Sawzalls, Think outside the box

Below is an article from Lt. Isaac Frazier, St. Johns County F.D. Florida.  Good read.   Sawzalls are a great tool that are becoming more and more functional for numerous scenarios.  Whether its extrication, or even fire ground operations they are a useful and effective tool.  With the proper training and familiarity you can accomplish allot of work rather quickly.  Get your hands on your companies tools, think outside the box, and continue to train.  Stay safe.


Extrication "Quick Tip" #23 (Guardrail Entrapments)

Do a quick internet search on vehicles vs. guardrails and your photo results will be endless. While guardrails are in place to protect vehicles/occupants from "dangerous" areas, many times they can add difficulty to an already challenging extrication. On occasion, guardrails will penetrate the occupant space and will need to be cut to facilitate patient removal. So the question is, what is the best way to cut guardrails?

Before we discuss cutting, we must first look at the most common guardrail type: the W-Beam. This rail is made of high-strength 10-12 gauge galvanized steel with a zinc coating to prevent rust. One thing we know about cutting galvanized material is the creation of zinc chloride/metal fume fever when using tools that cause high heat (torches, K12's, etc.) If this cutting is necessary it is recommended that it is done in a well ventilated area with respiratory protection. However, the method of cutting a guardrail will depend on how the rail is inhibiting extrication. Is the rail blocking the door, impaled in the patient, impaling the patient to the vehicle, or any trapping them by any other scenario?

I have found one of the best ways to cut W Beam rails is with a good sawzall/blade. Cutting with a sawzall limits movement of the rail, puts off limited heat, and allows a precise cut. We have had success with an orbital sawzall and fire rescue demolition blades. It is common to go through multiple blades, so have plenty on hand. Hydraulic cutters can be used but are not recommended if impalement is involved due to the torqueing of the rail. If there is no impalement we commonly use the hydraulic cutters to make the first "big" cut and finish with a sawzall.

The accident scene is not the time to practice cutting guardrails. Get with your local road and bridge department and get some material to practice cutting. It will allow you to find the "best" cutting method for your crew.
