What is the procedure for lockout/tagout when working near energized lines?

• A. Do nothing.
• B. Lockout or tagout the lines where possible, maintain clearance, verify de-energization with appropriate meters, never touch lines.
• C. Shunt the lines to ground.
• D. Notify supervisor only.

Answer: (B)

Lockout/tagout around energized lines centers on preventing unexpected energization by isolating the energy source and confirming it’s truly off before you work. The safest approach is to lock out the lines when possible, or use a tagout if a lock isn’t feasible, then establish a safe clearance and verify that the line is de-energized with appropriate meters before touching anything. This verification is crucial, because it confirms there is no voltage and no stored energy that could surge when you move or make contact. Never touch the lines, and maintain the required clearance to avoid any contact or arcing.

If a lockout isn’t possible, a tagout still communicates that the equipment must not be energized and you must maintain control of the energy state, but it relies on others to honor the tag, so strict procedures and visibility are essential. This approach significantly reduces the risk of electric shock, arc flash, and accidental re-energization.

Doing nothing is unsafe, and shunting lines to ground can create hazardous fault paths and does not reliably ensure de-energization. Notifying a supervisor alone does not eliminate the energy hazard or protect you while you’re near the lines.
