Hello all, I have a question regarding the use of compressed air in our CIP centralized system. We follow BRC standards. We are a seafood plant having both a raw side and a RTE side. All cleaning chemicals are pre diluted and we have various drop lines throughout the plant. The centralized system also has a air line from the compressor to each drop line (point of use). My concern is in my previous position at a different employer, we checked air purity at point of use, primarily air wands in a completely different industry. Is my concern valid to want to have the compressed air tested? It is mixing with the water/chemical and being put directly on product contact surfaces. As for risk assessment I do not have a baseline to assess this risk as air testing has never been conducted here.
