Breathing air testing is very important to meet standards. If you have workers using breathing air, the quality of the air must meet BS EN 12021:1998.  This standard covers levels of carbon monoxide, carbon dioxide, oil mist, water vapour and oxygen.  The usual recommendation for breathing air testing is to be carried out every 3 months. Environmental Efficiency can carry out this assessment using specialist equipment.

Breathing Air Testing & BS EN 12021

People who work in environments with poor air quality are often supplied with a hood containing an air supply.  The air supply, often referred to as breathing air, is usually supplied by an air compressor via an airline.


What is breathing air & why does it need to be tested?

Since the airline feeding the workers hood is the only source of air, it is paramount that the air is of good quality.  In compliance with the BS EN 12021 no oil, and limits on carbon dioxide, carbon monoxide, oxygen and water vapour must be found in compressed air used for breathing equipments.

Breathing air is usually generated by an air compressor. Regular breathing air testing and monitoring is essential.

In some cases the air intake for the air compressor can be contaminated, for example by vehicles operating nearby.  On construction sites and other outdoor areas, diesel powered air compressors may be used.  With these present there is a danger that the combustion products may be sucked in. It is therefore very important to meet the breathing air testing BS EN 12021 standards for health and safety.
