Since it was a frigid 40 degrees this morning in Florida, we realized that our brothers elsewhere in the world must be still dealing with quite a bit of snow. Snow loading is something we had never even heard of, let alone considered on any fireground down here. As a result, we are going to turn this post over to some folks who obviously know much more about this they we ever could: Deputy Chief Sean Toomey and Bill Greenwood. A special thanks goes out to them for allowing us to share this information.
Click here for an article written by Lt. Bill Greenwood from Keene (NH) Fire and FETC Services regarding roof snow loads. It discusses some tactical implications of operating under a snow loaded roof, and even explains the differences between warm and cold roofs.
Click here for an info sheet used by Concord (NH) Fire that includes instruction on how to assess and calculate a roof loads to determine collapse potential. This simple sampling and assessment process was developed by Concord’s Deputy Chief Sean Toomey, who happens to be a fire protection engineer.
The video below shows exactly how much of a hazard snow loads can be on the fireground.
Stay safe (and warm) out there in the snow brothers!2 comments
FDNY Ladder 45 showing that sometimes shortjacking is not an option. This is better than a supply line through the window any day!
It’s 04:00… Battalion arrives on scene of a working fire in a multi-family dwelling, people hanging from windows…What would you have done?
We know these pictures are already all over the internet, but we couldn’t resist. Unfortunately, we don’t know who to give proper photo credit to. We will however, be glad to buy the next few rounds for the Chauffeur of Ladder 45!28 comments
Lieutenant Landon Harris from Chesterfield County (VA) Truck 14 sent in these pictures of something he saw while visiting Cumberland, MD. As you can see from the photo, the building has transformers mounted directly to the building, just over a loading dock. This particular installation may pose some issues if we were operating in this building. For example, if fire were venting out of the bay door a significant hazard could exist. The proximity of the transformers to the loading dock may eliminate this area as an assess point into the structure. Ground ladders may also not be a viable option if they were needed on this side of the building. Finding this issue ahead of time, noting it on your pre-plans, and coming up with a plan of attack will be the key to a successful operation in this structure.
The increasing popularity of hybrids was accompanied by an increased amount of information provided to firefighters on how to deal with them when they have been involved in an accident. A quick internet search on anything hybrid related with provide a large amount of information geared toward firefighters. One interesting thing is that for the first time the automobile manufactures started to labeled things for us on the vehicle, particularly, what not to cut in an emergency. They have since taken this idea of providing information to firefighters one step further… The manufactures have now started to include information of where we should cut. These labels are now being utilized on non-hybrid vehicles as well. For instance, the pictures used in this post were taken on a full sized, four door, diesel pick-up truck.
Chevy, for example, calls these labels “First Responder Tags” and “Cable Cut Tags.” They install the “First Responder Tag” (shown above) near the hood opening directing to the proximity of the cut tags, and the “Cable Cut Tags” (shown below) are located on a cable near the under hood fuse panel. In this case, this truck (being a diesel) has two batteries. As shown in the photos, there is only one cut tag, leading us to belive that making one quick cut will disable the entire electrical system. So take it for what it’s worth. the manufactures are showing us exactly where to cut in order to remove the electrical hazards, or we could go old school and do traditional cable cuts near the battery, it’s up to you.
Tillerman Eric Wheaton from Winter Park Truck 61 sent in his “twist” on carrying a hook and ladder. This particular method allows the hook to not only remain in place on the fly section as it is extended, but also allows for the hook to remain in place if the ladder is rolled into a new position along the building. Rolling the ladder like shown in the video is an extremely fast way to move a ladder from one window to another when performing a VES operation.
In this method the hook is simply “hooked” onto the rung plate of the fly section on the inside of the beam. Eric has determined that hooking onto the 3rd rung plate from the tip seems to be the best location to ensure the hook remains in place while rolling the ladder. This method has been tested with a variety of different styles of hooks, and seems to work just as well regardless of hook preference.
Adding a small zip tie to the bottom of the hook may be an option to further secure it to the ladder if so desired. The idea behind the zip tie over a velcro or snapping strap is that a small zip tie will simply break away when the hook is tugged when being placed in operation. Another nice feature about this method of carrying a hook is that depending on the orientation of the ladder compartment on the rig, the hook may be able to remain stored in place all of the time since the hook rides on the inside of the beam against the rungs.
VentEnterSearch’s own Jimm Walsh will be co-presenting a webinar with Lt. Steve Crothers from Seattle Fire titled The Well-Choreographed Tiller Operation on Wednesday November 14, 2012 at 1pm EST. This free webinar is being hosted by FireRescue Magazine and firefighternation.com. Details for signing up for the webinar can be found by clicking here.
Here is a short description of the class:
Tillers are some of the most exciting apparatus to watch, but a smooth, safe, effective tiller operation requires an immense amount of training and coordination. Bringing your firefighters to a high skill level can be a significant challenge. Tractor-drawn aerials are extremely unique pieces of apparatus that requires formal training; the days of “on-the-job training” should be the way of the past. This presentation identifies the principles, concepts and dynamics of driving and tillering a tractor-drawn aerial and will prepare you to overcome the common pitfalls that tractor-drawn aerial operators encounter. You’ll have the opportunity to view unique perspectives that illustrate superior and standard tractor-drawn aerial fundamentals.
• Pros and cons of tractor-drawn aerial apparatus
• Key issues for maneuvering tractor-drawn aerial apparatus and how to overcome common placement obstacles such as narrow streets, overhead power lines, hills, etc.
• Common driving mistakes made by tiller operators and tips for improved communication between tiller operator and driver
• Factors to consider when spec’ing a tiller

When was the last time you checked your gas cans? Not just the fuel level, but the actual condition of the can? Have you ever taken the time to remove the spark/flame arrestor, and pour all of the fuel out? Check out the photos below to see why this may be a good idea.
These photos show the rust that was poured out of a normal looking metal gas can. The wire mesh that makes up the spark/flame arrestor may actually filter the larger chunks of rust keeping them in the can, but some of the smaller chunks may pass through. This rust could easily make its way into the saw and wreak havoc on a small engine.
There are many benefits to using metal gas cans: durability and compliance with legal requirements are probably the most important. However there is one important potential negative drawback. Rust! It’s just something we may have to deal with since plastic cans are not really an acceptable alternative, and are ultimately not fire service friendly.
The simple fix is to really check the conditions of all of your fuel cans, and have the department spring the $30 to replace that beat up 20 year old gas can and prevent damage from that $1500 saw.9 comments

Assistant Chief Michael Wolfschmidt from Surf City (NJ) sent in these photos of a simple modification they have made to their elevator key ring. Simply adding snap rings to attach each key to the main ring allows for easy removal. It is much easier to manipulate the lock with the single key than the entire ring. Unfortunately the one downfall to this modification is that it defeats the purpose of having all of the keys attached directly to the ring: It’s easier to misplace an individual key.
Another idea is to make a smaller ring with just one or two keys for the most common elevator doors found in your first due. The smaller ring will be used most of the time, and is much easier to work with without having to remove keys. It is also a good idea to make two set of the smaller rings with identical keys. (Obviously the one in the picture below is missing a key, but you get the idea.) This approach allows for the truck crew to split up and approach the top of the elevator car (to secure the power) and the actual elevator door (to facilitate the rescue) simultaneously. These simple tricks speed up the rescue, and make our job much easier.
