RECOMMENDED SEPARATION DISTANCES FOR EXPLOSIVE MATERIALS (See Chapter 33)
The following information is provided as reference information for application of Chapter 56 and IC 22-11-14.
The information provided in Section 1 is excerpted from federal regulations in 49 CFR, Parts 171-173. A discussion of the new regulations is also provided.
Table A-VI-F-5 is reprinted with permission of the Institute of Makers of Explosives with the provision that the entire table, complete with all explanatory footnotes, is printed. Table A-VI-F-5 is used for magazines containing high explosives or a combination of high explosives and low explosives, and for magazines containing blasting agents.
TABLE A-VI-F-2 - DEFINITIONS FOR DIVISIONS OF CLASS 1 (EXPLOSIVE) MATERIALS DIVISION DEFINITION
TABLE A-VI-F-2 - DEFINITIONS FOR DIVISIONS OF CLASS 1 (EXPLOSIVE) MATERIALS | |
DIVISION | DEFINITION |
1.1 | Explosives that have a mass hazard explosion. A mass explosion is one that affects almost the entire load instantaneously. (Examples include dynamite, cap-sensitive water gels, slurries, emulsions, and cast boosters.) |
1.2 | Explosives that have a projection hazard but not a mass explosion hazard. (Examples include ammunition, projectiles, and bombs.) |
1.3 | Explosives that have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard. (Examples include some propellants, some fireworks, and flares.) |
1.4 | Explosive devices that present a minor explosion hazard. External fire must not cause virtually instantaneous explosion of almost the entire contents of the package. (Examples include some detonators and detonating cords, safety fuse, electric squibs, igniters, igniting cord, and some fireworks.) |
1.5 | Very insensitive explosives. This division is comprised of substances that have a mass explosion hazard but are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions of transport. (Examples include blasting agents.) |
1.6 | Extremely incentive articles that do not have a mass explosion hazard. This division is comprised of articles that contain only extremely insensitive detonation substances and that demonstrate a negligible probability of accidental initiation or propagation. (This division is not commonly used for commercial explosives.) |

1 "Explosive materials" means explosives, blasting agents and detonators.
2 "Explosives" means any chemical compound, mixture, or device, the primary or common purpose of which is to function by explosion. A list of explosives determined to be within the coverage of 18 U.S.C. Chapter 40, Importation, Manufacturer, Distribution and Storage of Explosive Materials, is issued at least annually by the director of the Bureau of Alcohol, Tobacco and Firearms of the Department of the Treasury. For quantity and distance purposes, detonating cord of 50 grains per foot (10.7g/m) should be calculated as equivalent to 8 pounds (3.6 kg) of high explosives per 1,000 feet (304.8 m). Heavier or lighter core loads should be rated proportionately.
3 "Blasting agents" means any material or mixture, consisting of fuel and oxidizer, intended for blasting, not otherwise defined as an explosive, provided that the finished product, as mixed for use or shipment, cannot be detonated by means of a No. 8 test blasting cap when unconfined.
4 "Detonator" means any device containing any initiating or primary explosive that is used for initiating detonation. A detonator may not contain more than 10 grams of total explosives by weight, excluding ignition or delay charges. The term includes, but is not limited to, electric blasting caps of instantaneous and delay types, blasting caps for use within safety fuses, detonating cord delay connectors, and non-electric instantaneous and delay blasting caps which use detonating cord, shock tube or any other replacement for electric leg wires. All types of detonators in strengths through No. 8 cap should be rated at 1 1/2 pounds (0.68 kg) of explosives per 1,000 caps. For strengths higher than No. 8 cap, consult the manufacturer.
5 "Magazine" means any building, structure, or container, other than an explosives manufacturing building, approved for the storage of explosive materials.
6 "Natural barricade" means natural features of the ground such as hills, or timber of sufficient density that the surrounding exposure which require protection cannot be seen from the magazine when the trees are bare of leaves.
7 "Artificial barricade" means an artificial mound or riveted wall of earth of a minimum thickness of 3 feet (914.4 mm).
8 "Barricaded" means the effective screening of a building containing explosive materials from the magazine or other building, railway or highway by a natural
9 "Inhabited building" means a building regularly occupied in whole or part as a habitation for human beings, or any church, schoolhouse, railroad station, store, or other structure where people are accustomed to assemble, except any building or structure occupied in connection with the manufacture, transportation, storage, or use of explosive materials.
10 "Railway" means any steam, electric, or other railroad or railway that carries passengers for hire.
11 "Highway" means any public street, public alley, or public road.
12 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 should be separated from each other by not less than the distances shown for "Separation of Magazines", except that the quantity of explosive materials contained in detonator magazines shall govern in regard to the spacing of said detonator magazines from magazines containing other explosive materials. If any two or more magazines are separated from each other by less than the specified "Separation of Magazines" distances, then such two or more magazines, as a group, must be considered as one magazine, and the total quantity of explosive materials 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.
13 Storage in excess of 300,000 pounds (136,077.6 kg) of explosive materials in one magazine is generally not required for commercial enterprises.
14 This table applies only to the manufacture and permanent storage of commercial explosive materials. It is not applicable to transportation of explosives or any handling or temporary storage necessary or incidental thereto.

1 Recommended separation distances to prevent explosion of ammonium nitrate and ammonium nitrate-based agents by propagation from nearby stores of high explosives or blasting agents referred to in Table A-VI-F-6 as the "donor." Ammonium nitrate, by itself, is not considered to be a donor when applying Table A-1 Recommended separation distances to prevent explosion of ammonium nitrate and ammonium nitrate-based agents by propagation from nearby stores of high explosives or blasting agents referred to in Table A-VI-F-6 as the "donor." Ammonium nitrate, by itself, is not considered to be a donor when applying Table A-VI-F-6, Ammonium nitrate, ammonium nitrate-fuel oil, or combination 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 the ammonium nitrate should be included in the mass of the donor.
2 When the ammonium nitrate or blasting agent is not barricaded, the distances shown in Table A-VI-F-6 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 that 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 and barricade thicknesses in excess of those prescribed in Table A-VI-F-5, Footnote 7, are not required. For construction of bullet resistant magazines, see Article 77.
3 The distances in Table A-VI-F-6 apply to ammonium nitrate that passes the insensitivity test prescribed in the definition of ammonium nitrate fertilizer promulgated by the Fertilizer Institute (Definitions and Test Procedure for Ammonium Nitrate Fertilizer, Fertilizer Institute 1964); 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.
4 These distances apply to blasting agents which pass the insensitivity test prescribed in regulations of the United States Department of Transportation and the United States Department of the Treasury, Bureau of Alcohol, Tobacco and Firearms.
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 exposure which requires protection cannot be seen from the "donor" when the trees are bare of leaves, are also acceptable.
6 For determining the distances to be maintained from inhabited buildings, passenger railways, and public highways, see Table A-VI-F-5 (High Explosives and Blasting Agents) or Table A-VI-F-7 (Low Explosives).

1 This table is intended only for application of open burning of commercial explosive materials. The distances stated in this table should be measured from the center of the unit, except for separations from other open-burning units, which are measured from the edge of the unit.
2 "Explosive materials" means any explosive, slurry, emulsion, detonating cord, blasting agents, and detonators.
3 "Explosives" means any chemical compound, mixture, or device, the primary or common purpose of which is to function by explosion. A list of explosives determined to be within the coverage of 18 U.S.C. Chapter 40, Importation, Manufacture, Distribution and Storage of Explosive Material, is issued at least annually by the director of the Bureau of Alcohol, Tobacco, and Firearms of the Department of the Treasury. For quantity and distance purposes, detonating cord of 50 grains per foot (10.7 g/m) should be calculated as equivalent to 8 pounds (3.6 kg) of high explosives per 1,000 feet (304.8 m). Heavier or lighter core loads should be rated proportionally.
4 "Blasting agents" means any material or mixture, consisting of fuel and oxidizer, intended for blasting, not otherwise defined as an explosive, provided the finished product, as mixed for use or shipment, cannot be detonated by means of a No. 8 test blasting cap when unconfined.
5 "Detonator" means any device containing any initiating or primary explosive that is used for initiating detonation. A detonator may not contain more than 10 grams of total explosives by weight, excluding ignition or delay charges. The term includes, but is not limited to, electric blasting caps of instantaneous and delay blasting caps that use detonating cord, shock tube, or any other replacement for electric wires. All types of detonators in strengths through No. 8 cap should be rated at 1 1/2 pounds (0.68 kg) of explosives per 1,000 caps. For strengths higher than No. 8 cap, consult the manufacturer.
6 "Natural barricade" means natural features of the ground, such as hills, or timber of sufficient density that the surrounding exposures that require protection cannot be seen from the magazine when the trees are bare of leaves.
7 "Artificial barricade" means an artificial mound or riveted wall of earth of a minimum thickness of 3 feet (914.4 mm).
8 "Barricaded" means the effective screening of a building containing explosive materials from the magazine or other building, OB/OD site, railway, or highway by a natural or an artificial barrier. A straight line from the top of any sidewall of the building containing explosive materials to the eave line of any magazine or other building or to a point 12 feet (3,657.6 mm) above the center of a railway or highway shall pass through such a barrier.
9 "Inhabited building" means a building, regularly occupied in whole or part as a habitation for human beings, or any church, schoolhouse, railroad station, store, or other structure where people are accustomed to assemble. This does not mean any office, warehouse, production, laboratory, or other buildings that are a part of the facility where the open burning or open detonation sites are located.
10 "Highway" means any public street, public alley, or public road.
11 "Railway" means any steam, electric, or other railroad or railway that carries passengers for hire.
