15-26-020 Definitions.

   For purposes of this chapter, the following definitions apply.

   Fume or Flammable Compressed Gas Building, Rooms and Gases.

      (a)   “Fume or flammable compressed gas building” means a building, or part of a building, designed, intended or used for the purpose of manufacturing, compressing or storing any fume hazard gas or any flammable compressed gas, either at a pressure of more than 15 pounds per square inch or in a quantity of more than 2,500 cubic feet.

      (b)   “Fume or flammable compressed gas room” means a room designed, intended or used for any of the purposes described under subsection (a) of this section and which is located in a building other than a fume or flammable compressed gas building.

      (c)   “Fume hazard gases” means ammonia gas, chlorine gas, phosgene gas, sulphur dioxide gas, chlororipicrin gas, cyanogen gas, hydrogen cyanide gas, nitrogen peroxide gas and other gas which has an equal or greater danger to life; and any other gas which, as determined by the committee on standards and tests, is in fact a poisonous irritant or corrosive gas and is not susceptible to fire or explosion, shall each be defined as a fume hazard gas.

      (d)   Flammable compressed gases, acetylene gas, ammonia gas, ether gas, ethyl chloride gas, ethylene gas, liquefied hydrocarbon gases, liquefied petroleum gases, hydrogen gas, illuminating gas, methyl chloride gas and any other gas which is a poisonous, irritant or corrosive gas and is also a gas susceptible to explosion under any condition or is not a poisonous, irritant or corrosive gas but is a gas susceptible to burning under any condition shall each be defined as a flammable compressed gas.

   Fume or Flammable Compressed Gas. No sprinkler system shall be required for any fume or flammable compressed gas building of Type IA, IB or IC construction, nor for any room intended for the storage and use of chlorine gas for no purpose other than the operation of a water purification plant or refrigerating unit, nor for any unit of noncombustible construction used exclusively for the production of manufactured gas.

   The following definitions shall apply to sections regulating liquefied petroleum gas only:

      1.   “Containers” means all vessels, such as tanks, cylinders or drums used for transportation or storing of liquefied petroleum gas.

      2.   “Capacity of container” means the amount of liquefied petroleum gas that a container will hold. For Interstate Commerce Commission or Department of Transportation approved containers, this is expressed in pounds of liquefied petroleum gas. For American Society of Mechanical Engineers approved containers, this is expressed in gallons of water capacity.

      3.   “Liquefied petroleum gas” means and includes any material which is composed predominately of any of the following hydrocarbons, or mixtures of them: propane, propylene, butane (normal butane or isobutane) and butylenes.

      4.   “Excess flow valve” means a valve intended to prevent a flow rate greater than the maximum preset flow rate.

      5.   “Filling density” means the ratio of the weight of gas in a container to the weight of water the container will hold at 60 degrees Fahrenheit expressed as a percentage.

      6.   “Safety relief valve” means a valve intended to open upon buildup of excess pressure in the container.

      7.   “Vaporizer” means a device intended to change liquefied petroleum gas from a liquid state to a gaseous state.

      8.   “Used” or “in use” means connected to a system for use.
