Preparation Items
Specification Purpose
PPE (personal protective
equipment):
Insulated gloves Up to 1,000V
For
protection from high voltage electri-
cal shock
Insulated shoes –
Safety
shield –
W
renches Size:10mm
T
o remove the 12V battery terminal
bolt.
Solvent resistant protec-
tion gloves
Solvent resistant
protection shoes –
To utilize in the event of a Li-ion battery
electrolytic solution leak.
–
Absorbent pad The same pad used for internal com-
bustion engine fluids can be used. To absorb any Li-ion 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 PPE (Personal Protective Equipment) Protective Wear Control
Perform an inspection of the 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 airleakage 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)

When arriving to an incident involving an INFINITI M35h 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
12V-Related Component Locations and Descriptions . Appropriate personal protective 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
Li-ion battery is deformed, broken or cracked, appropriate PPE must always be used and the Li-ion battery
and high voltage components must not be touched. • Failure to properly shut down the high voltage system before the Emergency
Response
Procedures are performed will result in serious injury or death from
electrical shock. To prevent serious injury or death, DO NOT touch high voltage
harnesses or components without always wearing appropriate PPE.
• When contact with high voltage components or high voltage harnesses is
unavoidable,
or when there is risk of such contact, you must always wear appropriate
PPE.

3-3.4 Cutting the Vehicle Body
• Do not cut into high voltage related areas to avoid severe personal injury or death.
• Do not cut into the Li-ion battery to avoid severe personal injury or death.
• When removing parts, DO NOT touch the high voltage parts or the insides of the
exposed orange-colored high voltage cables to avoid severe personal injury or death. • Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe
personal injury or death.
If ten (10) minutes have passed since the rescuer shut down the high voltage system (refer to 3-3.1 High
V
oltage System Shut-Down Procedure ) , then the rescuer can cut the vehicle except for the Li-ion battery.If the rescuer cannot wait the full ten (10) minutes or shut down the high voltage system,
absolute
care must be taken to avoid cutting HV parts and appropriate PPE must always be
worn. DO NOT cut the Li-ion battery due to possible electrocution risk and electrolyte solution
leakage.
