Abstract

An inflatable portable refuge structure includes at least one refuge chamber having a floor, ceiling and a peripheral sidewall and an inner resealable entrance in the peripheral sidewall of the refuge chamber. An airlock chamber having a floor, ceiling and peripheral sidewall is connected to the refuge chamber adjacent the inner resealable entrance such that exiting from the refuge chamber through the inner resealable opening proceeds into the airlock chamber. The airlock chamber further includes an outer resealable entrance in the peripheral sidewall thereof. The refuge chamber and airlock chamber each further include at least one one-way pressure valve, the pressure valves operative to release air from within the chambers in response to increased air pressure within the chambers. An external pressurized air supply source spaced from the refuge structure and connected thereto by an air supply hose supplies uncontaminated air to the refuge chamber thereby inflating the refuge structure. The air supply source continuously supplies pressurized air to the refuge structure such that fresh air enters the refuge chamber and airlock chamber thereby forcing older air out of the chambers through the one-way pressure valves.
