The steps of a Lock Out, Tag Out procedure

Step 1: Preparation - During the preparation stage, the authorized employee must identify all types of hazardous energy and gain a thorough understanding of the means for controlling the specific energy.

Step 2: Shut Down - This stage involves the actual process of powering down and locking out the machine or equipment. The shut down step also includes informing any employees who will be affected by the shutdown.

Step 3: Isolation - Isolating the machine or equipment means removing all energy sources, including turning off the power at a breaker or shutting a valve.

Step 4: Lockout/Tagout - The actual lockout/tagout step involves the authorized employee attaching a lockout and/or tagout device to each energy-isolating tool. The tagout refers to applying a tag on the device with the name of the person who performed the lockout.

Step 5: Stored Energy Check - Even with the energy source removed, it’s not a guarantee that no hazardous energy is stored within the machine or equipment. This step is necessary to identify any energy stored in the machine before performing maintenance.

Step 6: Isolation Verification - Once the machine or equipment is isolated from the source of power, locked out, and checked for residual energy, the last step is to double-check that each stage was completed correctly.
