ABSTRACT:
This invention, consisting of a mask and an air delivery system, provides the individual user an increased level of protection and additional time to evacuate in the case of an emergency situation where the normal environment has been contaminated (i.e. by fire, chemical spill, etc.). The invention provides the evacuating person with a small amount of portable compressed air (approximately a 10 minute supply) for breathing from a small pressurized canister that resembles an aerosol canister. The air is delivered at a pre-set pressure and flow rate through a self-contained regulating system, to a mask through a plastic air supply tube. In addition, the invention also provides the user with protection for the face and eyes by virtue of a clear plastic hood which is attached to the mask. The invention is designed to be inexpensive, light weight and disposable/recyclable and is a single use apparatus.
