Fire fighting
Use typical vehicle fire-fighting procedures to extinguish small fires that do not involve the High
Voltage battery.
Do not make contact with any High Voltage components during any overhaul procedures.
Always use insulated tools during overhaul procedures.
Always perform an adequate knock down to minimise any vapour before entering a hot zone.
Only use large amounts of water to cool the High Voltage battery if it catches fire, is exposed to
high heat, or is bent, twisted, cracked, or breached in any way.
Do not try to extinguish a fire on the High Voltage system with a small amount of water. Always
establish or request an additional water supply.
In the event that a vehicle connected to charging station is involved in a fire, treat the incident
as an energized electrical fire and shut down the electrical circuit that supplies the charging
station before applying water. Extinguishers classified for Class C energized electrical
applications can also be utilised.
High Voltage battery fires can take up to 24 hours to extinguish.
Protect the vehicle and the High Voltage battery from any exposures and consider allowing the
battery to burn.
Use a thermal imaging camera to make sure that the High Voltage battery is completely cooled
before leaving the incident.
The High Voltage Battery must be monitored for at least one hour after it is found to be
completely cooled. Any smoke or steam coming from the High Voltage Battery area indicates
that the High Voltage Battery is still heating.
Do not release the vehicle to second responders until no heat is detected in the High Voltage
battery for a minimum of one hour.
Always advise second responders that there is a risk the High Voltage battery can catch fire
again.
After the vehicle has been involved in submersion, fire, or a collision that may have
compromised the condition of the High Voltage battery, store the vehicle in an open area at least
50 ft (15 m) from any exposure.
