when working on electrical switchgear, it must be and

When working on electrical switchgear, you must control energy sources to prevent unexpected energization. The safest approach is lockout and tagout. A lockout device physically secures the energy source, so the equipment cannot be energized while maintenance is performed. A tagout provides a warning and identifies who is doing the work and why, so others know not to energize the gear and who is responsible. Together, they prevent accidental re-energization and improve communication on the site. Merely powering down or unplugging isn’t enough in switchgear systems, since there can be multiple energy sources, stored energy, or backfeeds that could re-energize the equipment. A tag alone doesn’t stop energizing, and just powering down or unplugging may not remove all energy. That’s why lockout and tagout is the proper procedure.
