Step 1: Preparations

Prepare to turn off energy. Common energy types are (electrical, mechanical, air, etc…) and its potential hazards. Put the isolation protection device (safety lock) in place, and prepare to turn off the energy.

Step 2: Notification Work

Notify operators and managers of ongoing work that may be affected by isolating protected machines.

Step 3: Closing Jobs

turn off equipment or machinery

Step 4: Locking Work

Lock out all energy sources to shut down equipment or machinery using appropriate safety lockouts. When locked, make sure no one can open the switch or valve. Then attach a warning label to the safety lock to prevent accidental operation.

Step 5: Testing Work

Test all machine controls and circuits to ensure energy is fully isolated.

Step 6: Repair and Maintenance Work

Carry out maintenance according to different machine usage conditions, for example, some need to be maintained once a month, and some need to be maintained after a longer time…

Step 7: Return to normal operation

When all work is complete and the lockout/tagout is disengaged, verify that all tools and mechanical circuit lockouts are removed. Be sure to notify all workers before re-energizing.
