Abstract: An improved oral/nasal mask-hood is provided for protection of individuals in the event of fire or smoke exposure. When attached to a supplemental supply of oxygen the mask-hood also provides hypoxia protection to individuals exposed to decompression as in some aircraft incidents. The mask-hood employs a five stage filtering process for converting toxic atmospheric air to breathable fresh air. The hood covers the wearer's head, neck and shoulder area. A neck seal is provided inside the hood for preventing gases from locating within the hood and irritating the wearer's eyes. A transparent member is located on the hood adjacent the wearer's line of sight to provide visibility during the emergency. The hood-mask device, as assembled, is small enough to retrofit into the space provided for the present decompression mask alone.
