terminal
bolt.
Solvent resistant protection gloves
Solvent resistant protection shoes –To utilize in the event of a high-
voltage battery electrolytic solution
leak.
Absorbent pad The same pad used for internal
combustion engine fluids can be
used. To absorb any high-voltage battery
electrolytic solution leakage.
Standard fire fighting equipment
Standard fire fighting equipment.
Depending on type of fire
(vehicle or battery) use standard
fire fighting equipment (water or
extinguisher) . To extinguish a fire.
Insulated tape Insulating To cover any damaged harnesses to protect from and prevent
electrical shock. Tape should
cover all bare or damaged wire.
3-1.1 Personal Protective Equipment (PPE) Protective Wear Control
Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items.
3-1.2 Daily Inspection
This inspection is performed before and after use. The responder who will be using the items should perform
the inspection and check for deterioration and damage.
• Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and air leakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)
3-1.3 Insulated Tools
When performing work at locations where high-voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.

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 Q50 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. 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 Q50 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 never to cut through or damage any HV system
wiring, battery or components within approximately 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 approximate 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.

3-3.3 Vehicle Fire
• Always utilize full Personal Protective Equipment (PPE) and self-contained breathing
apparatus during fire fighting operations. Smoke from a Q50 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 high-voltage battery case.
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 at least 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–20)) , 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.
