Arc flash boundary fold3/8/2024 Note: ASTM F1506 is the primary safety standard for arc flash protective clothing in the United States. Some synthetics are inherently flame-resistant while other clothing may be chemically treated for flame resistance. Flame-resistant clothing is usually made out of cotton, cotton-synthetic blends, synthetics, or leather. Protective clothing includes items such as shirts, pants, coveralls, hoods, jackets, rainwear, and parkas. It is the responsibility of the employer to ensure that workers are sufficiently protected. If employees are working in a potentially dangerous environment where heat or flame hazards are present, it is the responsibility of the employer to ensure that workers are sufficiently protected ( OSHA.

It must be capable of withstanding the application of 14,000 volts at 60 hertz for one minute with no current flow or leakage current in excess of 3.0 milliamperes under dry conditions.Īccording to OSHA, employees must use protective footwear when their feet are exposed to electrical hazards. Related: Hard Hat Classifications and Head Protection BasicsĮlectrical shock-resistant (EH) footwear is manufactured with non-conductive electrical shock-resistant soles and heels. This amount of voltage protection is designated for the head only and is not an indication of the overall voltage protection allocated to the worker. Photo: WikimediaĬlass E Hard Hats are designed to reduce exposure to high voltage conductors and offer dielectric protection up to 20,000 volts (phase to ground). Wearing a hard hat is one of the easiest ways to protect the most important part of your body - the head. OSHA standards mandate that a hard hat must be worn “when working in areas where there is a potential for injury to the head from falling objects.” Hard hats must also be worn in working areas where there is the risk of exposure to electrical conductors that can potentially contact the head. If working where there is a threat of injury to the eyes and face from electrical arc flash, safety glasses and goggles should be used with an Arc Flash Hood, hard hat, and arc-rated face shield with a chin cup. Goggles are intended for eye protection only - they do not provide face protection. Safety glasses for electrical work should be non-conductive, anti-fogging, anti-scratch, and anti-static with 99.9% UV protection. OSHA mandates the use of ANSI Z87.1 certified safety eyewear ( OSHA 1910.335(a)(1)(v)) and also requires employers to provide the eye protection appropriate for the particular hazards involved with the current task. ContentsĮye protection is required whenever there is danger of injury to the eyes or face from arc flash or from flying objects resulting from electrical explosion. This guide provides a general overview of the various PPE that may be necessary for safe electrical work, including insulated gloves or sleeves, face shields, footwear, eye or hearing protection, and other electrical protective equipment. In addition to being properly qualified for the task at hand, personal protective equipment (PPE), including arc flash-rated clothing, can provide additional safeguards against the hazards posed by working around electrical energy. Hundreds of deaths and thousands of injuries occur each year on the job due to electrical shock and arc flash, yet almost all of these tragic events are preventable. Electrical Shock and Arc Flash PPE Overview 897×550 70.3 KBĮlectricity has long been recognized as a serious workplace hazard, exposing employees to electric shock, electrocution, burns, fires, and explosions.
