15-24-420 Storage of oils, paints and varnishes.

   Unless otherwise specified in the building provisions of this Code, oils, paints, varnishes and similar fluids having a flashpoint above 200 degrees Fahrenheit, according to the standard tests for flashpoint, shall, if stored in any building used for other purposes, in quantities exceeding ten barrels aggregate, be placed in approved metal tanks, and shall be drawn only by the use of approved pumps or other approved devices. Quantities less than ten barrels aggregate may be stored in barrels, or ordinary tanks, and if drawn on the premises, suitable drip pans shall be provided to catch the drips. Boxes of sawdust shall not be used for the purpose. The premises surrounding such tanks shall be kept clean at all times. Any absorbents used to clean flammable liquid spills shall be approved by a nationally recognized testing laboratory.

(Prior code §  129.1-34)

15-24-430 Outside container storage.

   Closed containers stored outside in the open shall be of a type meeting the regulations of the United States Department of Transportation or as herein required. No more than 40 drums (55 gallon capacity per drum) of Class I flammable liquids shall be stored per pile and the pile shall be located at least 40 feet from the nearest building; except that the pile can be located ten feet from the nearest building located on the same premises and under the same management. No more than 80 drums (55 gallon capacity per drum) of Class II flammable liquids shall be stored per pile and the pile shall be located at least 30 feet from the nearest building; except that, the pile can be located ten feet from the nearest building located on the same premises and under the same management. Provided, however, where closed container drum storage on the premises is for resale only with no use other than repackaging the maximum amount of Class I flammable liquids stored per pile may be not more than 120 drums and not more than 160 drums for Class II flammable liquids. A minimum distance of five feet shall be maintained between all piles of Class I and/or Class II flammable liquids. There shall be a 12-foot wide access road within 200 feet of each container. If equipped with a deluge-type sprinkler system, the size of the piles can be doubled and all safety clearances reduced by one half. All storage shall be located so that runoff due to leakage is not toward any structure.

ARTICLE IV. PIPING, VALVES AND FITTINGS (15-24-440 et seq.)

15-24-440 Piping.

   Where the working pressure is less than 100 pounds, all pipe used in systems for transferring and venting of flammable liquids shall be of the standard full weight, ANSI Schedule ten wrought iron, steel, stainless steel, brass type pipe, Type K copper tube or copper pipe. All pipe shall be connected with standard malleable fittings or welded. Copper tubing shall be connected with flare joints or sweat fittings employing solder having a melting point of 1,000 degrees Fahrenheit or more. Where the working pressure is in the excess of 100 pounds per square inch, extra heavy wrought steel pipe (ASTM Schedule 80) and fittings shall be used. All aboveground piping shall be rigidly supported. Swing joints shall be made with butt or close nipples. Cast iron fittings shall not be permitted. Underwriters' Laboratories, Inc. listed expansion joints or flexible underground pipe connectors not exceeding 24 inches in length shall be permitted. No flexible underground pipe connector shall be connected to any impact check valve or within five feet of any remote pumping dispenser.

(Prior code §  129.1-36; Amend Coun. J. 2-7-96, p. 15463)

15-24-450 Test for piping.

   Test for Pipe. All standard full weight wrought iron, steel, stainless steel, brass type pipe, Type K copper tube or copper pipe and fittings shall be tested hydrostatically utilizing water or air tested when installed to 100 psi. Extra heavy wrought steel pipe (ASTM Schedule 80) and fittings shall be tested hydrostatically utilizing water or air tested when installed to one and one-half times its maximum working pressure. The air test shall be held for ten minutes without any loss of pressure. Suction lines may be tested under a vacuum of not less than 20 inches of mercury. Underground and enclosed tank vent pipes may be tested with said tank equal to tank pressure, and not less than five psi.

(Prior code §  129.1-37)

15-24-460 Depth and cover for piping.

   Depth and Covering for Pipe. All underground pipe shall be surrounded with six inches of fine clean sand and pipe shall be at least one foot below the surface of the ground.

(Prior code §  129.1-38)

15-24-470 Protection against corrosion.

   All piping for flammable liquids, both aboveground and underground where subject to external corrosion, shall be painted or otherwise protected.
