If a coworker is exposed to HV energy, what is the immediate action you should take?

• A. Stop work, secure the area, ensure the coworker is safe, call for medical assistance if needed, and only re‑energize after hazard controls are verified.
• B. Ignore and continue the task.
• C. Move coworker away during the task.
• D. Notify supervisor after shift.

Answer: (B)

Immediate safety action when someone is exposed to high-voltage energy is to stop work and secure the area, ensuring no one else can reach live parts. Check the coworker’s condition and provide first aid if trained, calling for medical help if there are injuries or symptoms. Isolate the energy source and apply the appropriate hazard controls (lockout/tagout and verification) before any attempt to re-energize. Re-energizing should only happen after you’ve confirmed all hazards are controlled. This sequence protects against electric shock, arc flash, and burns. Options that ignore the hazard, move the coworker during an energized state, or delay response fail to address the immediate risk.
