Unpowered FAHBA with full face mask - Healthy Working Lives

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 one 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 a 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. four 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.
