Adopt a Code of Practice
It is strongly advised that where available, certain standards and industry codes of practice are adopted, such as the British Retail Consortium (BRC)/ British Compressed Air Society (BCAS) Food Grade Compressed Air Code of Practice in the United Kingdom.
The Code of Practice provides minimum purity or quality standards for compressed air used in the food & beverage sector.
Regular risk assessment
Many food standards relating to compressed air recognise the need to continuously check and test the system with a close eye on potential risk relating to compressed air contamination entering food production.
In particular, hygiene regulations designed to protect the consumer such as European Regulation 852/2004, support the use of HACCP (Hazard Analysis Critical Control Points) with audits often carried out in line with procedures covered in ISO22000:2005. This international standard requires that hazards which may be reasonably expected to occur within food production, processes and facilities use, are identified and risk assessed.
