• Protective equipment such as shields, barrier and insulating materials may be used to protect workers from electric shock and arc flash and blast.

The Occupational Safety and Health Administration (OSHA) requires employees to:

• Wear protective equipment for the eyes or face wherever there is danger of injury to the eyes or face from electric arcs or flashes or from flying objects resulting from electrical explosion.
• Use protective shields, protective barriers, or insulating materials to protect themselves from shock, burns, or other electrically related injuries while that employee is working near exposed energized parts which might be accidentally contacted or where dangerous electric heating or arcing might occur. When normally enclosed live parts are exposed for maintenance or repair, they must be guarded to protect unqualified persons from contact with the live parts.
