(3) Use of high-volume, low-pressure (HVLP) spray guns when: (A) spray-coating operations do not involve motor vehicles or motor vehicle components; (B) the gun cup capacity is 8 fluid ounces or less; (C) the spray gun is used to spray-coat less than 9 square feet per day per facility; (D) coatings are purchased in containers of 1 quart or less; and (E) spray-coating is allowed by fire department, fire marshal, or other government agency requirements. (4) Use of air-brush spray equipment with 0.5 to 2.0 CFM airflow and a maximum cup capacity of 2 fluid ounces, provided that persons claiming exemption from Section 9.16(e) of this regulation register with the Agency in accordance with Article 5 of this regulation and provide a copy of the current Agency registration document to each new customer before starting work at a site; (5) Use of hand-held aerosol spray cans with a capacity of 1 quart or less; or (6) Indoor application of automotive undercoating materials using organic solvents having a flash point in excess of 100°F. (c) General Requirements for Indoor Spray-Coating Operations.
