Your Guide to Equipment Lockout

When your machine has problems with components like brakes, tires or steering, you should place a personal lock on it so it cannot be operated, along with a tag that has your name, the date and time, and the reason for locking out.

The Steps:

1. Identify energy sources.
2. Neutralize energy sources.
3. Attach lock and tag.
4. Verify zero energy.
5. Complete the work.
6. Remove lock and tag.
   

Why lock out?

You or someone else could be hurt by operating unsafe equipment. When locked out, it cannot be operated until the problem is solved and the lock is removed.

Besides, it’s the law. See the Regulations for Mines and Mining Plants, Section 185 (7).

When to lock out:

If you think it might be unsafe to operate the piece of equipment, it should be locked out. If you are not sure, check with your supervisor.

How to lock out:

There are six basic steps to lockout, whether on a loader, a gen set, or other powered device:

1. Identify energy sources. The battery or electrical cable is the obvious power source — but don’t forget about hydraulic and thermal energy.
    
2. Neutralize energy sources. Shut off the engine, lower any raised components (like the bucket). Block components that can’t be lowered, using safety rated stands. Operate controls and follow manufacturers’ instructions to bleed any pressure left in the system.
    
3. Attach lock and tag. Equipment should have a lockable master switch. There may be other methods, like disconnecting battery cables.
    
4. Verify zero energy. Check to make sure no power is getting through and no pressure exists in any lines.
    
5. Complete the work. Follow your company’s procedures for recording work done and further work required.
    
6. When work is complete, do a circle check before removing the lock and tag and starting the engine.
