Study Notes

Safety Precautions

Do not make contact with high voltage components
Do not pierce through the hood with tools to gain access, as it may create a severe shock hazard
Do not cut orange-colored high voltage cables
Assume high voltage cables and components are energized when handling a partially submerged vehicle

Vehicle Fire Response

Treat a vehicle fire connected to a charging station as an energized electrical fire
Shut down the charging station before applying water
Use multiple hose lines (min. 2 x 65mm hose lines flowing 950 L/min) for extinguishment
Position crew and master stream device upwind at a 45-degree angle to the side of the vehicle
Secure a dedicated water supply

Incident Operations

Position apparatus uphill and upwind from the incident
Identify the vehicle and confirm if it's a LIB event
Immobilize the vehicle, chock the wheels, and disable the vehicle
Remove the proximity key to a safe distance (15m) and disconnect power (emergency cut loop)

Overhaul Operations

Use a thermal imaging camera when conducting a 360 size-up
Treat all conductive surfaces as if they are energized
Allow the vehicle to burn itself out in case of a burning high voltage LIB module
Apply water to the EV and exposures to mitigate the spread of hazards
Access the interior of the vehicle and apply water to the interior
Use large quantities of water to manage or control a battery fire

Additional Notes

Consideration should be given to waterways and sewers when applying water
Attempt to stop the flow of contaminated runoff into sewers and waterways
Contact Canutec (*666) for LIB information and confirm on-site information
Contact the vehicle manufacturer as an additional resource of information
