Abstract: A safety system and method of an air distribution system of a mine structure is disclosed. In one embodiment, the air distribution includes a supply unit installed on a particular wall of the first set of walls to facilitate delivery of breathable air from a source of compressed air to an emergency support system of the mine structure, a fill site interior to the mine structure to provide the breathable air to a breathable air apparatus at multiple locations of the mine structure, a secure chamber of the fill site as a safety shield that confines a possible rupture of an over-pressurized breathable air apparatus within the secure chamber, a distribution structure that is compatible with use with compressed air that facilitates dissemination of the breathable air of the source of compressed air to multiple locations of the mine structure.

Abstract: A breathing air replenishment control system for installation on multiple levels in a multiple-level high-rise structure includes a ground level-based air inlet connection remote from the structure for providing a source of compressed air to an air storage subsystem positioned at a first lower level of the structure. A series of air fill control stations are installed at spaced levels in the structure, each station having a compressed air inlet connected to the air storage subsystem. Portable high pressure air storage vessels, suitable for mounting in a fireman's self-contained breathing apparatus (SCBA) are inserted into a pivoted rack/blast container in a station. Each station contains a quick-disconnect for connecting empty vessels and removing compressed air filled vessels from the rack/blast container for remounting on an SCBA.
