Lockout/tagout procedures can vary significantly from project to project. For this reason everyone working on a project should know the policies for equipment lockout/tagout to create a safe work place.
Lockout Procedure
Think. Plan and Check:
- Identify all parts of any system that needs to be shut down.
- Find the switches, valves or other devices that need to be locked out.
Communicate:
- Tell affected employees you'll be locking out the equipment and why.
Locate the Power Sources:
- including stored in springs or hydraulic systems.
Neutralize all Power at its Source:
- Disconnect electrical.
- Block moveable parts.
- Release or block spring energy.
- Drain or bleed hydraulic and pneumatic lines.
- Lower suspended parts to rest position.
Lock Out all Power Sources:
- Use a lock designed only for this purpose.
- Each worker should have a personal lock.
Test Operating Controls:
- Turn on all controls to make sure the power doesn't go on.
Turn Controls Back to "Off"
Perform Necessary Repairs or Maintenance
After Maintenance is Finished, and Before Restarting Equipment:
- Remove tools.
- Reinstall machine guards.
- Make sure workers are a safe distance away while restoring energy.
- Notify others that the machines are back in use.
