A protective head enclosure for emergency use by a user to protect the respiratory tract and eyes from smoke and/or noxious gases and to protect the head from heat and/or toxic substances. The enclosure comprises a head enclosure made of substantially flexible, gas impermeable, heat and fire retardant sheet material, the enclosure having a closed top; a circular, flexible resilient ring disposed on and attached to the enclosure between its top and bottom, the resilient ring being adapted to be twisted into a double cylindrical coil for packing and storage of the enclosure and snapped open into a single circular ring and thereby open the enclosure for use; a closure for closing the bottom of the enclosure about the neck and/or shoulders of a user after the enclosure has been placed over the user's head. The protective head enclosure may be folded compactly and stored in a container or cabinet ready to use by a single motion, quick release.
