The following are examples of lockout tagout cases: A team of electricians installs a new electrical panel in an industrial facility. Before commencing work, they must follow lockout, tagout procedures to ensure their safety. The electrician begins by identifying all the energy sources that power the switchboard, including the main power source and any backup sources. They then set about isolating these energy sources and making sure the panels don't reactivate during work. Electricians use locking devices such as padlocks to secure the master disconnect switch and any other associated electrical switches and control valves. They put a sticker on the lock saying maintenance is in progress and energy must remain locked. During installation, electricians must ensure that lock-out, tag-out devices remain in place and that no one attempts to remove them or restart the switchboard. They must also test the wiring to verify that no residual energy is present before starting work. After the installation is complete, the electrician removes all locking devices and restores power to the panel. Before the panels are used again, they will test them to make sure they are in working condition and meet all safety standards. This lockout tagout box keeps electricians safe while performing their work and prevents any accidental re-energization that could pose a significant safety risk.
