The fire service is strained to develop response procedures for electric vehicle fires. Let it burn! But what if it is a busy city street? Never mind, use copious amounts of water! But what is in that runoff? Should I use a special new EV tool or fire extinguishing agent instead? Even though there are a growing number of EVs, there is still a lack of data on which to make decisions during EV fires.  This presentation will provide a working knowledge of battery fire science to make it clear how and why batteries burn differently than traditional fuels, how incident location can impact hazards, and to frame the EV fire problem. That working knowledge will be used to summarize Fire Safety Research Institute research findings assessing electric vehicle fire behavior and comparing it to modern gas-powered vehicle fire behavior. We will address whether EV fires are faster growing, bigger, and longer lasting and more likely to spread to the next vehicle or other exposures. The presentation will conclude with size-up and tactical consideration for EV fire incident response and best practices using the tools on every fire truck across the country: hoses, nozzles, and water.
