3-3 How to Handle a Damaged Vehicle at an Accident Scene
NO
TE:
If any air bags have deployed in the following 3 situations, the high-voltage (HV) system has
been designed to automatically shut off at the time of deployment.
The Infiniti Q70 HYBRID high-voltage system incorporates capacitors which are energized whenever the
high-voltage system is on. If the high-voltage system is shut down (either through one of the built-in
automatic mechanisms or manually through one of the procedures explained in this FRG) , the capacitors
will begin to gradually discharge. After 5 minutes, the voltage level will have dropped below 60V, and
complete discharge requires approximately 10 minutes after high-voltage system shut down. It is within this
period of time that responders must be most cautious.
When arriving to an incident involving an Infiniti Q70 HYBRID, the vehicle should be approached with
caution and inspected for the level of damage. In addition to overall vehicle condition (location and severity
of body damage, air bag deployment, etc.) , the high-voltage system should be assessed specifically. The
locations of the high-voltage component parts are illustrated in this FRG. Refer to 2-2 High Voltage-
Related
and 12-Volt-Related Component Locations and Descriptions (FRG–11) . Appropriate personal pro-
tective
equipment (PPE) must always be worn when approaching a vehicle of unknown condition, as
described in this FRG.
Situation 1) High voltage system intact, occupants can be accessed without extrication tools
The HV system can be shut down by following the procedure in this guide, while wearing appropriate PPE.
After HV system shut down, occupant assistance can begin immediately, and no wait period is necessary.
Situation 2) High voltage system intact, occupants cannot be accessed without extrication tools
The HV system can be shut down by following the procedure in this guide, while wearing appropriate PPE.
After HV system shut down, absolute care must be taken not to cut through or damage any HV system
wiring, battery 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 always 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.
3-3.1 High Voltage System Shut-Down Procedure
Any of the following procedures can shut down the high voltage system. The first response operation should
only begin after shutting down the high voltage system. If the vehicle is heavily damaged, for example the
high voltage battery is deformed, broken or cracked, appropriate PPE must always be used and the high
voltage battery and high voltage components must not be touched.

3-3.4 Cutting the Vehicle Body
DANGER
• Do not cut into high-voltage related areas to avoid severe personal injury or death.
• Do not cut into the high-voltage battery to avoid severe personal injury or death.
• When removing parts, NEVER touch the high-voltage parts or the insides of the
exposed orange-colored high-voltage cables to avoid severe personal injury or
death. Appropriate Personal Protective Equipment (PPE) must always be worn when
touching or working on high-voltage components. Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe
personal injury or death.
If approximately ten (10) minutes have passed since the rescuer shut down the high voltage system (refer to
3-3.1 High Voltage System Shut-Down Procedure (FRG–19)) , then the rescuer can cut the vehicle except for the high voltage battery.
If
the rescuer cannot wait approximately ten (10) minutes or shut down the high voltage
system, absolute care must be taken to avoid cutting HV parts and appropriate Personal
Protective Equipment (PPE) must always be worn.DO NOT cut the high voltage battery due to
possible electrocution risk and electrolyte solution leakage.
