(a) Artificial lighting in finishing rooms, spray rooms, spray booths and dipping rooms shall be by electricity only. Except as provided in subsection (b) hereof, all electric wiring and equipment in rooms where flammable finishing materials are applied shall be in conformity with the provisions of Chapter 3161, governing installations in hazardous locations.
(b) Where spraying is done in properly arranged and ventilated spray booths, portions of the finishing room more than twenty (20) feet from such booths need not be considered as hazardous locations in determining requirements for electrical installations unless such portions are so classified as the result of other operations. In the area within twenty (20) feet of properly arranged and ventilated spray booths, provisions governing electrical installations in hazardous locations may be modified to allow motors of the totally enclosed type or of the open-induction type having no brushes, make or break contacts, collects or other arcing or sparking parts, and to allow lamps of the enclosed vapor-tight type.
