Lockout Tagout: Electrical Room

Every year in the US, thousands of people are injured by electricity. Occasionally employees may encounter equipment and circuits that are energized or have the potential for energization while performing work activities. Without proper prevention, an arc flash may occur.

An arc flash (often called a flashover) is a type of electrical explosion or discharge that results from a connection through air to ground or another voltage phase in an electrical system. For example, when a wire makes contact with an earthed system. Working in or near electrical panels and systems increases your chance of exposure to an arc flash, and requires you take extreme precautions.
