A modular, multi-crew life support system and a method of assembling the system involve a fan to draw in ambient air. The system includes one or more assemblies that produce conditioned air from the ambient air, and a housing to support an oxygen source. The system also includes a port configured as an inlet from the oxygen source to augment the conditioned air, and a duct to disperse a result of augmenting the conditioned air as output air to support two or more occupants of an enclosure.

Disclosed are methods and a safety system implemented within a structure of automatic modification of a rate of filling an air bottle with breathable air in the safety system. In accordance therewith, an air fill charge rate controller device is coupled to the breathable air from a source thereof in the safety system having a fixed piping system installed within the structure for supply of the breathable air across the safety system. A flow rate of the breathable air from the source thereof is detected through a flow sensor associated with the air fill charge rate controller device. In accordance with the detection of the flow rate, a control unit of the air fill charge rate controller device automatically modifies a fill rate at which the air bottle is to be filled with the breathable air.
