What defines an electrically safe work condition?

An electrically safe work condition is defined by the presence of a conductor that is locked, tagged, and tested for absence of voltage. This approach ensures that all necessary safety measures have been taken to protect workers from electrical hazards. Locking and tagging a circuit prevents it from being accidentally energized while maintenance or work is being performed, serving as a clear indication to all personnel that the circuit is under maintenance and should not be operated.

Testing for absence of voltage is a critical step in confirming that there is no electrical potential present on the conductors, further reducing the risk of accidental electrocution or electrical injury. This comprehensive method of ensuring safety goes beyond simply turning off the circuit or visually inspecting it. It involves both physical measures (locking and tagging) and verification through testing, making it the most reliable standard for ensuring electrical safety in the workplace.
