What should you do before leaving the EV work area at the end of the shift?

• A. Leave PPE on and leave the area as is.
• B. Re-energize HV system immediately.
• C. Remove PPE, ensure HV system is properly tagged or energized as required, secure tools, and follow LOTO removal and area hand-off procedures.
• D. Only remove PPE if asked.

Answer: (C)

At shift end in an EV work area, the key practice is to transition safely by confirming the equipment’s energy state, securing the work area, and communicating to the next person. Remove your PPE so you’re not leaving hazardous residues or creating a cluttered, trip-prone space, and then verify the high-voltage system’s status. If the work requires the system to be de-energized, it must be properly locked out and tagged, or if it’s to remain energized, you must ensure the necessary safety controls are in place and clearly conveyed. Secure all tools so nothing is left behind that could cause injury or equipment damage. Finally, complete the LOTO removal and area hand-off procedures so the next shift knows the exact state of the equipment and any remaining hazards. This approach protects you and others from unexpected energization and arc-flash risks, and ensures a clear, safe handover.

Leaving PPE on, leaving the area unchanged, re-energizing the HV system immediately, or removing PPE only if asked do not provide the full, proactive safety transition required.
