Method of air filtration for fire fighter emergency smoke inhalation protection |
摘要 |
A method of emergency smoke inhalation protection of fire fighters in imminent life-threatening situations includes configuring a canister containing a filter medium to evidence use. The canister has an opening through which air enters and has a coupling for attachment to the mask of a standard self contained breathing apparatus in place of a connection to an air tank. When so connected, air drawn into the mask passes through the filter medium within said canister. A use-evidencing mechanism is operatively connected to the canister to indicate use of the air filtering system. This mechanism can be non-reusable covers applied over the opening and coupling, or a sealed package containing the air filtering system. Such devices provide an indication of previous use of the filtering system and inhibit a fire fighter from using the system in an unauthorized manner.
