I understand that testing of compressed air is a necessary Operational PRP. However, I am unclear about the need to test blown (not compressed) air. The specific situation involves blown air that is used to direct the movement of cut greens on a harvest and packing line. Testing of compressed air is a well established O-PRP; but a client opines that regular filter changes on the blown air intake manifolds are sufficient and testing is not necessary, because the air is not compressed. I'm helping the client to prepare for a GFSI audit, and am wondering if there is a standard response to this condition. Thanks in advance for any advice or info you can give!
