Dive shops that take part in the Divers Clean Air Scheme sign up to a charter that recognises and applies the principles of good compressor management as stated in BS EN 12021 (Respiratory protective devices-Compressed air for breathing apparatus).
This British Standard recommends maximum limits for impurities in cylinder air so, under the scheme, samples of compressed breathing air are tested regularly and the results are displayed prominently to give divers information about the performance of the compressor at the time of testing.
The scheme benefits dive shops and divers by improving confidence in the quality of air supplied. Unsatisfactory results indicate problems with the compressor, enabling dive shops to correct the situation and contribute to the promotion of diver safety.
