What is the function of regulator valve in BA set?

What is the function of regulator valve in BA set? Correct Answer All of these

Explanation:

  • A compressed air breathing apparatus (CABA) is a type of respiratory protection equipment that provides breathable air from cylinders containing compressed air.
  • It is used by firefighters, rescue workers, and others who operate in environments where air quality may present an immediate threat to human health and safety.
  • A compressed air breathing apparatus is also known as self-contained breathing apparatus (SCBA).
  • CABA consists of the following:
    1. A single or a pair of high-pressure cylinders made of steel, aluminum or carbon-fiber composite (200-300 bars)
    2. One pressure regulator, which has to perform
      1. Increases pressure from low to high
      2. Decreases pressure from high to low
      3. Maintains same pressure
    3. Face-seal mask or facepiece, mouthpiece and connecting supply pipes
    4. A carrying frame or pack
  • CABAs can include one or two cylinders, which can provide breathable air for 30 to 45 minutes.
