OSHA Lockout Tagout Standard: Application of Control 1910.147(d) (5) (6)

Stored Energy: After applying the Lockout Locks and tags, check for the stored or residual energies. Any residual energy ignored by any chance can be a potential danger, leading to accidents and fatalities. Therefore, it shall be relieved, disconnected, controlled, and otherwise rendered safe. Although the hazardous energy has been isolated in the previous step, stored, residual or potential energy may still be retained in the machine. To control potentially hazardous stored energy, the spring should be brought to a relaxed or neutral position. Verification of isolation shall be continued until the maintenance work is completed, or until the possibility of such accumulation no longer exists. The authorized employee is responsible to check, and verify that isolation and de-energization of the machine or equipment have been accomplished. Machines must be tried-tested-verified by visual inspection, to make sure that the energy isolation has been accomplished.

Some companies perform LOTOTO - Lockout Tagout Tryout, to confirm that the machine has been rendered safe.
