15-24-540 Reclaiming systems.

   Nothing in the building provisions of this Code shall be construed prohibiting the use of flammable liquid reclaimers or recovery systems, the capacity of which is less than ten gallons per hour and which equipment shall not heat the liquid above 500 degrees Fahrenheit, and which shall have no open flame. Such devices shall be arranged so that all gasoline or kerosene and similar vapor which are removed from the oil, shall be condensed and collected in a closed vaportight container.

   “Paint spraying room” means a room designed, intended or used for the purpose of spraying more than ten gallons of paints, varnish, lacquer, enamel or other such volatile or flammable liquid or liquid containing any volatile flammable substance in solution or suspension during any 24-hour period; without use of an approved spray booth.

   “Paint spraying” means the application of flammable or combustible paint, varnish, lacquer, enamel, stain or other such volatile or flammable liquid, or liquid containing any volatile flammable substance in solution or suspension applied as a spray by whatever means, in continuous or intermittent processes, where more than one gallon of such liquid is used in any 24-hour period.

   “Spray area” means any area in which dangerous quantities of flammable vapors or combustible residues, dusts or deposits are present due to the operation of spraying processes. The spray area shall include:

      (a)   The interior of spray booths;

      (b)   The interior of ducts exhausting from spraying processes;

      (c)   Any area in the direct path of spray or any area containing dangerous quantities of air- suspended combustible residue, dust, deposits, spray or vapor as a result of spraying operations.

   “Spray booth” means a specially designed enclosure constructed of noncombustible materials and otherwise complying with the requirements of this chapter and other applicable sections of this Code, in which paint-spraying operations are carried on.

(Prior code §  129.1-47)

15-24-560 Spraying restrictions.

   Spraying. Paint-spraying operations shall not be permitted in any institutional building. Paint-spraying operations shall not be permitted in any assembly, school or multiple-dwelling building except in a room designed for the purpose, protected with an approved system of automatic sprinklers and separated vertically and horizontally from other parts of the building by construction having not less than two-hour fire-resistive rating.

(Prior code §  129.1-48)

15-24-570 Paint mixing, spraying and japanning room.

   Every paint-mixing room, paint-spraying room and every room containing a japanning dip tank, vat or japanning oven located in any building other than a building of Type IA, IB or IC construction which is also equipped throughout with a standard system of automatic sprinklers, shall be constructed in accordance with the requirements of this section. Any such room, with a floor area of not more than 600 square feet, shall have a floor of any type of construction permitted for the building in which located and shall have both walls and ceiling of one-hour fire-resistive construction. Any such room, with a floor area of more than 600 square feet and not more than 1,200 square feet, may have a floor of any type of construction permitted for the building in which located, and shall have both walls and ceiling of two-hour fire-resistive construction. Any such room with a floor area of more than 1,200 feet, shall be separated from every other part of the building by not less than four-hour fire-resistive construction. No such rooms shall have any opening except a doorway or doorways between such room and any part of the building. Every doorway through any such wall or separation shall be provided with a door of the character required by Chapter 15-12 for fire doors.

   A spray booth shall be required when paint- spraying operations are carried on in any building when using more than one gallon of previously defined liquid in any 24-hour period except in those cases where the physical size of the materials being sprayed, such as in structural steel shop coating and similar operations, makes it impractical to conduct such operations within a spray booth. A paint-spraying room shall be required when the liquids used, as defined in Section 15-24-550, exceed ten gallons in any 24-hour period unless conducted in an approved booth. Nothing in this section shall be construed as prohibiting more than one such spray booth in any paint-mixing room.
