Video: Removing Glass Block Windows

Removing glass-block windows can be tricky and/or time-consuming if you are unaware of the methods to defeat them. In this video, we explain the quickest and most-efficient methods of defeating glass-block windows.

Of course any firefighter can simply start smashing blocks and get the window opened. The point of this video is to use a systematic approach to conduct this task with the least amount of work. After all, very few buildings have only ONE of these windows. If there is one, typically there are more.

In larger windows, members must be aware of large amounts of falling block that can injure a firefighter. Always be aware of what will or can fall, and remember that essentially you are causing a small “block-wall collapse” as you take these windows.



I would like to thank Commissioner Hoff of the Chicago Fire Department for this tip. In one of the first courses of my career, then Battalion Chief Hoff took time to show a small-town, 17-year old volunteer this method, and it has stuck with me. It is a prime lesson of “working smarter, not harder” to get the job done.

  • We recently had a project where we had to remove a 6ft by 6ft glass block wall. Something that we've done before but on a much smaller scale. With safety in mind, we first ensure the area (both inside and out) was clear. Then we started at the top of the wall and worked our way downward. This method is more timely but it ensures that huge panels of glass blocks are not falling on us.

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…

Firefighters and the Risk of Asbestos Exposure – Mark Hall, Guest Blogger
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.

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.
