Abstract
A simple, lightweight, easily deployable mask designed for use in modern fires. The mask substantially covers a wearer's face and includes a peripheral adhesive seal for preventing contaminants from effecting the wearer's visual or respiratory systems. The peripheral seal preferably comprises an adhesive band employing the skin adhesive commonly used in surgical masks. The adhesive band provides for closed attachment of the mask to the brow, the temporal area, cheek, over the jaw and down under the chin. The mask is anchored firmly to the ears of the wearer by resilient straps. Thus attached, the mask seals the eyes, nasal passages and mouth from the toxic external environment. The mask includes an intermediate seal separating the mask into separate visual and respiratory portions. The mask further includes a particulate filter impregnated with MOLECULITE® and one, or more frangible vials filled with perfluorocarbon saturated with oxygen which combine to filter out particulates, absorb toxic chemicals and provide a source of oxygen to the wearer.
