The definition of clean is something each company must decide. Establishing this standard means defining the product quality expectations. It involves evaluating the current or planned condition of equipment, type of facility and air-handling system used, available human resources, and finances. These are factors for establishing realistic criteria, since hospital clean might not be financially feasible or warranted. All cleaning should be performed according to standard operating procedures (SOP) on dates and times determined by a dirt team. Operators should be thoroughly familiar with contamination control rules and procedures, always adhere to those rules and procedures, and report any difficulties. The compressed-air system supplying processed air to the paint booth cannot be overlooked in evaluating potential contamination. Clean rooms are one of the best ways to help eliminate contamination entering the powder application area from outside sources.
