				  not classified as an explosive and in which none of the ingredients is
				  classified as an explosive provided the furnished (mixed) product cannot be
				  detonated with a No. 8 test blasting cap when confined. A common blasting agent
				  presently in use is a mixture of ammonium nitrate (general) and carbonaceous

				  by means of a test blasting cap containing two (2) grams of a mixture eighty
				  percent (80%) mercury fulminate and twenty percent (20%) potassium chlorate, or
				  a cap of equivalent strength. Blasting agent shall not include explosives in

				  between electric blasting caps and the leading wires or between the bus wire
				  and the leading wires.
(C) Leading wire. An insulated wire used between the electric
				  power source and the electric blasting cap circuit.
(D) Permanent blasting wire. A permanently mounted insulated
				  wire used between the electric power source and the electric blasting cap
				  circuit.
"Electric delay blasting caps"
means caps
				  designed to detonate at a predetermined period of time after energy is applied
				  to the ignition system.
"Explosive"
means as follows:
(A) Any chemical compound, mixture, or device, the primary or
				  common purpose of which is to function by explosion; that is, with
				  substantially instantaneous release of gas and heat, unless such compound,
				  mixture or devise is otherwise specifically classified by the U.S. Department
				  of Transportation.
(B) All material which is classified as Class I. Class I is
				  as follows:

				  boosters, cap sensitive emulsions, water gels and slurries, Class A
				  detonators).
(ii) Division 1.2 - Class A or Class B explosives (Division

				  percussion, by chemical reaction, or by detonation of any part of the compound
				  or mixture may cause gaseous pressures capable of producing destructive effects
				  on contiguous objects or of destroying life or limb Provided, that dynamite,
				  nitroglycerin, gunpowder, blasting powder and trinitrotoluene shall be deemed
				  explosives without further proof of their nature. It shall also include all
				  material which is classified as explosive by the United States Department of

				  handling, including mudcapping and blockholing.
"Semiconductive hose"
