ABSTRACT:
A protective hood for protecting flight crewmembers from chemical-biological agents having a nonpermeable covering which fits over the helmet and extends over the shoulders of the flight suit. A rigid transparent lens is sealed to the helmet covering and is positioned in front of the flight helmet visor assembly. A hose enclosure member is secured to the helmet covering and is closed around the oxygen hose with hook and loop fasteners. Hook and loop fasteners also provide a closure for the front of the helmet covering and shoulder covering members. Openings, sealed with pocket members are provided on the side of the protective hood to permit adjustment of the visor. An air nozzle is provided under the hood to provide flushing of chemical-biological agents as well as cooling and evaporative action in the facial region.
