EV TOOLS & SKILLS 101: CREATING AN ELECTRICALLY SAFE WORK ENVIRONMENT
Prevent Electrical Accidents with These Key Safety Principals
COMPILED BY EVBG STAFF AND LEGACY EV TRAINING TEAM
THE most effective way to prevent electrical injury is to eliminate the hazard by establishing an electrically safe work condition. An electrically safe work condition is a state in which a high-voltage electrical conductor or circuitit part, excluding the inside of the high voltage battery pack, has been:
● Disconnected or isolated from energized high voltage parts
● Locked out and tagged out (LOTO)
● Tested to ensure the absence of voltage, i.e. Zero Voltage Verified (ZVV)
The purpose of these criteria is to temporarily eliminate electrical hazards for a period of time while this state is maintained. By creating an electrically safe work condition, the person performing service is no longer required to wear personal protective equipment (PPE).
An electrically safe work condition is a state, not a procedure. Procedures must be developed specific to the component, system, and vehicle that the technician will work on, but in general, should be similar to the following example.
