Current through Register Vol. 50, No. 6, June 20, 2024
A. All
				  explosives, including black powder in excess of 5 pounds, except when preempted
				  by federal or state regulations, shall be kept in magazines which meet the
				  requirements of these rules and regulations. Blasting agents shall be stored in
				  accordance with the requirements set forth in §1515 Storage of explosives
				  in underground mining operations is exempt from the rules and regulations set
				  forth in this Section, but must comply with all applicable federal regulations
				  set forth in  30 CFR Part 57 . Underground mine storage will provide all adequate
				  safety and security procedures necessary to ensure that unlicensed personnel
				  will not have access to the explosives. Such security must be approved by the
				  Deputy Secretary of Public Safety Services.
B. Loaded perforating guns are not required
				  to be stored in magazines. Storage of these explosive devices must be in a
				  secured area approved by the Deputy Secretary of Public Safety
				  Services.
C. Detonators shall not
				  be stored in the same magazines with other explosives.
D. The ground around outdoor magazines shall
				  slope away for drainage. The land surrounding outdoor magazines shall be kept
				  clear of brush, dried grass, leaves, and other combustible materials for a
				  distance of 50 feet in each direction.
E. Magazines, as required by these rules and
				  regulations, shall be used for the storage of explosives only, and shall be of
				  five Types, 1 through 5.
F. When a
				  building or magazine containing ammonium nitrate and/or blasting agents is not
				  barricaded, the distances shown in Table 2 shall be doubled.
G. Magazines must be located on property in
				  accordance with the American Table of Distances for Storage of Explosives
				  (§1545, Table 1).
H. When two
				  or more storage magazines are located on the same property, each magazine must
				  comply with the minimum distances specified from inhabited buildings, railways
				  and highways; and in addition, they shall be separated from each other by not
				  less than the distances shown for Separation of Magazines, (Table 1) except
				  that the quantity of explosives contained in detonator magazines shall govern
				  in regard to the spacing of said detonator magazines from magazines containing
				  other explosives. If any two or more magazines are separated from each other by
				  less than the specified Separation of Magazines (Table 1) distances, then such
				  two or more magazines, as a group, must be considered as one magazine, and the
				  total quantity of explosives stored in such group must be treated as if stored
				  in a single magazine located on the site of any magazine of the group, and must
				  comply with the minimum of distances specified from other magazines, inhabited
				  buildings, railways and highways.
1. All types
				  of detonators in strengths up to and including No. 8 detonators shall be rated
				  at 1.5 pounds of explosives per 1,000 caps. Detonating cord, 50 grains, shall
				  be rated at 8 pounds of explosives per 1,000 feet. Detonating cords with larger
				  or smaller grains per foot will be rated proportionately.
2. Explosive operations carried out on a
				  vessel shall be required to comply with the distances shown for Separation of
				  Magazines (Table 1) only as the physical limitations of the vessel will permit.
				  Explosive magazines shall not be located under, over, or immediately adjacent
				  to pressurized gas lines or high voltage power lines, or on levees constructed
				  for major flood control.
