1 ** This Table appears in Recommended Separation Distances of Ammonium Nitrate and Blasting Agents from Explosives or Blasting Agents, adopted as an NFPA Tentative Standard (No. 492-T) in 1967. For a discussion of the derivation of the Table and examples of how it is applied to actual storage situations, see No. 492-T. NFPA 495 46 NOTE A46 New reference replaced reference to tentative recommendations in Information Circular 7988. New is as follows: "Safety Recommendation for Sensitized Ammonium Nitrate Blasting Agents," Bureau of Mines, U.S. Department of Interior, Information Circular 8179, 1963. NOTES TO TABLE OF RECOMMENDED SEPARATION AMMONIUM NITRATE AND BLASTING AGENTS FROM EXPLOSIVES OR BLASTING AGENTS Note 1 — Recommended separation distances to prevent explosion of ammonium nitrate and ammonium nitrate based blasting agents by propagation from nearby stores of high explosive or blasting agents referred to in the Table as the "donor." Ammonium nitrate, by itself, is not considered to be a donor when applying this Table. If stores of ammonium nitrate are located within the sympathetic detonation distance of explosives or blasting agents, one-half the mass of the ammonium nitrate should be included in the mass of the donor. 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." These distances apply to the separation of stores only. The American Table of Distances shall be used in determining separation distances from inhabited buildings, passenger railways, and public highways. Note 2 — When the ammonium nitrate and/or blasting agent is not barricaded, the distances shown in the Table shall be multiplied by six. Where storage is in bullet-resistant magazines recommended for explosives, or where the storage is protected by a bullet resistant wall, distances and barricade thickness in excess of those prescribed in the American Table of Distances are not required. Note 3 — The distances in the Table apply to ammonium nitrate that passes the insensitivity test prescribed in the National Plant Food Institute;** and ammonium nitrate failing to pass said test shall be stored at separation distances determined by competent persons and approved by the State Fire Marshal’s Office. Note 4 — These distances apply to nitro-carbo-nitrates and blasting agents which pass the insensitivity test prescribed in the DOT regulations. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– * For construction of bullet-resistant magazines, see Chapter 3, NFPA 1967–68. ** Definition and Test Procedures of Ammonium Nitrate Fertilizer, National Plant Food Institute, November 1964. Note 5 — Earth or 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 surroundings exposures which require protection cannot be seen from the "donor" when the trees are bare of leaves, are also acceptable. Note 6 — When the ammonium nitrate must be counted in determining the distances to be maintained from inhabited buildings, passenger railways and public highways, it may be counted at one-half its actual weight. |
