Arc flash personal protective equipment (PPE) is a combination of clothing and safety equipment worn for protection from arc flash and shock hazard by a person performing electrical workPrimarily, arc flash PPE is divided into the following subgroups
The Electrical Arc Flash Hazard Protection Standard mandates the minimum safety rules, design criteria and practices for personnel working within the Electrical Arc Flash Hazard Boundary of electrical systems operating at greater than volts, Ac or DC, to
Of course the arc flash protection level is the most important criteria, so the arc rating (ATPV) as per IEC or the arc protection class as per GS ET However, typically the higher the protection level, the lower the luminous transmittance also called Visible Light Transmission (VLT).

The use of AFDDs now offers an additional level of protection against fire caused by arc faults in final AC circuitsGovernment statistics show that there were more than , fires in England occurring in electrical distribution and other electrical appliances, which suggests considerable room for improvement.
Electrical flashover, or arc flash, is one of the most deadly and least understood hazards of electricity and is prevalent in most industriesIt is widely recognised that the higher the voltage of an electrical power system, the greater the risk for people working on or near energised conductors and equipment.
