Understanding Breathing Air (BS EN 12021)

Online learning programme

The course will guide you through the breathing air regulations and the provision of breathable air to be used by a person in the execution of a work-related task. A full understanding of standards BS EN 12021 and the legal requirements are vital.

A typical compressed air system, is in many instances the initial generator of air for the provision of breathing air.  Compressed air, however, is not clean as it contains many hazards in the form of contamination. In a typical compressed air system, there are 10 main contaminants that require treatment but please note that this rises to 15 if the compressed air is to be used for breathing air. These will require treatment if the breathing air system is to be used and operated safely.
The provision of suitable air for breathing purposes for operators is the responsibility of the employer. The importance of understanding the need for clean breathing air and the frequency of sampling and testing of its purity (quality) is critical whether you are a employer, supplier, consultant, service provider, or user of breathing air.
