trench cut to stop the fire? I will lay money on the probability that in the majority of the cases nationwide, where a trench cut was credited with saving the building, it was most likely the aggressive operations of the interior companies opening the ceilings and exposing the fire in the cockloft from below. These companies in some cases probably worked without a primary ventilation hole which exponentially complicated their tasks.  In most of those cases, the trench cut was probably not warranted but seemed to coincidentally “work-out”.

This drill summarizes when and where trench cuts may or may not be warranted. I wanted to touch on the background and concepts of trench cuts before diving straight in on the “how-to” steps of cutting one.

As always, I would like to hear your thoughts. Do you agree, disagree, have any comments to add? Jump in brothers!

Size Up for a Down Firefighter- By: Andrew Brassard

1 comment

After locating a downed firefighter the packaging and removal process of the firefighter will be the next step. Packaging and removing a downed firefighter will without question be one of the toughest and most stressful operations that a firefighter will ever have to do in his/her career because we are now rescuing one of our own, the patient is no longer a faceless person but a fellow colleague and fellow brother.

After locating the downed firefighter a rapid and thorough size up of not only the patient but of the scene and conditions of the area were crews will be operating can make or break your RIT operation. A failed size up can lead to costly time delays or even worse causing your RIT team to be caught in a potentially life threatening situation (i.e. floor collapse, wall collapse, flashover, etc.)

Once the downed firefighter is located the RIT officer can start doing his/her size up, part of the RIT size up can include the S.A.F.E.S. acronym.

S- Size Up

Not only must the downed firefighter be sized up but the surroundings and location must be sized up as well, the use of a thermal imaging camera will pay huge divides in this situation. Things you want to look for in your size up should include:

  • Location of the firefighter
  • Conditions (fire and or heat) in the immediate area
  • Condition of the downed firefighter (is he or she breathing? Is there face piece still on? Are thy pinned or entangled?

 

If you do not have a TIC or the TIC is rendered useless due to fire conditions or a malfunction of the camera the size up will have to be done largely by feel. If the TIC does malfunction the RIT officer should call for an additional one to be brought to there location immediately should one be available. A TIC is an asset during the size up, that can sometimes be used to establish weather or not the downed firefighter is breathing. If the firefighter is passing air through the SCBA (breathing) the air bottle should be cold, this will cause the air bottle and air line to show up dark on the image from the TIC. This is not going to happen all the time based on fire/heat conditions and the downed firefighter exposure to heat or fire. As with all use of the thermal imager the user must be able to interpret what they are seeing in the image based on the fire/heat conditions around them.

You also want to get a sense of what kind of condition the downed firefighter is in:

  • Are they entangled? – do we have wire cutters to cut them out?
  • Are they pinned underneath something? – are we able to free them with the tools, equipment, and man power we have?
  • Do they have a face piece on? Is the SCBA or face piece they have on damaged? – do we have a way of getting this firefighter air? Do we have a new mask?

 

You also want to pay close attention to the fire and or heat conditions around the area of operation, is the area tenable, can we maintain an air supply to the victim and is there extra time to properly package the patient? Or are conditions rapidly deteriorating and we must remove the patient as quickly as possible? Remember the TIC may not give you a good indication of rapidly deteriorating conditions, only you experience and senses will give you a true sense of the heat conditions.

A- Assessment

Once you have located the downed firefighter you will want to complete a quick, proper, and thorough assessment of the firefighter to be removed. The best way to do this is to sit the firefighter up, one firefighter in behind the downed firefighter and on in front. Once you have the firefighter in position you can start your assessment, using the acronym

M. A. B. C. you can size use the air needs of the downed firefighter.

M- Mask- is the firefighters mask and regulator on and in place? Is it melted? Is it leaking air? There is not much point in attempting to transfill the firefighter’s air if it is going to leak out. Does this firefighter need his/her face piece changed out?

A- Air Exchange- Is the firefighter exchanging air (breathing)? The best way to tell this is to hold your breath and get your ear down towards the exhalation valve of the face piece.

B- By Pass- does the firefighters By Pass work?

C- Cylinder Pressure- What is the cylinder pressure of the downed firefighter? Do you need to transfill there air supply?

If the firefighter is found without there face piece on I would recommend utilizing the face piece in the RIT Kit, the reason for this is you would hate to go through all of the work to put the firefighters face piece on only to realize that it is defective and that was the reason for the firefighter having removed it in the first place.

F- Firefighter Needs

After insuring that the firefighter has an adequate air supply you can start to figure out what types of needs the firefighter will require to help with the extrication of the firefighter, the firefighter may only require to be extricated form the environment or he may require some additional equipment and or personal. Some of the additional firefighter needs maybe extensive depending of how trapped the downed firefighter is, some additional resources maybe as follow:

  • Bottle jacks
  • Pry bars
  • Air bags
  • Air tools
  • Saws
  • Rebar cutter
  • Etc.

 

You may also require additional personal to help clear out clutter or ensure that a clear path is ready for the extrication of the patient.

E- Extrication

Once the firefighter has been given a positive air supply we are ready to package and extricate the down firefighter. The quickest way to remove the firefighter is to do a conversion of his/her SCBA straps into a harness. There is nothing fancy about the removal of a firefighter in distress, it is simply a lot of work and there is no real way around it. There are some things that can and will make the removal of the firefighter easier, some of the ways are:

  • Utilizing a 2:1 mechanical advantage
  • Using your tools to help drag
  • Using the push pull method

Remember don’t waste valuable time doing the fancy a creative things the best thing for that firefighter is going to be getting them out of the IDLH atmosphere and into the hands of Paramedics, remember that the more simple you keep it the easier it will be to remember in a pressure situation.

S- Situational Awareness

Situational Awareness is probably the most overlooked part of the RIT process, but it is also the most vital. Firefighters tend to get caught up in the tasks of the RIT operation and tend to loose sight of what is happening around them. Maintaining that situational awareness is a very hard thing to teach firefighters, and it is an even harder thing to ask firefighters to do when they are focusing so hard on the monumental task in front of them. This is where the RIT officer must come in, the RIT officer must try to stay as “hands off” as possible to prevent getting tunnel vision and loose his/her situational awareness. Some things that you will want to constantly be aware of and monitor are:

  • Heat Conditions
  • Fire Conditions
  • Air Supply of your crew and yourself, you may have to call a “freeze” every once in a while and have the members check there air supply.
  • Monitor the progress of the crew; are they trying something that is not going to work? Do you have a different idea in mind? Are they making progress?
  • Monitor the radio
  • Give Command up dates as needed
  • Do you need a handline?
  • Additional resources? Try to stay 10 steps ahead of the game, don’t wait until something is needed before calling for it…… try to stay progressive
  • Is there another/better way out of here?

 

Remember that the best thing that you can do for the downed member is to get the out of the building as quick as possible, your size up should be very thorough but also must be very quick.  A proper a thorough size up can make or break your RIT operation or it could make the situation worse by creating additional downed members that must be rescued. The only way to become proficient at the task of a proper downed firefighter is through aggressive, realistic, and frequent training.

Active RIT: Preventative Maintenance – By: Dusty Dines

7 comments

There appears to be a current trend for Incident Commanders to keep their RIT/FAST team standing in the front yard like a piece of ugly lawn art. Most firefighters have an inherent nature and work ethic that is not conducive to standing in front of the building, and watching everyone else work. All of us know the feeling that occurs when responding to a confirmed fire. You are struggling to listen to the radio, adrenaline flows, you from a loose game plan….building layout…..type of building. As you pull out of your first due response area continuing towards the fire, you hear over the department radio, “Ladder XX, you are responding as the RIT team!”

The members in the rig immediately feel “deflated”. In addition, groans and sighs immediately follow the transmission, and typically members will again start talking about ESPN or dinner plans. This is very common in today’s fire service, as these highly motivated firefighters feel that they will most likely be standing in the front yard. The “deflation” is a very dangerous condition and may be considered one of the rawest forms of complacency. Why not give these firefighters active tasks that correspond with their RIT assignment, and improve the safety of members operating on the interior? These tasks will be completed on the exterior of the building, and still allow the RIT team to remain available in case needed.

Of course there are members of “management” who will resist this or similar operations. Those individuals will most likely hide behind the word, “freelancing”. In reality, the RIT team is not freelancing. They have been given assigned tasks and locations by their officer and are conducting those tasks to PREVENT a “mayday” situation. In fact, they are proactively starting or accomplishing their job! In the event of a “mayday” transmission, the RIT team members will return to the designated RIT area (where they would have been standing), and deploy to assist the stricken member(s).

Example:
A RIT company arrives to a fire in a single family or small apartment building. Upon arrival, the company officer locates the incident commander to confirm his arrival, and gather a briefing on the incident. The officer may even perform a quick 360 degree walk-around while the firefighters gather equipment and transport it to the designated RIT area. Upon the officer’s return, he/she may assign them to tasks that will aid the RIT team in case they are activated for a downed firefighter. These tasks WILL NOT include suppression operations, and will be conducted on the exterior of the building.

Example tasks:

- Perform forcible entry on rear and side doors
- Remove window bars
- Placing portable ladders under sills of upper floor windows.
- Clear out sashes of windows taken by interior companies

ALL tasks mentioned above provide egress for members operating within the building. ALL tasks mentioned above provide access for the RIT team, in the event the RIT team is activated. Finally, many of the aforementioned tasks can be accomplished in a few minutes, and usually with little exertion by the RIT team.

Modifications

Proactive RIT operations may be modified to various building types. In the event of a fire in a multiple dwelling/apartment building, the RIT team may add a lower floor reconnaissance to their list of possibilities. This will provide a layout of the fire apartment above. A radio transmission stating, “I am trapped in a rear bedroom” will no longer leave guesswork to the RIT team that is going to get the stricken member. Those members now know that they enter the apartment door, move down a hallway passing two doorways (a bathroom and a closet) and will then enter the third doorway to the bedroom. If an exterior route is chosen, they will know which windows to start placing ladders. If a fire occurs within a warehouse or other large commercial building, the RIT team may be utilizing search ropes or a LAST (Large Area Search Team) to rescue the stricken member. The RIT team may proactively look for objects to secure the rope, points of entry, etc…

Possible Obstacle and/or ProblemThe proactive RIT assignments that are discussed above are all completed while in direct communication of the RIT officer. At any time, RIT team members performing proactive tasks can drop what they are doing and report to the RIT staging area for deployment. The proactive RIT concept is not an excuse to “freelance”. If a team has a plan of attack, known assignments and are being supervised by their officer (either directly or via radio), it is not considered freelancing.

Advantages of Proactive FAST/RIT Operations

One advantage of the proactive RIT team lies in the fact that there will be a crew operating on the exterior of a fire building constantly performing a size-up and providing feedback to the RIT officer and the incident commander. While crews perform this size-up, they are gathering information on building construction, smoke conditions, fire travel and the progress and location of crews operating within the building. This information may allow crews to “predict” when and where a problem or “mayday” may occur and plan for those issues. The best “mayday” is one that is resolved before the RIT team is in operation.

Imagine a ladder company operating on the floor above the fire. A charged line is aggressively being advanced in the fire apartment and things appear normal. The ladder company above is conducting searches and opening up to check for fire extension. Suddenly, conditions change and the crew cannot exit from the entry point that they used. Conditions worsen, heat continues to increase rapidly while smoke banks down, and “maydays” are transmitted as they work their way to the rear bedroom window. Seconds later, the RIT team, (deploying to assist the stricken members) round the corner into the rear yard. They witness two members descending the ladder and the last member, an officer, stepping out of the window and onto the portable ladder. Over his head, heavy black, velvety, churning smoke is pushing under pressure from the window. The room lights up as the officer descends the ladder. The officer notifies the incident commander that all of his members are accounted for in the rear yard, and that his “mayday” can be cancelled.

This tragedy was averted because of proactive RIT/FAST team operations. Minutes before, the RIT team had placed portable ladders to several windows in the rear of the building. In the above case, the members on the floor above would have most likely resulted to jumping from the upper floor windows, unable to await the assistance of the RIT team. Proactive RIT/FAST operations turned a tragedy into a mere “close-call”.

Flat-Roof Operations: Safely Traversing the Roof

No comments

This is a series of photos resembles what you may see upon arrival.

Take a look at the last shot of the 4-side (d-side) at the roof level. The owners of this building sealed up the shaft at the roof what appears to be nothing more than a sheet of plywood. The weight of a fully geared firefighter would almost certainly fall through this if they stepped on this “feature of the building”.

Take a few seconds to give the building a look from the ground before heading to the roof. This dangerous feature would be invisible if looking at it on the roof. It will look like a substantial roof from front to rear, and you will have no way of knowing about the presence of the shaft on the 4-side.

One other tell-tale sign (not present in this photo) deals with the parapet wall. If a parapet wall runs front to rear, and there is a 10-15 foot opening in that parapet wall, this may be a sealed up shaft area.

Stay away from these areas while traversing the roof! They are deadly.

Stay safe!

This video demonstrates one method to expand upon the origional ventilation opening created using the 7-9-8 method.  Expanding the initial ventilation opening is better than creating a second.  Please feel free to reply with your comments or questions.

Control the Door – By: Nate DeMarse

No comments

On December 14th, 2010 we had a DOOR CONTROL post in this blog.  We discussed methods of controlling the door.  This post discusses why door control is important, as shown at a specific fire.  Other tips are also provided.

As the forcible entry and nozzle teams ascend to the second floor, they are met with a heavy smoke condition.  As they near this apartment, heavy smoke and fire are pushing from the cracks in the door shown above.  The paint is peeling, the top one third of the door glowing and distorted.  Time to go to work!

Destroying the integrity of this door during a forcible entry operation will certainly spell disaster for anyone (civilian or firefighter) operating or caught above the fire floor.  Many uninformed firefighters will opt to simply “bash” the door out of the frame (usually from the hinged side) with a sledge hammer/maul.  This technique is dangerous and unprofessional, and in many cases will not work!

If you are a firefighter that likes to “bash” the door in like a SWAT team, ask yourself these questions:

- What is the plan for door control if the engine is on a frozen/broken hydrant?
- What is the plan if the engine loses water?
- What is the plan if the fire cannot be controlled?

We are professionals, and our forcible entry operation should reflect as such:  This door (as should all doors) should be taken with the Irons, using conventional forcible entry techniques.  Gap the door, set the forks, and force the door ON THE LOCK SIDE.  Then CONTROL THE DOOR by grabbing the door with the Halligan or reaching in with a hook (pike pole) to close the door until a charged attack line is in position.  If any of the questions above surface during our operation, members can withdraw to the safety of the public hallway, and close the door until the problem is rectified, then resume the attack.  See the video below to review the steps described above:

This video is a real door, in a steel frame. It has two heavy locks in place, and an angle-iron shield which complicates the operation. It took less than a minute to force and control.

Note the cable wire (held in place in the ceiling corner by a plastic cover).  This plastic covering melts with very little exposure to heat, dropping the cable onto members entering/leaving the doorway below.

This photo shows two side-by-side doorways, typically both apartments will share the wall that runs between the doorways to an exterior wall.  A firefighter entering the right door to perform a search or advance oa hose-line on a fire should know that there are probably no rooms on the left wall, and all of the rooms are most likely located off of the right wall.  The apartment on the left will most likely be a mirror image of the right apartment.

This fire was on the second floor of a 6 story brick apartment building.  Several civilians were trapped on the floors above, including 6 unconscious civilians (an entire family) that were trying to make their way to the roof, but were trapped behind a locked steel gate in the bulkhead.  The unconscious civilians were actually found by the first and second due Roof Firefighters performing a sweep of the bulkhead (after forcing the bulkhead door to vent). All six civilians survived.

Although many departments may not have H-types or 6 story apartment buildings, the rules above also apply to garden apartments, “Main Street type” apartment buildings or private houses converted to apartments.

The Halligan Bar – By: Rob Fisher

17 comments

An excellent history lesson on the halligan sent to us by Lt. Rob Fisher from Snohomish County, WA.

One of the most versatile pieces of equipment used by the fire service today is the Halligan bar.  This tool has a rich history surrounding it.  To many, the tool has been considered one of the greatest advancements in the fire service.  Any great fireman would tell you if there was one tool they could take to work any job it would be the Halligan.

But, why is that the case?  And, where did it come from?

The Halligan was invented in the 1940’s by Deputy Chief Hugh A. Halligan of FDNY.

Hugh A. Halligan was first appointed to the FDNY on June 16, 1916.  He had worked countless jobs on some of FDNY’s busiest engines and ladder trucks as a fireman and later as a captain.  In this time, Chief Halligan worked with the Halligan bar’s two predecessors – The Kelly tool and the Claw tool.

The Claw tool was considered to be one of the first forcible entry tool used by FDNY.  This tool had been used on the job since the early 1920’s and was difficult to use.  As most had discovered through painful experience, the Claw Tool was heavy and the striking surface was off-centered, making it very dangerous for any firefighter holding it as it was driven into the door.

Then, a captain from Ladder Company 163, John Kelly, designed the next generation of forcible entry tool to be used by FDNY.  Naturally, it was called the Kelly tool.  This new tool did not have the large hook with the offset striking surface.  The striking surface was inline with the entire bar and had a 90flat surface (the adz) to the end.

The Kelly tool had a couple of downfalls; like the Claw tool it too was welded and still too heavy.  And, in those days, firefighters needed to bring both tools to the building due to their specific advantages.  Chief Halligan wanted to design a tool that could be held in one hand; one that would not chip or break at a critical moment; a tool that would not fatigue a firefighter; and one that could be used with safety and full efficiency.  After many hours of “trial and error” the Halligan bar was born.

The Halligan bar was made of cross-drop forged from one piece of No. 4140 (high carbon content) steel, weighed 8 ½ lbs.  Comprised of an adz, pick, and fork, the Halligan would prove to be one of the greatest forcible entry tools ever made.  The standard issue bar is approximately 30” in length, with a 15/16” shaft shaped into a hexagon for grip.  The fork is a minimum of 6” long taper into two well beveled tines.  Spacing between the tines allows for a gas valve to be shut off. The adz has a gentle curve for additional leverage, with a beveled end.  In addition to being used to break something, the pick and adz – only when properly used – provide protection to the arms, hands, and body of the holder during forcible entry operations.

As soon as the tool went on the market it was a huge success.  The Boston Fire Department was one of the first to place the Halligan bar on every ladder company in their department.

Now…one would naturally think FDNY had been the first to have them issued to their ladder companies.  Unfortunately, there was a small problem.  It was determined by those in higher places – let’s just say their favorite colors were white and gold – that there was a “conflict of interest” to have a member of the department selling tools or equipment back to the department in which they worked in.  The department’s hands were tied and the bars could not be purchased.  However, the bars could be purchased by anyone other than the department itself.  Ladder companies across the city began purchasing the Halligan bars with their own money.  The first company in FDNY to receive one was Ladder Company 47.  Coincidentally, they were the first due ladder to Chief Halligan’s home in Parkchester, NY.

The 2nd generation and later Halligan bars were printed on the forks with what looks like AM+D6.  It is, however, believed to be AMDG, which is a Latin acronym for Ad Majorem Dei Gloriam or “for the greater glory of God.”  This Latin phrase was a favorite of St. Ignatius of Loyola, founder of the Society of Jesus. Pope John Paul II routinely used it in his writings.  He would print AMDG in the top left of every page he wrote.

Chief Halligan was a very religious man.  It has been told that he would hand make a rosary for each new member coming into the FDNY.  After this task became too overwhelming, it was thought that Chief Halligan turned his religious influences into his bars by having each one printed with AM+DG.  This way he could spread the word to even more.

Folklore…wishful thinking…either way it’s a great story.  Only Hugh himself knows the true meaning behind this Hieroglyphics.  Who cares…the bar speaks for itself!

Most departments who carry the Halligan bar really don’t understand the value of this tool.  Unfortunately, too many of us do not get enough opportunities to become confident and proficient in the bar’s use.

Reading this article has only helped you understand the history of the Halligan bar.  To better understand why it’s the tool of choice of many firefighters (firemen), one must go to their engine or ladder, take it off…hold it…caress it, detail it and work with it.  Never set it down.  Bring it everywhere you go.  You’ll be surprised how many uses there are for this tool. Then – and only then – will they truly understand the impact the Halligan bar has made in the fire service.
