Self-Contained Breathing Apparatus (SCBA)
Self-Contained Breathing Apparatus ( SCBA) is a device worn by the Firefighter or rescue workers in an oxygen deficient environment. They provide breathable air in conditions such as in confined space or smoke filled area where there is acute shortage of breathable air. The SCBA sets are with filter compressed normal atmospheric air.
A Self-Contained Breathing Apparatus typically has three main components — Cylinder, Back plate and Face mask. The cylinder consists of air at high pressure. The back plate consists of the pneumatic system, harness, high and low pressure hose, demand valve, warning whistle. The face mask is what provides air to the wearer..
The Sigma 2 Type 2 is specifically designed as a Marine / Industrial Fire Fighting SCBA, but is also suitable for providing respiratory protection in any IDLH environment to carry out interior firefighting and hold the blazing fire under control until the fire brigade arrives.
