Current through Vol. 41, No. 20, July 1, 2024
(a)
General safety requirements.
(1)
				  Each tank used with a system shall be constructed and tested in accordance with
				  parts UG-1 through UG-36, inclusive, entitled "General Requirements for All
				  Methods of Construction and All materials" and parts UF-1 through UF-136
				  entitled "Requirements for Pressure Vessels Fabricated by Forging" as published
				  in Section VIII, Division I of the ASME Boiler and Pressure Vessel Code, July
				  1, 1983 edition amendments, supplements, or successors.
(2) No person shall fill a storage or nurse
				  tank with anhydrous ammonia unless the tank bears a manufacturer's nameplate
				  showing that it is a code container.
(3) The copy of the report form from each
				  inspection and re-qualification, together with tank repair and mill test
				  reports, if any, shall be maintained for the entire service life of the tank.
				  The reports shall be forwarded with the tank when relocated.
(4) For protection to the public and safety
				  for individuals, the storage of nurse tanks shall conform to the same
				  subsection as permanent storage installations in order to prevent tampering by
				  individuals, which may cause injury to human health.
(5) Anhydrous ammonia tanks of three thousand
				  (3,000) gallon water capacity or less shall not be used for any other commodity
				  except anhydrous ammonia.
(6) Tank
				  trucks, semi-trailers, nurse tanks, and trailers transporting anhydrous ammonia
				  shall not be left unattended on public thoroughfares or in densely populated
				  areas.
(7) If the ammonia hose is
				  marked with:
(A) the year of manufacture and
				  made from the following materials, it shall be replaced per the indicated
				  service life with not more than one (1) year shelf life added:
(i) Rayon - 2 years
(ii) Nylon - 4 years
(iii) Stainless Steel - 6 years
(B) a manufacturer's removal date,
				  it shall be replaced prior to that date (i.e., the manufacturer removal date is

(8) All anhydrous ammonia high pressure
				  transfer hoses shall be clearly marked at least once every five (5) feet with
				  the manufacturer's name or trademark, the words Anhydrous Ammonia, the maximum
				  working pressure in PSIG, and the year of manufacture or manufacture removal
				  date. Bulk hoses shall not be used. All hose ends shall be connected by the
				  manufacturer.
(9) Any accident or
				  release, involving anhydrous ammonia, shall be reported (telephone or fax) to

				  twenty-four (24) hours following the incident, so that an investigation may be
				  made before the area is disturbed.
(A) An
				  accident includes nurse tanks that have been in a wreck, overturned tanks,
				  vandalism (without a release), storage tank being damaged, or "ANY" personal
				  injuries.
(B) A release includes
				  valve malfunctions, ruptured hoses, or any time anhydrous ammonia is released
				  into the air with the exception of safety relief (pop off and hydrostatic)
				  valves.
(10) Converted
				  railroad tank cars shall not be used for the storage of anhydrous ammonia
				  unless they have been retested and meet the requirements of this
				  subsection.
(11) All storage
				  installations shall have on hand, as a minimum, the following equipment in a
				  readily accessible location for emergency and rescue purposes:
(A) One full face gas mask with one
				  industrial size ammonia canister with current date and at least one spare
				  ammonia canister in a readily accessible location. A positive pressure
				  self-contained breathing apparatus shall be used in ammonia contaminated
				  atmospheres that are immediately dangerous to life or health. Gas masks and
				  self-contained breathing apparatus shall be approved by NIOSH/MSHA under
				  provisions of 30 CFR Part II. Procedures and training shall be in accordance
				  with 29 CFT Part 1910 and documented.
(B) One pair of approved protective gloves
				  made of material impervious to anhydrous ammonia.
(C) One pair of protective boots made of
				  material impervious to anhydrous ammonia.
(D) One protective slicker and/or protective
				  pants and jacket made of material impervious to anhydrous ammonia.
(E) Approved flexible fitting, hooded
				  ventilation goggles and one full face shield.
(12) Each employee shall be provided with a
				  pair of approved gloves and a pair of approved flexible fitting, hooded
				  ventilation goggles and, as an option, a full face shield worn over the
				  goggles, which shall be worn when making, breaking, or testing, any ammonia
				  connection, transferring ammonia, or performing maintenance on an ammonia
				  system under pressure.
(13) Each
				  vehicle transporting anhydrous ammonia shall carry a container of at least five
				  gallons of water and shall be equipped with one pair approved protective
				  gloves; a full face gas mask; a pair of approved flexible fitting hooded
				  ventilation goggles, and as an option, one full face shield to be worn over the
				  goggles. The driver shall be instructed in their use and the proper action to
				  take to provide for their safety.
(14) If a leak occurs in transportation
				  equipment and it is not practical to stop the leak, the driver should move the

				  traveled highways.
(15) Wheel
				  chocks for nurse tanks and railcars shall be available and shall be used when
				  loading or unloading.
(16) It is a
				  violation for any person to transfer or deliver any anhydrous ammonia into a
				  storage or nurse tank having defects which are plainly apparent.
(17) No container pressure relief device
				  shall be used after the replacement date as specified by the
				  manufacturer.
(18) An attendant is
				  required to transfer anhydrous ammonia and shall be trained in safe operating
				  practices, use of equipment, safety devices, and the proper action to take in

				  Additional safety guidelines found in the American National Standards
				  Institute, Inc., Safety Requirements for Storage and Handling of Anhydrous
