The National Fire Protection Association released this video on extinguishing high voltage battery fires in automobiles:

This video takes the data gathered through the HEV/EV high voltage battery burn study conducted by the NFPA’s Fire Protection Research Foundation and breaks it down into a series of tactical considerations and best practices for extinguishing fires in HEV and EVs. The following key areas are addressed:

• PPE recommendations • Water supply requirements • Extinguishment time considerations • Water application methods and tactics for maximum effectiveness • Recognizing the potential re-ignition and thermal runaway in a high voltage battery

• NHSTA recommended guidelines for storage of vehicles with burned or damaged high voltage batteries
