The risks of non-compliance.
The EU Directive which applies to the quality of breathable compressed air now imposes a legal obligation on any person or firm supplying air for breathing purposes to test the air quality in compliance with the standard EN12021:1998.
The regulation which gave force to the directive is a statutory instrument 1992/3139. This has been in force since June 1995, although the standard EN12021 only came into force in June 1999.The Trading Standards Department of the Local Authority are tasked with the implementation of this standard and failure to comply could result in prosecution. In the event of any incident it would involve an investigation by the Health & Safety Executive and almost certainly result in litigation if it were found that there had been non-compliance with the essential requirements of the Directive.
