Method and system for providing life-sustaining air to persons entrapped within a burning building

摘要

The present invention provides a method and system for providing air to persons entrapped within a burning structure to sustain life until rescuers arrive. The system advantageously utilizes existing water pipes to feed the air at elevated pressure to the trapped occupants. These persons, upon finding their route of escape blocked by the fire or by smoke, retreat into a predetermined refuge room, a bathroom usually or a washroom, and place wet towels, curtains, blankets, etc. against the door to aid in excluding smoke. The pressurized air being supplied through the pipes into the refuge room advantageously raises the pressure therein and thereby prevents the entry of undue amounts of smoke while at the same time replenishing the breathable air within the room.
