Current through Register Vol. 51, No. 1, July 1, 2024
RELATES TO: KRS 351.315, 351.330, 351.335, 351.350
NECESSITY, FUNCTION, AND CONFORMITY: KRS 351.335 requires the
				Department for Natural Resources to promulgate rules and administrative
				regulations concerning the manufacture, transportation, sale, storage, or use
				of explosives, and the maintenance of such explosives which has a direct
				bearing on safety to life and property. This administrative regulation provides
				the definitions applicable to the provisions of that law.
Section 1.
(1) "Artificial barricade" means an
			 artificial mound or revetted wall of earth of a minimum thickness of three (3)
			 feet, or any other approved barricade that offers equivalent
			 protection.
(2) "Barricaded" means
			 the effective screening of a magazine containing explosive materials from
			 another magazine, a building, a railway, or a highway, either by a natural or
			 artificial barricade. To be properly barricaded, a straight line from the top
			 of any sidewall of the magazine to the eave line of any other magazine or
			 building, or to a point twelve (12) feet above the center of a railway or
			 highway will pass through the barricade.
(3) "Blast area" means the area in which
			 explosives loading and blasting operations are being conducted.
(4) "Blasting agent" means any material or
			 mixture consisting of a 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 when confined.
(5)
			 "Blasting cap" means a metallic tube closed at one end, containing a charge of
			 one or more detonating compounds, and designed for detonation from the sparks
			 or flame from a safety fuse inserted and crimped into the open end.
(6) "Block holing" means the breaking of
			 boulders by firing a charge of explosives that has been loaded in a drill
			 hole.
(7) "Conveyance" means any
			 unit for transporting explosives or blasting agents, including but not limited
			 to trucks, trailers, rail cars, barges, and vessels.
(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
			 blasting caps, electric blasting caps, delay electric blasting caps, and
			 nonelectric delay blasting caps.
(10) "Electric cap" means a blasting cap
			 designed for and capable of detonation by means of an electric blasting
			 current.
(11) "Electric delay
			 blasting caps" means caps designed to detonate at a predetermined period of
			 time after energy is applied to the ignition system.
(12) "Flyrock" means any dirt, mud, stone,
			 fragmented rock or other material that is displaced from the blast site by
			 being thrown in the air or cast along the ground.
(13) "High explosives" means any material
			 that will detonate when initiated by a blasting cap and where the chemical
			 reaction proceeds at supersonic velocities and produces high temperature, high
			 pressure gases and an associated shock wave.
(14) "Fuse lighters" means special devices
			 for the purpose of igniting a safety fuse.
(15) "Low explosives" are materials which
			 deflagrate producing high temperature, high pressure gases. They may be
			 initiated with a blasting cap, or by flame, heat or impact, however, they do
			 not present a mass detonation hazard.
(16) "Magazine" means any building or
			 structure, other than an explosives manufacturing building, used for the
			 storage of explosives.
(17)
			 "Misfire" means an explosive charge which failed to detonate.
(18) "Mud capping" (also known as bulldozing,
			 adobe blasting, or dobying) means a method of blasting by placing a quantity of
			 explosives in contact with a rock, boulder, or other object without confining
			 the explosives in a drill hole.
(19) "Natural barricade" means hills or
			 timber of sufficient density that the surrounding exposures which require
			 protection cannot be seen from the magazine when the trees are bare of
			 leaves.
(20) "Nonelectric delay
			 blasting cap" means a blasting cap with an integral delay element in
			 conjunction with and capable of being detonated by a detonation impulse or
			 signal for miniaturized detonating cord.
(21) "Primer" means a cartridge or container
			 of explosives into which a detonator or detonating cord is inserted or
			 attached.
(22) "Safety fuse" means
			 a flexible cord containing an internal burning medium by which fire is conveyed
			 at a continuous and uniform rate for the purpose of firing blasting
			 caps.
(23) "Stemming" means a
			 suitable inert incombustible material or device used to confine or separate
			 explosives in a drill hole, or to cover explosives in mud capping.
(24) "Springing" means the creation of a
			 pocket in the bottom of a drill hole by the use of a moderate quantity of
			 explosives in order that larger quantities of explosives may be inserted
			 therein.
