Arc flash protection hoods completely cover the head, neck and chest to protect against arc flash, heat and shock. They also feature an anti-fog face shield that protects the face and allows good peripheral vision. Arc flash protection hoods are typically made of UltraSoft fabric, which is a cotton and nylon blend. Double-layer hoods are made of fire-resistant Nomex and rayon. They are more durable than single-layer hoods and are used in heavy-duty applications. CarbonX, which does not ignite or burn, is another arc flash protection hood material. CarbonX hoods have high arc ratings and provide a high amount of safety, durability and comfort.
