What is the lockout rule?

Lockout tagout requires employers to be accountable for keeping workers safe from hazardous energy sources on machinery and equipment during servicing and maintenance. Who can remove the lockout tagout devices in a group lockout? According to OSHA's group lockout standard procedure, once the supervisor retrieves all keys from the lock box, the supervisor can then remove the lockout padlocks from the locked-out switch, machine, or equipment.
