Notes to Table of Recommended Separation
Distances of 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 explosives 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. 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 the mass of ammonium nitrate should be included in the mass of
					 the donor.
Note 2- When the ammonium nitrate and/or blasting agent is
					 not barricaded, the distances shown in the Table 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
					 magazines1 recommended for explosives or where the
					 storage is protected by a bullet-resistant wall, distances and barricade
					 thicknesses 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 definition of
					 ammonium nitrate fertilizer promulgated by the Fertilizer
					 Institute;2 and ammonium nitrate failing to pass
					 said test shall be stored at separation distances determined by competent
					 persons and approved by the authority having jurisdiction.
Note 4- These distances apply to blasting agents which pass
					 the insensitivity test prescribed in regulations of the U.S. Department of
					 Transportation and the U.S. Department of the Treasury, Bureau of Alcohol,
					 Tobacco and Firearms.
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 surrounding exposures which require protection cannot be seen from the
					 "donor" when the trees are bare of leaves, are also acceptable.
Note 6- For determining the distances to be maintained from
					 inhabited buildings, passenger railways, and public highways, use the American
					 Table of Distances for Storage of Explosives Materials.
