High quality smoke hoods are generally constructed of heat resistant material like Kapton , and can withstand relatively high temperatures. The most important part of a smoke hood is the filter that provides protection from the toxic byproducts of Combustion . Virtually all smoke hood designs utilize some form of Activated Charcoal filter and Particulate filter to screen out corrosive fumes like Ammonia and Chlorine , as well as acid gases like Hydrogen Chloride and Hydrogen Sulfide . The defining characteristic of an effective smoke hood is the ability to convert deadly Carbon Monoxide to relatively harmless Carbon Dioxide through a Catalytic process. Smoke hoods present on aircraft, also called Protective Breathing Equipment (or PBEs), typically generate oxygen for approximately 30 seconds. The oxygen is kept in a closed circuit, usually thanks to a tight neck seal. A Scrubber system may be present to reduce the levels of Carbon Dioxide , and is breathable for around 20 minutes. When the oxygen supply ends, the hood must be removed to avoid suffocation. EXTERNAL LINKS
