Procedures and Responsibility

This procedure establishes the minimum requirements for the lockout or tagout of energy isolating devices. It shall be used to ensure that the machine of equipment are isolated from all potentially hazardous energy, and locked out or tagged out before employees perform any servicing or maintenance activities where the unexpected energizing, start up, or release of stored energy could cause injury from equipment.

Full time road maintenance workers will be instructed in the significance of the lockout or tagout procedures and are the only ones authorized to implement these procedures. The procedures in the Sequence of Lockout or Tagout System Procedure will be followed.

Sequence of Lockout or Tagout System Procedure
