4500 PSI Breathing Air Compressor

The OHS Code requires an employer to ensure that air used in a self-contained breathing apparatus or an air line respirator, is of a quality that meets the requirements of Table 1 of CSA Standard Z180.1-00, Compressed Breathing Air and Systems, and does not contain a substance in a concentration that exceeds 10 percent of its occupational exposure limit.

The CSA Standard specifies that breathing air samples should be collected and analyzed at least once every six months.
