There are many types of arc-rated face shields. Face shields without an arc-rating must not be used. Even though they may look similar, face shields without an arc-rating could melt and severely injure a worker if an arc flash occurred. Eye protection (safety glasses or goggles) must be worn under face shields.
Face shields shall have an arc-rating suitable for the arc flash exposure. Face shields with a wrap-around guarding to protect the face, chin, forehead, ears, and neck area shall be used. Face shields without an arc-rating shall not be used. Eye protection (safety glasses or goggles) shall always be worn under face shields or hoods.
Employees shall wear nonconductive head protection wherever there is a danger of head injury from electric shock or burns due to contact with energized electrical conductors or circuit parts or from flying objects resulting from electrical explosion. Employees shall wear nonconductive protective equipment for the face, neck, and chin whenever there is a danger of injury from exposure to electric arcs or flashes or from flying objects resulting from electrical explosion. If employees use hairnets or beard nets, or both, these items must be arc-rated.
