  (9)  "Deck", charge of explosives separated from other charges by stemming;

  (10)  "Delay period", the time delay provided by blasting caps which permits firing of bore holes in sequence;

  (11)  "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;

  (12)  "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 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;

  (13)  "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 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;

  (21)  "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 millisecond period;

  (22)  "Seismograph", an instrument that measures ground vibration and acoustic effects;

  (23)  "Spacing", the distance between adjacent bore holes;

  (24)  "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;

  (25)  "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.
