ABSTRACT:
An emergency breathing and warning system (100) is disclosed to provide an emergency means of obtaining fresh air for individuals trapped within a building containing noxious fumes or smoke. The emergency breathing and warning system (100) includes flanged conduit (122) which passes through an exterior partition (125) or other structural element to provide access to fresh air external to the building. System (100) includes a first breathing apparatus (104) having a breathing mask (112) coupled to a breathing tube (106). Breathing tube (106) passes through conduit (122) to access the fresh air external to the building. First breathing apparatus (104) includes filter element (108) and coupling (110). Coupling (110) provides a means for providing fresh air to a second breathing apparatus (114) having breathing mask (118) and second breathing tube (116) which is frictionally engaged with coupling (110). Coupling (110) further includes sealing cap (140) for sealing coupling (110) when second breathing apparatus (114) is not in use. Warning device (102) is coupled to breathing tube (106) to provide an external visual indication that the emergency breathing and warning system (100) is in use. Warning device (102) is coupled to first breathing tube (106) by coupling wire (103) to provide a positive deployment and subsequent retraction through conduit (122) by breathing tube (106). A storage container (120) is also provided for maintaining the individual elements of emergency breathing and warning system (100) when system (100) is not in use.
