15-24-020 Definitions.

   (a)   “Closed container” means a container so sealed by means of a lid or other device that neither liquid nor vapor will escape from it at ordinary temperatures.

   (b)   “Container” means any can, bucket, barrel or drum intended for portable use.

   (c)   “Flashpoint of the liquid” means the minimum temperature at which it gives off vapor sufficient to form an ignitable mixture with the air near the surface of the liquid.

   For a liquid which has a viscosity of less than 45 Saybolt Universal Seconds (SUS) at 100 degrees Fahrenheit, does not contain suspended solids, and does not have a tendency to form a surface film while under test, the procedure specified in the Standard Method of Test for Flashpoint by Tag Closed Tester (ASTM D-56-70) shall be used.

   For a liquid which has a viscosity of 45 SUS or more at 100 degrees Fahrenheit, or contains suspended solids, or has a tendency to form a surface film while under test, the Standard Method of Test for Flashpoint by Pensky-Martens Closed Tester (ASTM D-93-71) shall be used, except that the methods specified in Note 1 to Section 1.1 of ASTM D-93-71 may be used for the respective materials specified in the Note.

   For a liquid that is a mixture of compounds that have different volatilities and flashpoints, its flashpoint shall be determined by using the procedure specified in the above paragraphs on the liquid in the form it is shipped. If the flashpoint as determined by this test is 100 degrees Fahrenheit or higher, an additional flashpoint determination shall be run on a sample of the liquid evaporated to 90 percent of its original volume, and the lower value of the two tests shall be considered the flashpoint of the material.

   (d)   Flammable Liquids. All flammable liquids shall be divided into three classes according to flashpoint as follows:

      Class I. Liquids with a vapor pressure less than 40 pounds per square inch absolute at 100 degrees Fahrenheit and a flashpoint below 100 degrees Fahrenheit, 38 degrees centigrade as determined by the herein-required test.

      Class II. Liquids with a vapor pressure less than 40 pounds per square inch absolute at 100 degrees Fahrenheit and a flashpoint above that for Class I and below 140 degrees Fahrenheit, 60 degrees centigrade, as determined by the herein-required test.

      Class III. Liquids with a flashpoint above that for Class II and below 200 degrees Fahrenheit, 93 degrees centigrade. Flammable liquids shall include but not be limited to:

   Class I

      Ether

      Carbon bisulfide

      Gasoline

      Naphtha

      Benzol

      Collodion

      Acetone

      Ethyl alcohol

      Amyl acetate

      Toluol

      Ethyl acetate

      Methyl acetate

      Amyl alcohol

      Turpentine

   Class II

      Kerosene

      Fuel Oil No. 1

   Class III

      Fuel Oil No. 2

      Aniline

      Creosole

      Any fluid, manufactured liquid or fluid commodity, such as paint, varnish or lacquer, dryer or cleaning solution or polishing liquid which contains flammable liquid, shall be classed in accordance with this section according to the flashpoint of the mixture.

      When artificially heated to temperatures equal to or higher than their flashpoints, Class II and III liquids shall be subject to the applicable provisions for Class I liquids. The provisions of this chapter for Class I flammable liquids shall be applied to high flashpoint liquids when heated to temperatures equal to or higher than their flashpoints even though these same liquids would be outside the scope of this chapter when they are not heated.

   (e)   “Process area” shall mean that location where flammable liquids are processed or stored as a part of current production.

   (f)   “Safety can” shall mean a container, not over five-gallon capacity, having a spring closing lid and spout cover, tested and approved by a recognized testing agency.

   (g)   “Anti-syphon valve” shall mean a valve designed to prevent the syphoning of liquid from a tank in the event of an interruption in the discharge pump or pump suction.

(Prior code §  129.1-2; Amend Coun. J. 5-2-95, p. 73)

15-24-030 Warning signs.

   Every building or room or aboveground tank for the use or storage of flammable liquids, shall have the words “Flammable – Keep Fire Away” painted in a conspicuous position on the outside thereof, with letters plainly legible, bright red letters on a white background with letters not less than six inches high and with the principal strokes thereof not less than three-fourths inch in width.

(Prior code §  129.1-3)

15-24-040 No smoking.

   No person shall smoke in that part of any premises where flammable liquids are stored, handled or used.

(Prior code §  129.1-4)

15-24-050 Unattended coin-operated dispensing devices.

   The installation and use of unattended coin- operated or self-service dispensing devices for Class I liquids is prohibited except as permitted by regulations issued by the commissioner of business affairs and consumer protection.

(Prior code § 129.1-4.1; Amend Coun. J. 11-19-08, p. 47220, Art. V, § 5)

15-24-060 Heating.

   Heating in rooms and buildings used for the storage and handling of Class I flammable liquids shall be by steam, hot water or approved electrical heaters installed in accordance with Title 14E. Fire walls shall surround all boilerrooms, furnace rooms and other rooms containing exposed fire, electric dynamos, motors, switches or other spark-producing devices.

(Prior code § 129.1-5; Amend Coun. J. 9-6-17, p. 55278, Art. II, § 52)

15-24-070 Drains.

   There shall be no floor drains or other connections to the city sewer system from a tank or tank manhole or any room or compartment in which flammable liquids are stored or used, except where fuel oil is stored having a capacity of 550 gallons or less.

(Prior code §  129.1-5.1)

15-24-080 Use for illumination prohibited.

   No system of artificial lighting and no lamp, torch or other device for illumination, which employs any Class I flammable liquid shall be installed in any new or existing building.
