H2S Safety Equipment
Breathing Apparatus
A Breathing Apparatus or BA is an item of safety equipment which allows the wearer to work safely in an IDLH atmosphere by providing air to a sealed mask from a stored container or cylinder. The cylinder can either be carried by the user or stored at a remote location with the air being supplied via an airline.
A BA typically has three main components: a high-pressure tank (e.g. 200bar to 300bar), a pressure regulator, and an inhalation connection (mouthpiece, mouth mask or face mask), connected together and mounted to a carrying frame. Breathing Apparatus UK
