Think, plan and check 

• If you are in charge, think through the entire procedure.

• Identify all parts of any systems that need to be shut down.

• Determine what switches, equipment and people will be involved.

• Carefully plan how restarting will take place.


• Notify all those who need to know that a lock-out tag-out procedure is taking place.

• Identify all appropriate power sources, whether near or far from the job site.

• Include electrical circuits, hydraulic and pneumatic systems, spring energy and gravity systems.

Neutralize all appropriate power at the source

• Disconnect electricity.

• Block movable parts.

• Release or block spring energy.

• Drain or bleed hydraulic and pneumatic lines.

• Lower suspended parts to rest positions.

Lock out all power sources.

• Use a lock designed only for this purpose.

• Each worker should have a personal lock.

Tag out all power sources and machines.

• Tag machine controls, pressure lines, starter switches and suspended parts.

• Tags should include your name, department, how to reach you, the date and time of tagging and the reason for the lockout.

Do a complete test.

• Double check all the steps above.

• Do a personal check.

• Push start buttons, test circuits and operate valves to test the system.

When It's Time To Restart

After the job is completed, follow the safety procedures you have set up for restart, removing only your own locks and tags. With all workers safe and equipment ready, it's time to turn on the power.
