Which color designation corresponds to Administrative Equipment Process Control Locks in many facilities?

• A. Red Locks
• B. Blue Locks
• C. Green Locks
• D. Yellow Locks

Answer: (D)

Color coding in lockout/tagout systems helps workers quickly identify the kind of control that has been placed on equipment. Yellow is typically reserved for Administrative Equipment Process Control Locks, signaling that the lock is used to control a process in an administrative sense—during setup, calibration, or procedural changes—rather than to permanently isolate an energy source. The emphasis with this color is caution and authorization: only those with the proper administrative credentials can remove the lock and allow the process to resume, preventing accidental or unauthorized changes. This visual cue helps distinguish administrative process controls from other locks that are tied to energetic hazards, which are often colored differently in many facilities. In short, yellow matches the established association of administrative process controls with caution and coordinated process management.
