Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						Bulk storage may be in piles or bins in warehouses, or in separate, bin-type
						structures.
(b) Unless constructed
						of noncombustible material or unless adequate facilities for fighting a roof
						fire are available, bulk storage structures shall not exceed a height of 40
						feet.
(c) Bins shall be free of
						materials which may contaminate ammonium nitrate.
(d) Due to the corrosive and reactive
						properties of ammonium nitrate, and to avoid contamination, galvanized iron,
						copper, lead and zinc shall not be used in bin construction unless suitably
						protected. Aluminum bins, and wooden bins protected against impregnation by
						ammonium nitrate, are permissible.
NOTE: Steel or wood can be protected by special
						  coatings such as sodium silicate (water glass), or epoxy coatings, or polyvinyl
						  chloride coatings.
(e) The
						warehouse may be subdivided into any desired number of ammonium nitrate storage
						compartments or bins. The partitions dividing the ammonium nitrate storage from
						the storage of other products which would contaminate the ammonium nitrate
						shall be of tight construction to eliminate cracks or crevices.
(f) The ammonium nitrate storage bins or
						piles shall be clearly identified by signs reading: "AMMONIUM NITRATE" with
						letters at least 2 inches high.
(g)
						Piles or bins shall be so sized and arranged that all material in the pile is
						moved out periodically in order to minimize possible caking of the stored
						ammonium nitrate.
(h) Height or
						depth of piles shall be limited by the pressure-setting (caking) tendency of
						the product. However, in no case shall the ammonium nitrate be piled higher at
						any point than 36 inches below the roof or supporting and spreader beams
						overhead.
NOTE: Pressure-setting (caking) is a factor affected by
						  humidity and temperature in the storage space and by pellet quality.
						  Temperature cycles through 90° F. and high atmospheric humidity are
						  undesirable for storage in depth.
(i) Ammonium nitrate shall not be accepted
						for storage when the temperature of the product exceeds 130° F.
EXCEPTION: Manufacturing or
						  processing.
(j) Explosive
						materials shall not be used to break up or loosen the caked, bagged, or bulk
						ammonium nitrate.

(d) Before repair work involving the use of
						open flames or other source of ignition, carboys or drums shall be purged of
						flammable vapors and insofar as is practicable, cleansed of residues which may
						give rise to such vapors. Ventilation, water, inert gas, or other suitable and
						effective means shall be used to prevent formation of explosive mixtures as
						necessary. Where such work is regularly or frequently undertaken, means shall
						be provided for testing the air in carboys or drums for
						explosibility.
(e) When carboys or

						operations are performed on tanks, vats, or containers, which contain or have
						last contained a flammable liquid or a substance giving rise to flammable
						vapors the following procedure shall be followed:
(1) Lines which may convey hazardous
						materials to the vessels shall be disconnected, or other positive means shall
						be used to prevent discharge of such material into the vessel.
(2) If work involving the use of flame, arc,
						spark, or other source of ignition is to be done, the vessel shall be emptied,
						flushed or otherwise purged of flammable vapors. A test for flammability of the
						vapors in the vessel shall be made, using an appropriate device for this
						purpose, and no source of ignition shall be permitted in or in contact with the
						vessel if the percentage of combustible vapor is greater than 25 percent of the
						lower explosive limit. As long as any source of ignition is used in or in
						contact with the vessel, frequent tests shall be made to determine the
						concentration of combustible vapors. If this concentration exceeds 25 percent
						of the lower explosive limit of the vapor present, sources of ignition shall be
						extinguished or removed until such concentration is reduced below 25 percent of
						the lower explosive limit.
NOTE: For suggested procedures, see NFPA
						  327-1982.
(3) Fire
						extinguishing equipment adequate to cope with the hazards which may be
						encountered shall be provided and maintained close at hand.
NOTE: See Article 108 for further instruction when
						  working in confined spaces.
