ABSTRACT:
An assembly installable at an underground mine site for storing breathing apparatuses and for facilitating access to and application of such apparatuses comprises a matrix of storage receptacles closable on a common side by respective spring-loaded hinged doors. An actuating mechanism is provided on an assembly frame for simultaneously releasing a multiplicity of latches locking the doors closed, the actuating mechanism being coupled to a valve for opening the same to permit the passage of air from a pressure source to a perforated tube mounted under a cylindrical roof on top of the compartment matrix. The roof has an opening for guiding a stream of air into a space in front of the storage assembly, thereby increasing the time available for a successful application of the breathing devices in a disaster involving the depletion of the atmospheric oxygen supply or the release of toxic fumes into the work area. An acoustic transducer and a light are provided at the assembly in part for signaling to endangered personnel the location of the storage unit.
