The only way to check that your air supply is fit for breathing is by regular testing. Air used in breathing air supplies is also required to have a dewpoint low enough to prevent condensation and freezing. The levels are summarised in the following table. The requirements detailed in the Standard are summarised as in the table above.

The standard specifies that in all circumstances all contaminants shall be kept to levels below the national occupational exposure limits as defined by the Health and Safety Executive EH Air used in breathing air supplies is also required to have a dewpoint low enough to prevent condensation and freezing.

The levels are summarised in the following table. The requirements stipulate that there should be no free liquid water visible in the breathing air supply.

Generally in cases where the lowest temperature cannot be predicted the pressure dewpoint is specified not to exceed Deg C. The standard specifies that in all circumstances all contaminants shall be kept to levels below the national occupational exposure limits as defined by the Health and Safety Executive EH40 The standard applies to self-contained compressed air breathing apparatus used above and under water SCUBA.

The maximum permissible water content of air at atmospheric pressure is also specified and summarised as 120021. The air quality test report should be reviewed in combination with the compressor and air purifier service and maintenance records to provide a complete assessment of the breathing air installation.

This solution provided BAE Systems with a reliable source of compressed breathing air from a machine which was safe to use in a potentially explosive atmosphere. The requirements detailed in the Standard are summarised as in the table above. Any defects should be remedied before the equipment is used again and a further air test carried out to ensure that the breathing air supplied is now safe. It is vital that the quality of compressed air used in respiratory applications is in accordance with diin required standards to prevent risk to human health and corporate reputation.

When the breathing air is used or stored in an area where the ambient temperature is known the pressure dewpoint has to be at least 5 Deg C below the envisaged lowest temperature.

The standard applies to self-contained compressed air breathing apparatus used above and under water SCUBA. Requirements are specified in the standard for permissible levels of oxygen, lubricants, odour, taste, carbon sn, carbon monoxide and water content in compressed breathing air. Safewell provides a complete process for evaluation and implementation of solutions to purify compressed air in accordance with the prescribed quality standards.

It also applies to systems supplying breathing air via an air line, escape devices and systems supplying synthetic air.

All test records should be retained like other business records eh at least 5 years. Any defects in the equipment or test results should be noted and the equipment should be suitably labelled to record test status. The quality of compressed air used in breathing apparatus is specified in the European Standard EN The volume flow and the quality of the compressed breathing air supply should be tested at least every 3 months or whenever a mobile compressor is moved as the intake air is now being drawn in from a new location.
