The instant invention is a respiratory system for use on aircraft or similar compartments to temporarily prevent asphyxiation and suffocation due to the presence of smoke, toxic gases and/or noxious gases resulting from aircraft fire or similar such. The respiratory system consists of a small dropout package containing a protective hood for deployment to enclose the head of the passenger to improve the passenger's vision in the smoke, a protective breathing mask for enclosing the mouth and nose of the passenger in order to provide breathable air and a dual air supply system. The respiratory system provides a connection to a fresh, breathable air supply from the aircraft's emergency air source and provides a chemical air purifier preferably including a wet scrubbing system for purifing cabin air of contaminants to supply additional breathable air. The respiratory system is disengageable from the aircraft's emergency air source for evacuation. |
