Lockout / Tagout: The act of locking out the potential hazard associated with a piece of machinery or area, and tagging the machinery to notify the machine operator that the machine or equipment has been locked out.
Maintenance personnel are required to maintain locks and locking devices for use in lockout / tagout procedures. The locks used must be unique in both appearance and function. This means that only the mechanic that owns the lock should have a key to his lock, and the lock must look different from other locks used at the site. Other forms of lockout include the use of wheel chocks, jack stands, and safety braces under raised blades and raised truck bodies, allowing the engine to cool before working on it, and relieving pressure on hydraulic systems before performing work on the unit. Tagout devices should be warning tags or steering wheel covers that alert the operator not to use the equipment.
It is illegal for anyone except the mechanic/driver that installed it, to attempt to remove a lockout or tagout device from a piece of equipment.
