Refuge Chamber for Tunneling
Refuge chamber
When escaping from a hazardous area, a person may tire and require and area to rest and recuperate to continue the escape. A refuge chamber that is activated via an alarm schedule during an emergency, can serve as an intermediate station for escapees for up to eight hours. In addition to communication facilities the affected individuals – if the chamber is suitably configured – also have access to protective equipment to allow them to continue.
