Compressed airline breathing apparatus (CABA) with half mask

​​​ ​​

General information

• Flow indicators and alarms are needed.
• This breathing apparatus (BA) is designed to provide protection factors of 10 and 20.
• This BA can be cleaned and reused many times, as recommended by the manufacturer.
• It is 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 BS4275.
• 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
• Make DIY modifications to the RPE
• Store in dirty areas between uses
• Use solvents to clean the mask, straps or hose
• Allow the airline to come into contact with solvents
• Keep working if the airflow rate drops or any warning signals are activated
• Use a light-duty airline hose where there is any potential for crushing by passer-by, etc.
