Unpowered fresh air hose breathing apparatus (FAHBA) with full face mask

Description

  • Fresh air is drawn through a long breathing hose that is secured in a clean environment (e.g. factory, farmyard, roadside), feeding into the face mask
  • Air is drawn in either by the breathing action of the wearer, or with a help of an air blower fitted to the FABA
  • The BA can be cleaned and reused many times, as recommended by the manufacturer
  • FABA has inlet and outlet valves which must be in good condition
  • This BA may be worn continuously for more than one hour
  • 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)
  • Fan assisted BA may be needed for a heavy work rate (heavy manual work requiring a lot of exertion and energy)

Dos

  • Ensure that the air inlet of the hose is securely anchored in clean air
  • Select the right size mask for each wearer
  • 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
  • Fit the straps as recommended
  • Always change or recharge the battery after the recommended period (e.g. four hours, or at the end of the day)

Don'ts

  • Leave the air inlet near contamination sources. The environment can change - e.g. vehicle exhaust, solvent spills
  • Anchor with stones or soil. Use the anchor supplied
  • Store in dirty areas between uses
  • Make DIY modifications to the RPE
  • 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
  • Use FABA without the waist belt
