6. In Case of Fire
First responder:
• Provide large quantities of water to extinguish the re
• Monitor the temperature of the battery after extinguishing
• Arrange for evacuation. Remember that the battery might reignite
• Quarantine the vehicle in case of reignition
HVbatteryres:
• Flooding a battery with water can extinguish it
• If no water is available, use a dry chemical or other typical re-extinguising agent until
water is available
• The battery can create dangerous gases when it ignites
Gaining access to battery:
• If it’s determined safe to do so, raise or tilt the vehicle to gain direct access to the battery
• Do not open the battery
• Only apply water inside the battery if a natural opening exists
Reignition:
• The battery could reignite if it is placed near re
• Check for remaining heat sources with a thermal imaging camera
• Make sure the battery is fully cooled before moving the vehicle
WARNING
If the electric vehicle is on re, it can be extinguished with large quantities of water. Use
water from a hydrant or other nearby water sources whenever possible.
Lithium-ion batteries can spontaneously self-ignite. Batteries can reignite after a re has
been suppressed. This can occur several hours after an event that causes damage. Always
wear the appropriate PPE and self-contained breathing apparatus during reghting
activities.
Extinguishing a Fire
NOTE
The HV battery system has lithium-ion cells. If this type of battery catches re, it has a low
risk of explosion because it contains an oxidizer. This type of battery will continue to burn
until it is completely burned out.
