We have a paint booth (building) and are looking to extend it. The code is clear regarding Classifications around the doors. This is a down draft ventilated building and the air is filtered then returns to atmosphere out the openings on the side of the building. I can't find what the classification bubble would be around the exhaust openings, but surely there is one.
Any ideas?
