Abstract
Abstract A combination smoke detector and one or more bags for containing air including a housing having a plurality of compartments, a smoke detector unit being mounted in one compartment and an air-bag member being stored in each of the remaining two contiguous compartments. The storage compartments are covered by a hinged panel that opens to release the bags which drop and hang freely from their respective compartments when the smoke detector is activated. Each air bag is arranged to receive and cover a wearer's head so as to provide breathable air during an escape to safety from a smoke-filled room or building.
