Lockout Devices and Tags

Toolbox Talk:

Tags Are Not a Substitute for Locks

June 27, 2025

Tags are important for communicating that equipment is out of service — but they don’t physically stop energy from being released. Relying on a tag alone, when a lock is possible, puts workers at risk.

Why It Matters:

According to OSHA, tagout-only procedures are only allowed when the equipment cannot be locked out. Even then, the tag must be equally effective in preventing accidental startup — which is rarely the case in construction environments.

Key Points:

  • Always use a lock when the equipment has a lockable energy-isolating device.
  • Tags should clearly identify the person who applied them and the date/time of application.
  • Tags must be durable, securely fastened, and legible from a safe distance.
  • Never remove another worker’s tag or lock without proper authorization and procedures.

✅ Lock when possible. Tag when necessary. Never just hope it’s safe.

Ask the Crew:

  • Are we ever using tags when we could use locks?
  • Do we know the proper procedure for tag-only situations?
