ABS NISSAN LEAF 2013 1.G First Responders Guide

Preparation Items
Specification Purpose
Solvent resistant protection
gloves –
To utilize in the event of a Li-ion bat-
tery electrolytic solution leak.
Solvent resistant protection
shoes –
Absorbent pad The same pad used for internal
combustion engine fluids can be
used. To absorb any Li-ion battery electro-
lytic solution leakage.
Standard fire fighting equip-
ment 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 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)
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 automatically shut off at the time of deployment.
The Nissan LEAF 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 a Nissan LEAF, 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 2-1 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 procedures 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 Procedures
Once the high voltage battery is properly discharged, any of the following procedures can shut down and
isolate 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 Personal Protective Equipment (PPE) must always be used and the Li-ion battery and
high voltage components must not be touched.

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 at least ten (10) minutes have passed since the rescuer shut down the high voltage system (refer to
3-3.1 High Voltage System Shut-Down Procedures) , 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 Personal Protective
Equipment (PPE) must always be worn. DO NOT cut the Li-ion battery due to possible
electrocution risk and electrolyte solution leakage.
