Specifically designed to protect health care professionals from residual chemical/biological/radiological agents when they are performing first responder duties during homeland security or terrorist situations. Weighing less than six pounds, the system features a lightweight, chemical-resistant Tychem SL hood and belt-mounted blower with two HC CBA/RCA canisters. The canisters contain a pleated high-efficiency (P-100) filter to remove aerosols, radionuclides, and solid particulates, as well as an impregnated, activated carbon bed to adsorb (filter out) gases and vapors. The carbon bed is the same as used in military canisters and is effective against mustard (HD), Sarin (GB), DMMP (a Sarin simulant), HCN and CK. Approved for High Efficiency, Chlorine, Sulfur Dioxide, Hydrogen Chloride, Hydrogen Fluoride and Hydrogen Sulfide (escape only).

The hood, which weighs approximately eight ounces, has a fully adjustable suspension and soft fabric collar for extended-wear comfort. Positive pressure inside the hood keeps contaminants out and eliminates the need for fit testing, so the comfortable, easy-to-don hood can be worn over eyeglasses, long hair and beards. Front and rear bibs provide neck-opening protection without restricting arm movement. A wraparound lens helps to minimize claustrophobia and provides excellent visibility. For efficient training and savings on batteries, a rechargeable NiCd battery can be substituted for the lithium battery, which provides a 10-year shelf life and four hours of wear time.
