Step 4: Apply Lockout/Tagout

Apply locks and tags to prevent/warn against the reenergization of the equipment. When applying locks and tags, follow all these guidelines:

• Attach a lock and tag to each isolation point.
• Attach locks in a way that holds the EIDs in the “safe” or “off” position.
• Attach tag as close to the EID and lock as possible. A tag must accompany every lock.
• It is a good idea to also tag the point of operation if it is located remotely from the isolation point(s).
• Each lock should only have one key (no master keys are allowed).
• Every worker must place their OWN PERSONAL LOCK on the system. There should be as many locks on the system as there are people working on it. If a maintenance job requires 3 workers, then 3 locks should be present. Locks must only be removed by the individual who attached them.
