ABSTRACT:
A protective enclosure fabricated from a clear, flexible, plastic material that, in the event of an emergency, is easily positionable over the head and upper body of a wearer to protect the wearer from the adverse effects of a contaminated environment, such as that filled with smoke or similar noxious fumes. The top of the enclosure is sealed by a reinforced, relatively stiff closure member. Accordingly, an airspace containing a reserve air supply from which the wearer may breathe is created around the wearer's head. The bottom of the enclosure contains a fastener by which the enclosure may be securely tightened around the waist of the wearer. Each side of the enclosure includes an arm port through which the wearer's arms may extend. The arm ports are interfaced with an elastic material which is adapted to form an airtight seal around the wearer's arms when the arms are inserted therethrough. The protective enclosure may optionally have one or more filtering assemblies established therein through which the wearer may breathe in the event that the reserve air supply becomes exhausted. Hence, a relatively low cost, reliable, and easily operable protective enclosure is provided that can be folded and conveniently placed in a pouch for either storage or distribution, such as to the occupants of a high-rise building for use in the event of fire, or similar catastrophe.
