Abstract:

Several recent jet transport accidents have focused the attention of the aviation industry upon smoke and toxic gases as causal factors of passenger incapacitation and failure to evacuate aircraft before fire and heat render the environment uninhabitable. If it were possible to provide passengers with a short duration supply of breathing air sufficient to maintain the passengers' mobility and allow completion of aircraft evacuation, survival would be enhanced.

Simple, light-weight, bag-shaped hoods incorporating a neck seal were fabricated of a thin pliable, high-temperature, transparent, polyimide plastic film. Polyimide film has no melting point but reportedly chars at 1500 deg F. In a more advanced design, thin transparent metallic coatings were applied to the polyimide film in order to reflect up to 90% of the radiant heat.

Upon exposure to a specific infra-red heat flux, facial skin temperatures of 114-115 F were recorded on twelve human subjects wearing the non-metalized hood. Under identical conditions, skin temperatures of the same subjects wearing the metalized hood did not exceed 99 F. Capability of the hood to provide short term and extended protection from smoke and flame inhalation in a fire environment is discussed.
