Modular Cribbing – By: Mike Tesarski

One thing I've always liked about the Fire Service is the ability to improvise, adapt, and overcome problems. If you give a firefighter a problem you can be assured they will come up with an answer. I have always found it interesting to visit firehouses across North America and see different tools and equipment that have been modified or made “in-house” to solve a specific problem that the department or crew faced.

One such homegrown invention that firefighters have come up with is known as modular cribbing.  This invention came from the Mississauga Extrication Team in 1997, when the need for speedy vehicle stabilization was needed with limited manpower.

After trying a few versions of this cribbing the final product was perfected.  Modular cribbing is 6 4×4 wood cribs that are divided into two separate modules and screwed together firmly on two rubber mats (conveyor belt). Using a more solid piece of rubber allows the crib to be slid into space and rotated with ease. Each 4×4 is spaced 4 inches apart. This allows two tiers of 3 4×4 box cribbing to be stacked. This also allows for the two sheets of cribbing to be stored as one solid piece. Both pieces are held together with a metal bar slid through the middle where holes are drilled.  A handle made of a piece of seatbelt nailed to the end makes this easy to take off a truck shelf and carried to the scene.

To deploy the modular cribbing is a simple process. The cribbing point is selected and then the metal pin can be pulled, this separates the 2 individual modules allowing them to be stacked in opposite directions in place underneath the vehicle or what ever is going to be lifted. 

Another tremendous advantage of the modular cribbing is that because the cribs are tied together with the rubber matting it helps prevent the cribbing stack from slipping or inadvertently moving during extrication or lifting operations. The belting also provides a fantastic and stable platform for air bag operations

One point of contact on a 4×4 crib will hold approximately 6,000 pounds of force. With nine points of contact this cribbing will support up to 54,000 pounds which is ideal for stabilization of large vehicles or heavy machinery. Airbags can be used on top of the modular cribbing with ease and stability.

Having used this type of crib in competition and in "real life" scene I can tell you that it is extremely useful and quick.

We specialize in the basic fundamentals of firefighting. While we believe that hazardous materials, terrorism, emergency medical and the various rescue disciplines are essential parts of the Fire Service, we also think that the basic fundamentals of firefighting have been overlooked in recent years. We are here to help turn that trend in the other direction.

Power Saw Decompression Valves – By: Andrew Brassard
I have a question for you, is there any problem with leaving your chainsaw stored on the truck with the decompression valve pushed in? Wondering if moisture in the chamber might be an issue? We are attempting to be a little more efficient when it comes to our saws, but I can't seem to find…

If you don't then it could end up costing you quite a lot to get new Husqvarna chain saw parts to exchange those that are damaged. An electric chainsaw is by far the cheaper model tto run. Well, I was pleasantly surprised with this little guy.

I am the chief of training for the chillicothe fire department and I am interested in the Man-in-Machines class. Do you have any instructors in Illinois that could help us with this.

You prefer the Morris "Lil-Rex" to the Adz-Rex?

Rex Tool Modification by Andrew Brassard
Is the adz and Morris attachments equally effective? I carry the pig on my belt so it is always with me, so I was think of getting the lil-Rex (Morris/spike) tool.
