Study Notes
- Electric and hybrid vehicles do not make sound, making it difficult for first responders to approach safely.
- SOP/SOG procedures should be followed to ensure safety in incidents involving electric or hybrid vehicles.
- SAE recommended practice standard J2990 categorizes potential hazards as chemical, electrical, or thermal.
- High-voltage cables in hybrid electric vehicles are identified by their distinctive orange color.
- Hybrid electric vehicles have plastic conduit color-coded to identify potential risks.
- The high-voltage battery box in hybrid electric vehicles is positioned for maximum safety.
- The correct procedure for depowering the high-voltage circuit is to remove all fuses and relays.
- The hot stick tool can be used to move orange cables out of the way.
- A shepherd's hook tool may be used to remove a person from high voltage.
- Contact with high-voltage components can cause serious injury or death, but receiving an electric shock from a hybrid vehicle is highly unlikely.
- Emergency responders should follow standard operating procedures (SOP) for vehicle incidents.
- Identify the vehicle as soon as possible to determine if it is an electric or a hybrid electric vehicle.
- Disable the vehicle by removing the ignition key or fob, moving the key or fob away from the vehicle, and turning the ignition off.
- Stabilize the vehicle by chocking the wheels and setting the parking brake.
- Access the occupants using normal removal procedures.
- Cut the 12-volt battery cables using the double cut method with insulated cutters.
- Use water or foam to extinguish a fire in a hybrid vehicle and perform a fast, aggressive fire attack.
- Offensive fire attack involves flooding the high-voltage battery pack with water to control the fire.
- Defensive fire attack involves pulling back a safe distance and allowing the NiMH battery modules to burn out.
- Hazmat materials may be present in hybrid vehicles, including the high-voltage NiMH battery electrolyte, which is a caustic alkaline.
