Ammonium nitrate, by itself, is not considered to be a donor when applying this Table. Ammonium nitrate, ammonium nitrate-fuel oil or binations 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. com 186.21 186.22 186.23 14 12 18 22 25 29 25 25 30 30 30 35 35 35 40 40 40 40 50 50 50 50 Subpart B-Definitions 186.11 Meaning of terms. Subpart C-Gauging Instruments General requirements. Hydrometers and thermometers. 186.24 Use of U.S. standard hydrometers and thermometers. 1 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 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 the American Table of Distances are not required. 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 National Piant Food Institute; 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. 3 These distances apply to nitro-carbo-nitrates and blasting agents which pass the insensitivity test prescribed in the U.S. Department of Transportation (DOT) regulations. 4 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.

Subpart A-Scope of Regulations § 186.1 Gauging of distilled spirits. This part, the "Gauging Manual", relates to the gauging of distilled spirits. By "gauging" is meant the determination of the proof and the quantity of distilled spirits. Tables 1-7, together with their instructions, are provided as a part hereof and should be used, wherever applicable, in making the necessary computations from gauge data. Table 1 provides a method for correcting hydrometer indications at temperatures between 0 and 100 degrees Fahrenheit to true proof. If distilled spirits contain dissolved solids, temperature-correction of the hydrometer reading by the use of this table would result in apparent proof rather than true proof. Tables 2 and 3 show the gallonage of spirituous liquor according to weight and proof, Table 4 shows the gallons per pound at each onetenth proof from 1 to 200 proof, Table 5 shows the weight per wine gallon and proof gallon at each proof, Table 6 shows the volumes of alcohol and water, and the specific gravity (air and vacuum) of spirituous liquor at each proof, and Table 7 provides a means of ascertaining the volume (at 60 degrees Fahrenheit) of spirits at various temperatures ranging from 18 degrees through 100 degrees Fahrenheit. The procedures prescribed in, or authorized under the provisions of, this part shall, except as may be otherwise authorized in this chapter, be followed in making any determination of quantity or proof of distilled spirits required by or under the authority of regulations in this chapter. (72 Stat. 1358; 26 U.S.C. 5204) Subpart B--Definitions § 186.11 Meaning of terms. When used in this part, where not otherwise distinctly expressed or manifestly incompatible with the intent thereof, terms shall have the meanings ascribed in this section. Words in the plural form shall include the singular, and vice versa, and words importing the masculine gender shall include the feminine. The terms "includes" and "including" do not exclude things not enumerated which are in the same general class. Assistant regional commissioner. An assistant regional commissioner (alcohol, tobacco and firearms) who is responsible to, and functions under the direction and supervision of, a regional commissioner. Bulk conveyance. Any tank car, tank truck, tank ship, tank barge, or other similar container approved by the Director, authorized for the conveyance of spirits (including denatured spirits) in bulk. |
