Rescue Sheet
General Motors began a training program at the 2010 Fire-Rescue International in Chicago, using a pre-production Volt for a live extrication exercise. Chicago firefighters demonstrated the sequence of tasks required to safely disable the vehicle’s powertrain and its 12-volt electrical system, which controls its high-voltage components, and then proceed to extricate injured occupants.
With the 2016 Chevrolet Bolt General Motors created a simple 2 page Rescue Sheet to quickly explain how responders should handle the vehicle after a vehicle crash. Automakers started shorting their Emergency Response Guides to Rescue Sites last year. We expect this trend to continue.

Motor City Monday Extrication Tip; Electric Vehicle Battery Pack Reinforcements
As vehicles change, our knowledge must continue to keep pace and expand our mental toolbox. The extrication tool manufacters have kept pace with their cutters, spreaders, and rams to combact these strong steels. It’s our job to stay
Electric Vehicle Battery Pack Reinforcements
Like everything in life, vehicles are changing, well vehicles keep changing. World leaders are pushing green vehicles which will increase our interactions with electric vehicles. First off, let’s look at the common acronyms of several common green and traditional vehicles.
- BEV = Battery Electric Vehicle
- PHEV = Plug-in Hybrid Electric Vehicle
- HEV = Hybrid Electric Vehicle
- ICE = Internal Combustion Engine
Unlike BEV, PHEV, and HEV, the term ICE refers to the engine itself, rather than the type of car. Normal/traditional gasoline and diesel cars have internal combustion engines.
Electric Vehicles present several challenges to firefighters with battery fires leading the way. The automakers are designing and engineering extremely strong protective cages around battery packs. We are no strangers finding boron, martensite, and press hardened steels in the pillars, roof rails, and fender wells. However, in a BEV, the rocker panels and cross vehicle reinforcements will have boron and martensite steels to protect the battery pack from collisions that could comprise it. In the images below, the 2021 Ford Mustang Mach E has this strong steel in the rocker panels and cross vehicle reinforcements. The automakers can tie in the strong rocker panels into the front fender wells requiring us to make deep cuts during a dash lift or roll.
The image below shows the different testing vehicles are subjected to and a strong battery cage can not only protect the battery pack, but also the occupants of the vehicle.
As vehicles change, our knowledge must continue to keep pace and expand our mental toolbox. The extrication tool manufacturers have kept pace with their cutters, spreaders, and rams to combat these strong steels. It’s our job to stay current where the automakers are using strong steel.

Heavy Rescue
Dump truck rolled onto a car
The dump truck attempted to change lanes, struck the passenger car, the load inside the rear of the dump truck shifted, causing the vehicle to list to one side and roll onto the driver’s side roof of the vehicle.
Manheim Township, PA
First off, both drivers required extrication from their vehicles and were taken to the hospital with non life-threatening injuries.
