The following are examples of lockout tagout cases: A maintenance technician plans to repair a large industrial machine used in high-speed manufacturing. Technicians follow lock-out, tag-out procedures to isolate and de-energize machines before commencing work. Technicians begin by identifying all sources of energy, such as electricity and hydraulics, that will power the machine. They can also identify all stored energy in a machine, such as kinetic energy stored in rotating parts. Next, technicians isolate all energy sources by shutting down the machine's electrical and hydraulic power. They also use blocking devices to prevent any movement of the rotating parts of the machine. Technicians then apply lock-out, tag-out devices to each energy source and machine. They use padlocks and tags to secure the machine's main disconnect switch and hydraulic pump, and blocks to secure rotating parts. After ensuring that all lock-out and tag-out equipment is properly secured, technicians begin maintenance work. They lubricate the moving parts of the machine, clean any debris, replace any worn parts and perform other maintenance tasks. After the maintenance work is complete, the technician removes all lock-out and tag-out devices and restarts the machine. They also test the machine to make sure it is working properly and there are no loose parts. This lock-out, tag-out box keeps technicians safe from accidental start-up of machines and keeps machines running safely after maintenance work is complete.
