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, Firearms and Explosives of the U.S. Department of Justice.
				  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. However, 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 that 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 12/3 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 that require protection cannot be seen from the magazine
				  when the trees are bare of leaves.
NOTE 7 - "Artificial Barricade" means an
				  artificial mound or revetted wall of earth of a minimum thickness of 3 feet at
				  the top of the mound or wall, or a mound or revetted wall of other material
				  offering equivalent protection. Artificial barricades that are vegetated shall
				  be of sufficient slope to enable mowing.
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 the
				  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 that carries 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 those 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 those
				  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 to the transportation, handling or storage. 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, the
				  building shall be located away 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.
(NOTE: The American Table of Distances for Storage of
				  Explosive Materials and accompanying Explanatory Notes are copyrighted
				  materials reproduced with the permission of the Institute of Makers of
				  Explosives. The notes contained in this Appendix are meant to supplement, and
				  not supersede, the regulations contained in this Part. When wording differs
				  between the regulations and these explanatory notes, the regulations shall
				  govern for enforcement purposes.)
