Just looking for a bit of help - and here's the situation.
I work for a large-scale bakery. We have a portable diesel powered power washer in the event our main washer breaks down. When needed, we currently run the diesel one outside (We do monitor the water for Coliforms/TPC, no issues there) and run the line back into the building.
However, one of the managers has recently challenged whether or not we must use it outside if there is no production going on. (During cleaning on the weekends - presumably to allow for better access and pressure in areas of the plant far away from it).
We (Quality Personnel) are quite against it for a few reasons. 1) Fumes for worker comfort and safety (We do have a 3 story tall fairly expansive building so it likely would not be very concentrated) 2) We store ingredients in all different areas of the plant (including adjacent to production lines), and are concerned about the smells permeating the packaging and possibly causing dry ingredients to get off flavors. 3) Potential of fumes/residues settling in or on equipment. (As we have large ovens, fryers, etc.)
However the question has been raised if we can come with some kind of documentation/proof/standard/rule supporting why we do not want diesel power being used in the food processing area at any time.
We've found some documentation from OSHA indicating that Diesel fumes are a potential health hazard. I haven't had much luck beyond that yet, though I do recall an audit in the past (Cook and Thurber maybe?) that stated specifically forklifts should not be gasoline powered in the food processing area. (But haven't had luck finding that.) My hope is maybe someone can help with some kind of reference to regulatory or 3rd party standards. Or if there are perhaps other thoughts, as well.
Very much appreciated in advance!
