The device is rendered into the operative condition by opening the envelope which converts to a head cap for covering head and eyes of the wearer and extending the face mask out of the envelope whereby the mask extends downwardly from the cap over the nose and mouth of the wearer to afford protection against smoke and noxious fume inhalation.
