Quality of compressed breathing air
Compressed breathing air protects workers engaged in tasks such as sandblasting, spray painting, storage vessel cleaning and similar activities where repeated exposure to hazardous chemical substances and / or a lack of oxygen can pose a health risk.
Compressed breathing air should be tested to determine if any contaminants are present at levels that may be detrimental to the health of the user. Excessive levels of CO, CO2, oil and water mist within compressed breathing air can cause the user to become lightheaded, nauseous and dizzy.
High levels of contaminants in the compressed breathing air can be caused by saturated filters or incorrect compressor servicing. These factors would not necessarily be identified in the initial stages of use as it is difficult to detect CO or CO2, which do not give off any taste or odour, adding emphasis to the importance of testing compressed breathing air.
OCSA Occupational Hygiene and Environmental Services can assist you with tests in order to evaluate the quality of compressed breathing air against the requirements provided in the Regulations for Hazardous Chemical Substances, OHSAct (85 of 1993) and South African National Standard (SANS) 277: 2004, Respiratory protective devices, compressed air for breathing apparatus, with regards to the following:
- Oil lubricants.
- Odour and taste.
- Carbon dioxide.
- Carbon monoxide.
- Water content.
We provide you with detailed report on the quality of your compressed breathing air.
