Self-Contained Breathing Apparatus (SCBA) or Compressed Air Breathing Apparatus (CABA) is used for entry into a known hazardous environment. One user we will all recognise is the Fire Services, who use SCBA to enter areas where smoke and noxious gases are present, but SCBA is used in many entries where there is a toxic gas, asphyxiate or oxygen deficient environment. A SCBA set consists of 3 main components – a cylinder of compressed air, a back-plate that holds the cylinder and reduces the air from high pressure (200-300bar) to medium pressure (5-11 bar) and this in turn supplies a face mask. Self-Contained BA gives autonomy to the user, meaning that they can move around freely as opposed to being attached to an airline. However, the disadvantages are that the cylinder has a relatively short supply time, for example a 9.0L 200 bar cylinder giving a usage time of 35 minutes, and also the cylinder means an increased size and therefore can hinder ease of movement through tight spaces. There are many different sizes of cylinders which can improve duration or manoeuvrability, but these limitations will still remain to some extent.

 

GLOBAL SUPLLY BA SET stands for Breathing Apparatus Set, which is a device used by firefighters and other rescue personnel to provide clean air to breathe in hazardous environments. It consists of several parts, including: Cylinder: The cylinder contains compressed air or oxygen that is used to provide breathable air to the user
