Patent ID: 8733355

Claim:
A safety system of a structure, comprising: a supply unit of a structure to facilitate delivery of breathable air from a source of compressed air to an air distribution system of the structure; a valve to prevent leakage of the breathable air from the air distribution system; a fill station interior to the structure to provide the breathable air to at least one breathable air apparatus at multiple locations of the structure; a distribution structure that is compatible for use with the compressed air that facilitates dissemination of the breathable air to the multiple locations of the structure; and an air storage sub-system comprising: a pressure booster; and a driving air source to pneumatically drive a piston of the pressure booster to maintain a pressure of the air distribution system higher than a pressure of the source of compressed air such that the breathable air apparatus is capable of being reliably filled, wherein the driving air source enables the breathable air to be optimally supplied to the structure through allowing the breathable air to be isolated from driving the pressure booster.
