(2) "Blast area" means the area in which
			 explosives loading and blasting operations are being conducted.
(3) "Blaster" means the person having a
			 comprehensive knowledge of the installation and use of appliances associated
			 with the type of blasting operations being performed, designated by the
			 employer to perform and direct the functions of placing and fixing explosives,
			 firing, approaching misfires, thawing explosives and all other duties in
			 connection with the blasting operation.
(4) "Blasting agent" means any material or
			 mixture consisting ofa fuel and oxidizer used for blasting, but not classified
			 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.
(5) "Blasting
			 cap" means a metallic tube closed at one end, containing a charge of one or
			 more detonating compounds, and designed for and capable of detonation from the
			 sparks or flame from a safety fuse inserted and crimped into the open end.
(6) "Bus wire" means an insulated
			 expendable wire used between connecting wires and leading wires.
(7) "Connecting wire" means an insulated
			 expendable wire used between electric blasting caps and the bus wires or
			 leading wires.
(8) "Detonating
			 cord" means a flexible cord containing a center core of high explosives which
			 when detonated, will have sufficient strength to detonate other cap-sensitive
			 explosives with which it is in contact.
(9) "Detonator" means igniters, blasting
			 caps, electric blasting caps, or similar devices used to explode explosives.
(10) "Explosive" means any
			 chemical compound or mixture that is intended for the purpose of producing an

			 ingredients in such proportions, quantities, or packing that an ignition by
			 fire, by friction, by concussion, by percussion, or by a detonator, of any part
