First Responder Considerations
Fire
The battery on fire will not explode. If battery cells reach high enough temperature, they vent and release
electrolyte. Battery electrolyte is flammable. Use copious amounts of water to cool the battery and extinguish
the fire. ABC dry chemical extinguisher will not extinguish a battery fire.
Water
The high voltage battery is isolated from the vehicle chassis. If the vehicle is immersed in water, you will not be
electrocuted by touching the vehicle.
Locate and review the Lithium-Ion Battery Chemistry Material Safety Data Sheet for more information.
