wiring or components within ten (10) minutes of HV system shut down, but occupant assistance operations
using extrication equipment can begin immediately. The locations of the HV components are illustrated in
this guide.
Situation 3) High-voltage (HV) system damaged
If there is any evidence that the HV system has been compromised (such as arcing/sparking, orange wiring
harnesses cut or damaged, HV component casings damaged, etc.), the responder may still be at risk of
high voltage exposure. The vehicle must be approached with extreme caution prior to initiating any system
shut down procedures or rendering assistance to occupants. Appropriate PPE must be worn as
described in this guide, and the ten (10) minute wait time must be observed after HV system shut down in
order to ensure the system is de-energized.
In rare situations where vehicle damage is very severe, HV system shut down procedures as described in
this guide may not work. In these instances extreme caution and appropriate risk management must be
followed to prevent shock or electrocution to the responder or occupant.
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 power 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.
• 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.
