What are Gas Masks?
Gas masks are tight-fitting devices designed to protect the wearer from exposure to dangerous airborne bacteria, viruses, chemicals and vaporized poisons. Most gas masks seal off the wearer’s nose and mouth to protect the airway, but some models include protective eye goggles and full hoods. Gas masks are not to be confused with oxygen masks or scuba masks, which import fresh air from a closed tank. Gas masks filter the outside air as it exists, without the addition of fresh breathable gases.
