Section R11-1-221. Definitions -- explosives

A.       “Blasting agent”: Shall mean any material or mixture consist- ing of a fuel and oxidizer, intended for blasting, not otherwise classified as an explosive, and of which none of the ingredi- ents are classified as an explosive, provided that the finished product, as mixed and packaged for use or shipment, cannot be detonated when unconfined by means of a No. 8 test blasting cap. This test should be conducted at a temperature range between 70° and 75° F.

Note 1. A No. 8 test blasting cap is one containing two grams of a mixture of 80% mercury fulminate and 20% potassium chlorate, or a cap of equivalent strength.

Note 2. Nitro carbo nitrate. This term applies to any blasting agent which has been classified as nitro carbo nitrate under the Department of Transportation regulations, and which is pack- aged and shipped in compliance with the regulations of the Department of Transportation.

B.       “Explosives”: The term “explosive” or “explosives” shall mean any chemical compound, mixture or device, the primary or common purpose of which is to function by explosion, i.e., with substantially instantaneous release of gas and heat, unless such compound, mixture or device is otherwise specifically

classified by the Department of Transportation. The term “explosives” shall include all material which is classified as Class A, Class B, and Class C explosives by the Department of Transportation.

Note 1. Classification of explosives by the United States Department of Transportation is as follows:

1.        “Class A explosives”: Possessing detonating hazards; such as dynamite, nitroglycerin, TNT, black powder blasting caps and cast detonating primers and boosters.

2.        “Class B explosives”: Possessing flammable hazard; such as propellant explosives, including some smokeless pro- pellants.

3.        “Class C explosives”: Includes certain types of manufac- tured articles which contain Class A or Class B explo- sives, or both, as components but in restricted quantities.

4.        “Fuel”: A fuel is a substance which may react with the oxygen in the air or with the oxygen yield by an oxidizer to produce combustion.

5.        “Magazine”: Shall mean any building or structure, other than an explosives manufacturing building, approved for the storage of explosives.

6.        “Oxidizer”: An oxidizer is a substance such as a nitrate that yields oxygen readily to stimulate the combustion of organic matter or other fuel.
