Proper lockout/tagout practices and procedures safeguard workers from the release of hazardous energy. The OSHA standard for The Control of Hazardous Energy (Lockout/Tagout) (29 CFR 1910.147) for general industry, outlines specific action and procedures for addressing and controlling hazardous energy during servicing and maintenance of machines and equipment. Employers are also required to train each worker to ensure that they know, understand, and are able to follow the applicable provisions of the hazardous energy control procedures. Employees must be trained the energy control program and have the knowledge and skills required for the safe application, usage and removal of the energy control machines.
The employees who work in the area where the energy control procedure are utilized need to be instructed in the purpose and use of the energy control procedure(s) and about the prohibition against attempting the restartup of the machines or equipment which is locked or tagged out.
The employees who are authorized to lockout machines or equipment and perform the service and maintenance operations need to be trained in recognition of applicable hazardous energy sources in the workplace, the type and magnitude of energy found in the workplace, and the means and methods of isolating and controlling the energy.
It's a good choice to retrain of all employees to maintain proficiency or introduce new or changed control methods.
