What Do the Colors Mean on Lockout Tagout Locks?

Lockout Tagout (LOTO) safety padlocks are essential for preventing hazardous energy releases in industrial settings. One key feature of these locks is their color-coding system, which helps workers quickly identify the purpose, user, or department associated with each lock. Understanding these color codes ensures better compliance with safety protocols and reduces workplace accidents.

Common LOTO Lock Color Codes and Their Meanings

Different industries and companies may adopt slightly varied color-coding systems, but the following are the most widely recognized standards:

Red: Typically indicates danger or emergency stop. These locks are often used for general lockout procedures or to mark critical hazards.

Yellow: Represents caution or controlled energy. These locks may be used for maintenance or when equipment is partially operational.

Green: Signifies safe conditions or normal operation. These locks might be used for non-hazardous maintenance or testing.

Blue: Often designates information or special instructions. These locks may be used for specific departmental procedures.

Orange: Used for warning or temporary lockout situations.

Black, White, or Other Colors: Some companies assign unique colors to different departments, shifts, or individual workers for easy identification.

Standardizing LOTO lock colors improves workplace safety by reducing confusion and ensuring that only authorized personnel remove locks after completing maintenance.
