PROTECTIVE WEAR CONTROL

• Perform an inspection before beginning work, and do not use any items where abnormalities are found.

DAILY INSPECTION

This inspection is performed before and after use, the worker in responsible who will directly use the items

inspects them and checks for deterioration and damage.

• Insulated gloves

CAUTIONS AS TO HIGH VOLTAGE

Inspect the insulated gloves for scratches, holes, and tears. (Visual check and air leakage test)

• Insulated safety shoes

Inspect the insulated safety boots for holes, damage, nails, metal pieces, wear or other problems on the

soles. (Visual check)

• Insulated rubber sheet

Inspect the insulated rubber sheet for tears. (Visual inspection)

INSULATING TOOLS

When performing work at locations where high voltage is applied (such as terminals), use insulated tools.

HANDLING OF INSULATION RESISTANCE TESTER

CAUTION:

Unlike the ordinary tester, the insulation resistance tester applies 500V when measuring. If used incor-

rectly, there is the danger of electric shock. If used in the vehicle 12V system, there is the danger of

damage to electronic devices. Read the insulation resistance tester instruction manual carefully and

be sure to work safely.

PREPARATION ITEMS

A: Hold glove and fold as shown in the figure.
B: Fold three or four more times, preventing air from escaping from the glove.
C: Squeeze glove to check that the glove has no holes.

HOW TO HANDLE THE DAMAGED VEHICLES AT AN ACCIDENT SCENE

High voltage system shut-down procedure

Shut down the high voltage system according to vehicle damage level. Any of the following procedures can

shut down the high voltage system. The first response operation should be done 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 be used and the Li-ion battery and high voltage components must not be touched.

DANGER:

•

Failure to properly shut down the high voltage system before the Emergency Response Proce-

dures are performed may result in serious injury or death from electrical shock. To prevent from seri-

ous injury or death, DO NOT touch high voltage harnesses or components with bare hands.

•

When contact with high voltage components or high voltage harnesses is unavoidable, or

when there is risk of such contact, be sure to wear appropriate PPE.

WARNING:

•

If the charge connector is connected to the vehicle, remove it. Refer to Removing the Charge

Connector.

•

The vehicle contains parts that contain powerful magnets. If a person who is wearing a pace-

maker or other medical device is close to these parts, the medical device may be affected by the

magnets. Such persons must not perform work on the vehicle.

• Be sure to check the READY indicator in the instrument cluster, and verify that the READY indicator

is off and the high voltage system is stopped.

• There is a possibility of remaining high voltage in the air conditioning system by the remote air con-

ditioning system. If the READY indicator is turned OFF and the air conditioning remote timer indica-

tor is turned ON the high voltage system is active. Please ensure that the air conditioning remote

timer indicator is turned OFF and the air conditioning system is inactive.

• After high voltage system shut-down, please wait for 10 minutes for complete discharge of the high

voltage condenser. While waiting, do not operate any vehicle functions.

• The high voltage full discharge takes 10 minute, but after 5 minutes the voltage has dropped below

60 V.

• Remove the 12V battery negative terminal and wait for 3 minutes to discharge the air bag condenser.

Even though the 12V battery negative is disconnected, the Supplemental Restraint System (SRS) air
