Proper authorized use of lighting is critical. Electric lamps (outside of,
but within 20 feet of any spraying
area, and not separated by a partition) shall be totally enclosed to prevent the
falling of hot particles. Electric lamps shall be protected from mechanical injury by
suitable guards or by location. Portable electric lamps shall not be used in any spraying area during spraying operations. If used during cleaning or repairing operations portable electric lamps shall be approved for hazardous Class I locations. All metal parts of spray booths, exhaust ducts, and piping systems conveying flammable or combustible liquids or aerated solids shall be properly electrically grounded in an effective and permanent manner. |
