EV vs Gas Vehicle Fires: What’s in the Smoke?

Training & Consulting: https://www.stachedtraining.com

Over a three-year period, the UL Fire Safety Research Institute conducted full-scale burns on six electric vehicles and three internal combustion engine vehicles, collecting extensive air sampling and exposure data.

Two peer-reviewed research papers from that project are now published. In this video, I break down what was found in the smoke — including metals, fluoride, PAHs, PFAS, benzene, and the results of laboratory mutagenicity testing to determine whether the particulate matter could cause genetic damage under controlled conditions.

This isn’t a debate about EV vs gas. It’s a data-driven look at what responders and investigators may actually be exposed to on the fireground.
