15-20-010 Definitions.
"Explosives" means any chemical compounded or mechanical mixture which is commonly used or intended for the purpose of producing an explosion, or which contains any oxidizing and combustible units, or other ingredients, in such proportions, quantities or packing that an ignition by fire, by friction, by concussion, by percussion, or by detonator of any part of the compound or mixture may cause such a sudden generation of highly heated gases that the resultant gaseous pressures will be capable of producing destructive effects on contiguous objects or of destroying life or limb articles subdivided as follows:
(a) Unlawful Explosives. The manufacture, storage, sale, transportation or use of the following explosives is hereby prohibited:
1. Liquid nitroglycerine, except for medicinal purposes;

3. Nitroglycerine dynamite containing over 60 percent of nitroglycerine, or gelatine dynamite equal in strength to over 75 percent of nitroglycerine dynamite;
4. Blasting caps containing less than nine and one-half grains of explosive mixture, at least 80 percent fulminate of mercury and 20 percent chlorate of potash, or its equivalent detonating strength;
5. Any fulminate of mercury in a dry condition;
6. Any fulminate of other metals in any condition except as a component of articles not otherwise prohibited;
7. Any fireworks which combine an explosive and a detonator;
8. Nitrocellulose in a dry and uncompressed condition in quantity greater than ten pounds net weight in one package;
9. Explosive compositions that ignite spontaneously or undergo marked decomposition, rendering the products or their use more hazardous, when subjected to 48 consecutive hours or less to a temperature of 167 degrees Fahrenheit;
10. New explosives until approved by the United States Department of Transportation, except that permits may be issued to educational, governmental or industrial laboratories for instructional or research purposes;
11. Explosives condemned by the United States Department of Transportation;
12. Explosives not packed or marked in accordance with the requirement of the United States Department of Transportation;
