On the other hand, high levels of Arc Flash Clothing are extremely bulky, and may restrict vision and movement, increasing the chance of an accident as well as increasing work time and difficulty. This is because too little Arc Flash Clothing exposes a worker to potentially lethal injury. NFPA 70E Table 130.7 lists the appropriate level of PPE for use when encountering harzardous electrical areas.ĭeciding on the appropriate level of Arc Flash Clothing is very important. Arc flash, however, can take place and result in injury or death even when there are no energized electrical parts. PPE Category 4 currently represents the highest level of compliance, with arc ratings going above 40 cal/cm2.NFPA 70E requires that all electrical workers who operate within the Flash Protection Boundary must wear Arc Flash Clothing and understand arc flash clothing requirements. PPE Category 4: Minimum Arc Rating 40 cal/cm 2 AR jackets, parkas, rainwear, and hard hat liners as needed.AR rubber insulating gloves and leather protectors.AR flash suit jacket and pants or coveralls with a 25 cal/cm 2 minimum arc rating.Flash suit hoods are a standard requirement as well as AR heavy-duty insulated rubber gloves and leather protectors for the gloves PPE Category 3 protection requires additional layers of protective clothing. PPE Category 3: Minimum Arc Rating 25 cal/cm 2 AR jackets, parkas, rainwear, and hard had liners as needed.AR face shield or flash suit hood with a sock hood or balaclava.AR long-sleeved shirt and pants or coveralls with an 8 cal/cm 2 minimum arc rating.Since Category 2 PPE is comparable in comfort to Category 1, it makes more sense to choose Category 2 clothing. In many situations, companies that require Category 1 PPE opt for Category 2 PPE so that they meet both requirements. PPE Category 2 likely requires only a single layer of AR PPE. PPE Category 2: Minimum Arc Rating 8 cal/cm 2 AR jackets, rainwear, hard had liners, and parkas as needed.Arc flash suit hood or AR face shield with wraparound guarding.Arc-Rated (AR) long-sleeved shirt and pants or bodysuit with a 4 cal/cm 2 minimum arc rating.This category only requires a single layer of PPE that typically includes the following: PPE Category 1 is the lowest level that requires arc-rated PPE.

Generally, a higher rating means it requires higher levels of protection. The type of PPE required depends on the incident energy level, or arc rating, within a work area. All PPE worn in these environments must adhere to the standards set forth by NFPA 70E to ensure optimal protection from potential electrical arc flashes. Individuals that work in environments with various electrical hazards must be adequately trained in the use and application of electrical PPE, such as hard hats, ear protectors, face shields, insulated rubber gloves, and more.
