Explanatory Notes Essential to the Application of the
					 American Table of Distances for Storage of Explosive Materials
Note 1-
Explosive Materials
means
					 explosives, blasting agents and detonators.
Note 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
					 should be calculated as equivalent to 8 lbs. of high explosives per 1,000 feet.
					 Heavier or lighter core loads should be rated proportionately.
Note 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.
Note 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 with safety fuses, detonating cord delay connectors, and
					 nonelectric 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 lbs. of
					 explosives per 1,000 caps. For strengths higher than No. 8 cap, consult the
					 manufacturer.
Note 5-
Magazine
means any building,
					 structure, or container, other than an explosives manufacturing building,
					 approved for the storage of explosive materials.
Note 6-
Natural Barricade
means natural
					 features of the ground, such as hills, or timber of sufficient density that the
					 surrounding exposures which require protection cannot be seen from the magazine
					 when the trees are bare of leaves.
Note 7-
Artificial Barricade
means an
					 artificial mound or riveted wall of earth of a minimum thickness of 3
					 feet.
Note 8-
Barricaded
means the effective
					 screening of a building containing explosive materials from the magazine or
					 other building, 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 above the center of a railway or highway shall pass through such
					 barrier.
Note 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.
Note 10-
Railway
means any steam,
					 electric, or other railroad or railway which carriers passengers for
					 hire.
Note 11-
Highway
means any public street,
					 public alley, or public road.
Note 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.
Note 13- Storage in excess of 300,000 lbs. of explosive
					 materials, in one magazine is generally not required for commercial
					 enterprises.
Note 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
					 incident thereto. It is not intended to apply to bombs, projectiles, or other
					 heavily encased explosives.
Note 15- When a manufacturing building on an explosive
					 materials plant site is designed to contain explosive materials, such building
					 shall be located from inhabited buildings, public highways and passenger
					 railways in accordance with the American Table of Distances based on the
					 maximum quantity of explosive materials permitted to be in the building at one
					 time.
American Table of Distances
The American Table of Distances applied to the manufacture
					 and permanent storage of commercial explosive materials. The distances
					 specified are those measured from the explosive materials storage facility to
					 the inhabited building, highway or passenger railway, irrespective of property
					 lines.
The American Table of Distances covers all commercial
					 explosive materials, including, but not limited to, high explosives, blasting
					 agents, detonators, initiating systems and explosives materials in process. The
					 Table is not designed to be altered or adjusted to accommodate varying
					 explosive characteristics such as blast effect, weight strength, density, bulk
					 strength, detonation velocity, etc.
The American Table of Distances should not be used to
					 determine safe distances for blasting work, the firing of explosive charges for
					 testing or quality control work, or the open detonation of waste explosive
					 materials. The American Table of Distances may be utilized as a guide for
					 developing distances for the unconfined, open burning of waste explosive
					 materials where the probability of transition from burning to high order
					 detonation is improbably.
