When fighting a vehicle fire, no matter whether it is gas-powered or electric, your gear will pick up harmful contaminants. However, when an EV is involved, your exposure risk increases, by being exposed to heavy metals (and not the fun kind).
We recently studied how both electric and gas vehicle fires can contaminate firefighter turnout gear and what that means for your exposure.
By exposing swatches of turnout gear to full-scale EV and gas vehicle fires (with samples near the vehicle and in the smoke plume to represent different fireground positions), we found what remained in each of the three PPE layers:
•EV fires left higher levels of battery-related metals, like nickel, cobalt, and manganese, on turnout gear.
•The highest metal contamination was found in the smoke plume, which was up to 10× higher than positions closer to the ground.
•Both EV and gas vehicle fires left PAHs (a common group of harmful combustion chemicals) on gear at similar levels.
•Most contamination stayed on the outer shell, but some made it into the inner layers of the gear.
Our advice? Stay aware of your position on scene, especially around the smoke plume. Prioritize gross decon, proper handling, and thorough cleaning of your gear after the call to reduce ongoing exposure.
