Abstract
The individual equipment for use when taking action in a noxious atmosphere comprises a pressure suit having a flexible garment (10) and a helmet (12) provided with a transparent visor and including a self-contained breathing apparatus for supplying breathing gas from a gas supply. The face is separated from the garment by a neck gasket (16). The supply (24) is connected to a breathing circuit that opens out into the helmet via a regulator (48) to maintain the volume around the face at a pressure higher than that in the garment. The equipment also includes a face mask (52) having a valve for breathing in from the helmet and pipework for breathing out directly to the outside via rated non-return means.
