Are all spray-applied coatings applied in an enclosed ventilated spray booth or preparation station?
Inspector will perform visual inspection to confirm that spray booths and prep stations, where coatings are applied for full vehicles, are fully enclosed with a full roof, four complete walls or side curtains and an exhaust fan.
Spray booths or prep stations where coatings are applied on vehicle components only, i.e. not full vehicle, must be fully enclosed with a full roof and at least three complete walls or side curtains and an exhaust fan.
IF NO, SKIP to Question 6
If yes, is the spray booth and/or station fitted with a particle filter(s) on the exhaust?
Inspector will perform visual inspection of pipe and filter as well as ask the facility if station is fitted with a particle filter(s) on the exhaust.
NOTE: May see wall fan and small box with filter.
If the facility uses a spray booth or prepstation, is it fitted with a type of filter technology or system that has been demonstrated to achieve at least 98-percent capture of paint overspray (this could include polyester fiber or fiberglass filters)?
Inspector will ask for any documentation, e.g. on filter package or from distributor, of the filter efficiency.
NOTE: Visual inspection alone may be too difficult to determine compliance.
Is all paint spray gun cleaning done with a fully enclosed spray gun washer or in a manner that avoids creating an atomized mist or spray of gun cleaning solvent?
Inspector will ask facility to demonstrate how guns are cleaned.
Acceptable methods of spray gun cleaning include: Hand cleaning of parts of the disassembled gun in a container of solvent; flushing solvent through the gun without atomizing the solvent and paint residue, by using a fully enclosed spray gun washer, or by a combination of these non-atomizing methods.
NOTE: Spraying into the air is an unacceptable cleaning method. Also, any waste solvents that are collected must be kept in a closed container to avoid release/evaporation to the air.
