A gas containment and supply apparatus is described consisting of a gas reservoir vessel (1) capable of pressurised gas containment fitted with a gas supply aperture (8) provided with supply means connectable to the gas supply aperture to provide for supply of the gas and control means to control the rate of supply of the gas, in which the gas reservoir is a toroidal pressure vessel comprising a metallic toroidal shell (2) having wound on its surface a tensile load bearing layer of high tensile strength non-metallic fiber (4), the fiber being aligned in a substantially meridional direction on the toroidal shell. Human portable breathing apparatus is described utilising the above.

1. A gas containment and supply apparatus comprising:a gas reservoir vessel capable of pressurized gas containment fitted with a gas supply aperture, supply means connectable to the gas supply aperture at a first end to provide for supply of the gas through a second end, and control means to control the rate of supply of the gas, wherein the gas reservoir vessel is a toroidal pressure vessel comprising a metallic toroidal shell having wound on the surface thereof a tensile load bearing layer of high tensile strength polymeric fibre, the fibre being aligned in a substantially meridianal direction on the toroidal shell and being free of any matrix material for at least a substantial part of its winding depth.
