Abstract: Housing (10) of a closed circuit breathing apparatus (200), includes a primary wall (20) covering a component space (30) for receiving breathing components (210) of the closed circuit breathing apparatus (200). A secondary wall (40) covers a device space (50) at least partly inside of the component space (30). The device space (50) is sealed by the secondary wall (40) against the component space (30). The device space (50) receives an electric device (100). The device space (50) includes a device opening (52) to the surrounding of the housing (10). The device opening (52) is for inserting the electric device (100).

Abstract: A respiration system is provided with a container (1) in which, by an exothermic chemical reaction of a reaction material, CO2 is removed from the respiration air or oxygen is generated, and with an indicator of the consumption of the reaction material. The consumption indicator has a predetermined amount (7) of material which can be melted by the reaction heat of the exothermic chemical reaction. The material is kept in thermal contact with the container interior in such a manner that a measurement of the total reaction heat, and thus the consumption of reactive material, can be read from the degree of melting of the meltable material.

Abstract: There is disclosed self-contained breathing apparatus equipment 20 comprising a harness 22, 62 comprising a structural member 26, 28, 64 for supporting or housing a cylinder of breathable gas 40. The equipment comprises a visual alert generator 54 comprising a light source 60, 76 mounted to the structural member, the visual alert generator having a plurality of display modes, a wireless receiver 50 arranged to receive telemetry data transmitted from a central control unit 16, and a control module 52 arranged to receive status data, the status data including the telemetry data. The control module 52 is arranged to control the display mode of the visual alert generator based on the received status data.

Abstract: There is disclosed a harness for breathing apparatus, the harness arranged to support a plurality of cylinders of breathable gas side-by-side. The harness comprises a plurality of longitudinally extending cylinder channels arranged side-by-side, each cylinder channel having a rear wall and open at least partially along its length and arranged to accommodate a cylinder. Adjacent cylinder channels are laterally separated by a longitudinally extending channel side wall that in use is disposed between adjacent cylinders.

Abstract: There is disclosed a harness for breathing apparatus which is arranged to support a plurality of cylinders of breathable gas side-by-side and is arranged to be worn on the back of a wearer. The harness comprises upper and lower longitudinally spaced housings coupled together by a longitudinally extending back member. The upper and lower housings are arranged to retain upper and lower portions of each cylinder respectively.

Abstract: A harness for breathing apparatus, comprising a structural support member 10 having a front for accommodating a gas cylinder and a rear for facing the back of a wearer, and left and right sides. Left and right shoulder straps 110, 120 are disposed towards the left and right sides of the structural support member respectively, and each shoulder strap has a first end attached to an upper portion of the structural support member and a second end attached to a lower portion of the structural support member. A plurality of flexible conduits 140, 150 extend from a lower portion of the structural support member along the structural support member, each to a position on either the left or right shoulder strap. Left and right guide channels 30, 32 extend longitudinally along the structural support member along left and right sides respectively, for accommodating the flexible conduits.
