				container will hold. One pound H20=27.737 cubic inches at 60 degrees F. For
				determining the water capacity of the tank in pounds, the weight of a gallon
				(231 cubic inches) of water at 60 degrees F in air shall be 8.32828
				pounds.
(14) "Filling volume" is
				defined as the percent ratio of the liquid in a container to the volume of the
				container.
(15) "Free vented" as
				used means the system is permanently open to the atmosphere. No shutoff or
				check valve is allowed in such opening.
(16) "Gas" means anhydrous ammonia in either
				the gaseous or liquefied state.
(17) "Gas mask" means a gas mask approved by
				the Bureau of Mines (30CFR Part II, Section 14-f).
(18) "Hold-down devices" refers to chains or
				metal straps or cables.
(19) "Hold
				to a minimum" means the product should be loaded in anticipation of sale into
				the nurse tanks and delivered to the consumer for use without being stored in
				nurse tanks waiting for a consumer order.
(20) "Hydrostatic relief valve" refers to an
				automatic pressure activated valve for liquid service characterized by throttle
				or slow weep opening (non-pop off action).
(21) "Implement of husbandry" means a farm
				wagon-type tank vehicle of not over 2000 gallons capacity, used as a field
				storage nurse tank supplying the anhydrous ammonia to a field applicator, and
				moved on highways only for transporting anhydrous ammonia from a local source
				of supply to farms or fields or from one farm or field to another.
(22) "Institutional occupancy" is a location
				where people may be unable to vacate voluntarily and shall be deemed to include
				nursing homes, hospitals, jails, and schools.
(23) "Material suitable for use" includes
				iron, steel and certain non-ferrous alloys which are compatible for use in
				anhydrous ammonia service. Copper, brass, zinc and certain alloys, especially
				those containing copper, are not suitable for anhydrous ammonia
				service.
(24) "Nitrogen fertilizer
				solutions" refers to compounds (ammonium nitrate, urea, sodium nitrate, and
				other nitrogen carriers) formed by the combination of free ammonia and water
				with or without other nitrogen salts. Nitrogen fertilizer solutions includes
				all liquid containing more than 2 percent free ammonia and/or having 5 psig. It
				does not include material containing over 1 percent of phosphorous and/or
				potassium which is used as plant food. The term "nitrogen fertilizer solution"
				should be substituted in lieu of the term "anhydrous ammonia" where it appears
				in these definitions for references made in rules specified in ARM
				4.12.701 for rules specifically
				pertaining to nitrogen fertilizer solutions.
(25) "Pressure vented" is a system equipped
				with a pressure relief valve or a combination pressure-vacuum relief
				valve.
(26) "Private assembly" is a
				location where people gather together but is not generally open to the
				public.
(27) "Psig" and "Psia"
				means pounds per square inch gauge and pounds per square inch absolute,
				respectively.
(28) "Public
				assembly" is a location that is generally open to the public and where people
				gather together, including but not limited to, churches, public halls,
				libraries, clubs and businesses.
(29) "Qualified attendant" means a person who
				has a knowledge of the characteristics of anhydrous ammonia, its safe handling,
				safety rules for transfer and application, and has completed an anhydrous
				ammonia training program conducted by the department or an equivalent training
				program approved by the department.
(30) "Repair" refers to the work necessary to
				restore a container or system to a safe and satisfactory operating condition
				provided that in all cases the container or system design shall continue to
				comply with the requirements of this standard, or the standard in effect at the
				time of installation, that special service requirements do not restrict such
				work and the basic design concept of the system is not altered.
(31) "Safety relief valve" or "pop off valve"
				is an automatic pressure activated valve for vapor service characterized by pop
				action upon opening.
(32) "Secured
				valve" is a valve which is locked, plugged or capped.
(33) "Semi-trailer" refers to a vehicle
				designed for carrying anhydrous ammonia, which is drawn by a motor vehicle, and
				so constructed that some part of its weight and that of its load rests upon or
				is carried by another vehicle.

				"System" refers to an assembly of equipment consisting essentially of the
				container(s), appurtenances, pumps, compressors, and interconnecting
				piping.

				designed and constructed for the storage and handling of anhydrous
				ammonia.

				means any motor vehicle designed or used for the transportation of anhydrous
				ammonia in any tank designed to be permanently attached to any motor vehicle or
				any container not permanently attached to any motor vehicle which by reason of
				its size, construction or attachment to any motor vehicle must be loaded or
				unloaded without being removed from the motor vehicle.
