10. Wait ten (10) minutes for complete discharge of the high voltage capacitor after the service plug
has been removed.
11. Perform the first response action.
3-3.2 Water Submersion Damage level of submerged vehicle may not be apparent. Handling a submerged vehicle
without
appropriate PPE will result in serious injury or death from electrical shock. • The ignition switch of the submerged vehicle must be turned OFF first, if possible.
Then
the vehicle must be completely out of the water and drained to avoid electrical
shock.
• Always wear appropriate PPE and remove/drain water before removing the service
plug
when working on a vehicle after a fire or submersion to avoid electrical shock.
• If the vehicle is in the water, to avoid electrical shock do not touch the high voltage
components,
harnesses or service plug.
3-3.3 Vehicle Fire • Always utilize full PPE and self-contained breathing apparatus during fire fighting
operations.
Smoke from a M35h HYBRID vehicle fire is similar to smoke from a
conventional vehicle fire.
• In the case of extinguishing a fire with water, large amounts of water from a fire hydrant (if possible) must be used. DO NOT extinguish fire with a small amount of water. In the event of a small fire, a Type ABC fire extinguisher may be used for an electrical fire
caused
by wiring harnesses, electrical components, etc. or oil fire.
Fire attack should follow standard fire fighting practices.
If you must walk away from the vehicle, notify an appropriate responder or a rescue person of the fact that
the vehicle is a hybrid vehicle and contains a high voltage system and warn all others.
During overhaul operations (late stage fire suppression process to examine for remaining sources of heat) ,
make sure the battery is fully cooled to avoid fire re-ignition. The battery could reignite if it is placed near fire.
To avoid possible electrical shock and serious personal injury, do not breach the Li-ion battery case.
