A room or enclosure specifically designed to isolate overspray and fumes resulting from the application of coatings by spray. The booth should be constructed from metal or other fireproof material, and all electrical fittings should be explosion-proof. There are two types of spray booths: the dry type or water wash type. A dry spray booth uses filters, while a water wash spray booth uses water spray. It is typically used to coat small fabricated items or test panels.
