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.

A swing bed absorption apparatus includes a bed including a bed housing including, an outer surface, an interior chamber, and a flared interior passageway fluidly connecting the interior chamber to an area located outside of the bed. The flared interior passageway includes an opening in the outer surface, a chamber opening at the interior chamber, a first portion located at the opening, the first portion being fluidly connected to the area located outside the bed through the opening, and a flared portion located at the chamber opening, the flared portion being fluidly connected to the interior chamber through the chamber opening. The flared portion connects to the interior chamber at an obtuse angle.

A safety system implemented within a structure includes a source of breathable air, and a fixed piping system to supply the breathable air from the source to each interior region of a number of interior regions across the structure. The fixed piping system is implemented in a ringed architecture including a first portion of the fixed piping system proximate the each interior region and a second portion thereof farther away from the each interior region. In accordance with the ringed architecture, the first portion and the second portion are implemented as a continuous ring with respect to the source of the breathable air such that, even during a compromise of a first sub-portion of the first portion, unaffected by the compromise, the breathable air continues to be supplied to a second sub-portion of the first portion by way of the second portion.

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.
