When removing covers from electrical panels but leaving the deadfront in place are employees required to wear Arc Flash protection and follow approach boundaries? This is commonly done for visual investigation.
I understand that employees must be protected from exposed energized parts. The definition of Exposed (as applied to energized electrical conductors or circuit parts) states "Capable of being inadvertently touched or approached near than a safe distance by a person. It is applied to electrical conductors or circuit parts that are not suitably guarded, isolated, or insulated."
Is the deadfront a suitable guarding if no energized work is being conducted, or do employees need to follow the approach distances and PPE requirements?
