Unpowered Fresh Air Hose Breathing Apparatus (FAHBA) With Full Face Mask

General information

  • FAHBA has inlet and outlet valves which must be in good condition.
  • This breathing apparatus (BA) may be worn continuously for more than 1 hour.
  • The BA can be cleaned and reused many times, as recommended by the manufacturer.
  • Air is drawn in either by the breathing action of the wearer, or with the help of an air blower fitted to the FAHBA.
  • Fan assisted BA may be needed for a heavy work rate (heavy manual work requiring a lot of exertion and energy).
  • It may be used in oxygen-deficient atmospheres and is useful for short term work such as work in tanks, trenches and sewers.
  • This BA is adequate for light (seated) and medium work rate (work involving sustained hand and arm movements or similar to brisk walking).
  • Fresh air is drawn through a long breathing hose that is secured in a clean environment, for example factory, farmyard, roadside, feeding into the face mask.


  • Fit the straps as recommended.
  • Select the right size mask for each wearer.
  • Ensure that the air inlet of the hose is securely anchored in clean air.
  • Fit-testing for each wearer is required when using this RPE for the first time.
  • Ensure that wearers check the RPE fits correctly every time, as recommended by the manufacture.
  • Always change or recharge the battery after the recommended period (e.g. 4 hours, or at the end of the day).


  • Store in dirty areas between uses.
  • Use FAHBA without the waist belt.
  • Make DIY modifications to the RPE.
  • Anchor with stones or soil. Use the anchor supplied.
  • Damage or deform the mask or hose when putting it away.
  • Get dirt inside the mask, or use solvents to clean the mask, straps or hose.
  • Leave the air inlet near contamination sources. The environment can change, for example vehicle exhaust, solvent spills.
