What must be done before an employee can work on or near live electrical parts?

Before an employee can work on or near live electrical parts, the essential action is to deenergize those parts. This is a critical safety measure designed to eliminate the risk of electrical shock, burns, or other injuries that can occur when working with live electricity. Deenergizing ensures that there is no electrical current flowing through the conductors, allowing workers to safely troubleshoot, repair, or maintain electrical systems without the fear of immediate hazards.

While conducting a safety meeting, wearing protective equipment, and getting permission from a supervisor are important practices within a safety program, they do not address the immediate risk presented by live electrical parts. Proper deenergization is the first line of defense in protecting workers from electrical hazards, and it must occur prior to engaging in any electrical work.
