General information
- Flow indicators and alarms are needed.
- This BA is designed to provide protection factors of 10, 20 and 40.
- This BA can be cleaned and reused many times, as recommended by the manufacturer.
- It is also suitable for a heavy work rate (heavy manual work requiring a lot of exertion and energy).
- The BA may be worn continuously for more than one hour and may be used in oxygen deficient atmospheres.
- The BA is OK for medium work rate (work involving sustained hand and arm movements, or similar to brisk walking).
- 'Constant flow' means that the manufacturer or user sets the air supply rate. This gives a constant flow rate at the selected air supply pressure.
Do
- Fit the straps as recommended.
- Select the right size mask for each wearer.
- Use only the BA manufacturer's connectors.
- Ensure that an adequate clean air supply is available.
- Fit-testing for each wearer is required when using this RPE for the first time.
- Ensure that the compressed air quality meets the minimum requirements of BSEN12021.
- Ensure that wearers check the RPE fits correctly every time, as recommended by the manufacture.
- Ensure that the air line is never deformed - the wearer's life may be at risk without an adequate air supply.
Don't
- Modify any connector threads.
- Store in dirty areas between uses.
- Make DIY modifications to the RPE.
- Use solvents to clean the mask, straps or hose.
