Missouri Code of State Regulations › Title 11 - DEPARTMENT OF PUBLIC SAFETY › Division 40 - Division of Fire Safety › Chapter 7 - Blasting › Section 11 CSR 40-7.010 - Blasting-Licensing, Registration, Notification, Requirements, and Penalties

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This amended rule incorporates changes to
				  the explosives used annual fee structure based upon the passage of SCS HCS HB
				  1286 (2018) and clarifies location data to be collected for the blast sites and
				  seismograph monitoring devices.
(1) The following definitions shall be used
				in interpreting this rule:
(A) "Blaster," a
				person qualified to be in charge of and responsible for the loading and firing
				of an explosive or explosive material;
(B) "Blast," detonation of
				explosives;
(C) "Blasting," the use
				of explosives in mining or construction;
(D) "Blast site," the area where explosives
				are handled during loading of a bore hole, including fifty feet (50') in all
				directions from the perimeter formed by loaded holes. A minimum of thirty feet
				(30') may replace the fifty- (50-) foot requirement if the perimeter of loaded
				holes is marked and separated from non-blast site areas by a barrier. The
				fifty- (50-) foot or thirty- (30-) foot distance requirements, as applicable,
				shall apply in all directions along the full depth of the bore hole;
(E) "Board," the State Blasting Safety Board
				created in section
				319.324,
				RSMo;
(F) "Bore hole," a hole made
				with a drill, auger, or other tool in which explosives are placed in
				preparation for detonation;
(G)
				"Burden," the distance from an explosive charge to the nearest free or open
				face at the time of detonation;
(H)
				"Business day," any day of the week except Saturday, Sunday, or a federal or
				state holiday;
(I) "Deck," charge
				of explosives separated from other charges by stemming;
(J) "Delay period," the time delay provided
				by blasting caps which permits firing of bore holes in sequence;
(K) "Detonation," the action of converting
				the chemicals in an explosive charge to gases at a high pressure by means of a
				self-propagating shock wave passing through the charge;
(L) "Detonator," any device containing
				initiating or primary explosive that is used for initiating detonation of
				another explosive material. A detonator may not contain more than ten (10)
				grams of total explosives by weight, excluding ignition or delay charges. The
				term includes, but is not limited to, electric blasting caps of instantaneous
				and delay types, blasting caps for use with safety fuse, detonating cord delay
				connectors, and nonelectric instantaneous and delay blasting caps which use
				detonating cord, nonelectric shock tube, or any other replacement for electric
				leg wires;
(M) "Division," the
				Missouri Division of Fire Safety;
(N) "Direct supervision," to mean the
				supervisor (blaster) is physically present on the same job site as the person
				loading or firing the explosives;
(O) "Explosives," any chemical compound,
				mixture, or device, the primary or common purpose of which is to function by
				explosion, including, but not limited to, dynamite, black powder, pellet
				powder, initiating explosives, detonators, millisecond connectors, safety
				fuses, squibs, detonating cord, igniter cord, and igniters; includes explosive
				materials such as any blasting agent, emulsion explosive, water gel, or
				detonator. Explosive materials determined to be within the coverage of sections
				319.300
				to
				319.345,
				RSMo shall include all such materials listed in Chapter 40 of Title 18 of the
				United States Code, as amended, as issued at least annually by the Department
				of Justice, Bureau of Alcohol, Tobacco, Firearms and Explosives;
(P) "Firing," causing explosives to be
				detonated by the use of a fuse, electric detonator, or nonelectric shock
				tube;
(Q) "Fire protection
				official," an authorized representative of a municipal fire department, fire
				protection district, or volunteer fire protection association for the area
				where blasting occurs;
(R)
				"Fugitive from justice," any person who has fled from the jurisdiction of any
				court of record to avoid prosecution for any crime or to avoid giving testimony
				in any criminal proceeding. The term shall also include any person who has been
				convicted of any crime and has fled to avoid case disposition;
(S) "Initiation system," components of an
				explosive charge that cause the charge to detonate, such as primers, electric
				detonators, and detonating charge;
(T) "Loading," placing of explosives in a
				hole in preparation for detonation;
(U) "Local government," a city, county, fire
				protection district, volunteer fire protection association, or other political
				subdivision of the state;
(V)
				"Person using explosives," any individual, proprietorship, partnership, firm,
				corporation, company, or joint venture that is required to hold authority to
				receive or use explosives under statutes or regulations administered by the
				U.S. Department of Justice, Bureau of Alcohol, Tobacco, Firearms and Explosives
				and who employs licensed blasters;
(W) "Scaled distance," a value determined by
				dividing the linear distance, in feet, from the blast to a specified location,
				by the square root of the maximum weight of explosives, in pounds, to be
				detonated in any eight- (8-) millisecond period;
(X) "Seismograph," an instrument that
				measures ground vibration and acoustic effects;
(Y) "Stemming," inert material that is placed
				above explosives that have been placed in a blast hole in preparation for
				detonation or vertically between columnar decks of explosives that have been
				placed in a hole in preparation for detonation; and
(Z) "Uncontrolled structure," any dwelling,
				public building, school, church, commercial building, or institutional building
				that is not owned or leased by the person using explosives, or otherwise under
				the direct contractual responsibility of the person using explosives.
