Approaching a Damaged High Voltage Vehicle



ALWAYS ASSUME THE VEHICLE IS POWERED UP

Rules apply when approaching any potential high voltage situation. Always follow your high voltage safety training. Some pre-cautions to take in any high voltage situation include:

- Remove all jewelry, watches, necklaces, earrings, etc. Metal objects are conductors of electricity.

- Wear the necessary protective clothing (high voltage rubber gloves, face shield, insulated boots, protective raincoat or apron)

- Bring the following equipment:
- Class ABC type fire extinguisher
- A non-conductive object - about 5 feet long (1.5 meters) - used to safely push someone away from the vehicle if they accidentally become in contact with high voltage.

APPROACHING A DAMAGED VEHICLE
- Disable the high voltage electrical system using as many of the following steps as possible.

- Secure the vehicle - Put the shift lever into Park. Remove the ignition key. Block the wheels if necessary. Removing the ignition key or turning it to the off position will disconnect the high voltage system.

- Disconnect the negative cable from the 12-volt battery this will also disconnect the high voltage.




- If possible - remove the High Voltage Service Disconnect Switch by turning it counter clockwise and lifting out. (See section on Hybrid components for location). The High Voltage Service Disconnect Switch should be re-inserted into the service or shipping position.

WARNING Removing the High Voltage Service Disconnect Switch disconnects high voltage from the vehicle. The individual cells inside the battery pack will still be charged. Do not cut into the high voltage battery case or penetrate the batteries in any way.
