New York Codes, Rules and Regulations › Title 12 - DEPARTMENT OF LABOR › Chapter I - Industrial Board Of Appeals › Subchapter A - The Industrial Code › Part 39 - Possession, Handling, Storage And Transportation Of Explosives › Section 39.10 - General provisions for the possession, handling, storage and transportation of blasting agents

Current through Register Vol. 46, No. 28, July 10, 2024
All of the provisions of this Part (rule) relating to the
					 possession, handling, storage and transportation of explosives shall also apply
					 to blasting agents with the following exceptions:
(a) Separation distances of blasting agents
				  and ammonium nitrate from explosives or other blasting agents are given in
				  Table 3 of this Part (rule). Table 3 applies only to the separation of stores.
				  Table 1 shall be used in determining separation distances from inhabited
				  buildings, public highways and passenger railways. Separation distances to
				  prevent the explosion of ammonium nitrate and ammonium nitrate-based blasting
				  agents are referred to in Table 3 of this Part (rule) as the donor. Ammonium
				  nitrate, by itself, is not considered to be a donor when applying this table.
				  Ammonium nitrate, ammonium nitrate fuel oil, or combinations thereof, are
				  acceptors. If stores of ammonium nitrate are located within the sympathetic
				  detonation distance of explosives or blasting agents, one half of the mass of
				  the ammonium nitrate shall be included in the mass of the donor.
(b) When the ammonium nitrate and/or blasting
				  agents are not barricaded, the distances shown in Table 3 of this Part (rule)
				  shall be multiplied by six. Such distances allow for the possibility of
				  high-velocity metal fragments from mixers, hoppers, truck bodies, sheet metal
				  structures, metal containers and similar materials which may enclose the donor.
				  Where storage is in bullet-resistant magazines recommended for explosives or
				  where the storage is protected by a bullet-resistant wall, distances in excess
				  of those listed in Table 1 of this Part (rule) are not required.
(c) The distances in Table 3 of this Part
				  (rule) apply to ammonium nitrate that passes the insensitivity test prescribed
				  in the definition of ammonium nitrate fertilizer promulgated by the National
				  Plant Food Institute. Ammonium nitrate which fails to pass such insensitivity
				  test shall be stored at separation distances determined by the licensee and
				  such distances shall be acceptable to the commissioner.
(d) The separation distances listed in Table
				  3 of this Part (rule) also apply to nitro-carbo-nitrates and blasting agents
				  which pass the insensitivity test prescribed in the United States Department of
				  Transportation (DOT) regulations.
(e) Earth, sand dikes or enclosures filled
				  with the prescribed minimum thickness of earth or sand are acceptable
				  artificial barricades. Natural barricades, such as hills or timber of
				  sufficient density that the surrounding exposures which require protection
				  cannot be seen from the "donor" when the trees are bare of leaves, are also
				  acceptable.
(f) When the ammonium
				  nitrate must be counted in order to determine the separation distances from
				  inhabited buildings, public highways and passenger railways, it may be counted
				  at one half of its actual weight.
(g) Pneumatic loading equipment when handling
				  sensitized ammonium nitrate blasting agents shall not be grounded to water
				  lines, air lines, rails or permanent electrical grounding systems.
