What type of face shields should I choose for electric arc protection?
Electrical workers, linesmen and electricians working with high voltage connections are sometimes exposed to the sudden release of energy that occurs during an electrical arc. This is a very dangerous condition, that can result in serious burns and death. There has long been requirements established for safety clothing to be used by these workers, but from January 1, 2003, it is required that electrical workers use face protection meeting similar requirements. The National Fire Protection Association’s standard 70E-2000 establishes Hazard or Risk categories, as shown in the table below. Elvex ARC-Shields are suitable for use in hazard/risk categories 1 and 2. The minimum Arc Thermal Performance Value (ATPV) has been established to be 5 cal/cm and 8 cal/cm for these two risk categories. (Cal/cm stands for calories per square centimeter).
