The personal lock of affected employees must be secured to the ______.

• A. Breaker
• B. Lanyard
• C. Hasp
• D. Faceplate

Answer: (C)

Lockout/tagout relies on a locking device that can hold multiple personal padlocks to keep an energy isolation device secured. The hasp is designed for this purpose: it fits over the energy‑isolation device (like a switch, valve, or breaker) and provides slots where each affected employee’s padlock can be inserted. With every worker’s lock attached, the device cannot be reenergized until all locks are removed, ensuring that everyone involved has acknowledged the shutdown.

A breaker is the energy‑isolation device itself, not the point where multiple personal locks are applied. A lanyard is used to carry or secure a locking device, not to secure the lock to the energy source. A faceplate is just part of the device and isn’t meant to receive multiple locks. So, the personal lock of affected employees must be secured to the hasp.
