Section 12:190-5.16 - Location of ammonium nitrate and blasting agents from high explosives or blasting agents

(a) Ammonium nitrate and ammonium nitrate-based blasting agents shall be separated from nearby stores of high explosives or blasting agents referred to as the "donor" by distances as provided in Table 5.16.

(b) If storage of ammonium nitrate is located within the sympathetic detonation distance of explosives or blasting agents, one-half the mass of the ammonium nitrate shall be included in the mass of the donor when calculating separation distances.

(c) When ammonium nitrate or a blasting agent or both is not barricaded, the distances shown in Table 5.16 shall be multiplied by six. These distances allow for the possibility of high velocity metal fragments from mixers, hoppers, truck bodies, sheet metal structures, metal containers, and the like 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, the distances and barricade thicknesses need not exceed those prescribed in Table 5.10.

(d) Table 5.16 shall apply to the blasting agents which pass the insensitivity test in the definition of blasting agent of N.J.A.C. 12:190-2.1.

(e) Earthen dikes, sand dikes, or enclosures filled with the required minimum thickness of earth or sand shall be acceptable artificial barricades. Hills or timber of sufficient density shall be acceptable natural barricades.

(f) For determining the distances to be kept from inhabited buildings, passenger railways, and public highways, Table 5.10 shall apply. Ammonium nitrate, when stored with blasting agents or explosives, may be counted at one half its actual weight.
