Abstract: A breathing apparatus for providing a source of breathable air in a burning structure for the fire fighters or occupants trapped in the burning structure includes a hollow body member connected to a hollow piercing means for penetrating a wall of the structure. The piercing means provides orifices for receiving breathable air from an interior cavity of the wall. The received breathable air is transferred through a filter into an interior portion of the hollow body member for communication to an outlet port formed on the body member. The outlet port can be further coupled to an air line for breathing the air in a face mask or can be coupled directly to a user's mouth.
