						  holes to be loaded in a blast and the blaster-in-charge of that blast in which
						  the driller describes the conditions of the boreholes that the driller drilled.

						  messages describing borehole conditions or verbal communication in which the
						  driller describes the condition of the boreholes.

						  by the Department under Chapter 210 (relating to blasters' licenses) to
						  detonate explosives and supervise blasting activities.
Blaster-in-charge
-The blaster
						  designated to have supervision and control over all blasting activities related
						  to a blast.
Blasting activity
-The actions
						  associated with the use of explosives from the time of delivery of explosives

						  loading, stemming, wiring or connecting, detonating, and all necessary safety,
						  notification and monitoring measures.
Building
-A structure that is designed
						  for human habitation, employment or assembly.
Charge weight
-The weight in pounds of
						  an explosive charge.
Concertina razor wire
-Razor wire that

						  having a minimum of 101 coils of wire to 50 linear feet.
Cube root scaled distance
						  (Ds1/3)
-A value calculated by using the
						  formula Ds1/3 = D/(cube root) W, where actual
						  distance (D) in feet measured in a horizontal line from the blast site to the
						  nearest building or structure not owned or leased by the blasting activity
						  applicant, the permittee or their customers, is divided by the cube root of the
						  maximum weight of explosives (W) in pounds detonated per delay period of less
						  than 8 milliseconds. Cube root scaled distance is used to estimate airblast
						  levels.
Delay interval
-The designed time
						  interval, usually in milliseconds, between successive detonations.
Detonator
-
(i) A device containing an initiating or
						primary explosive that is used for initiating detonation of
						explosives.
(ii) The term includes
						electric blasting caps of instantaneous and delay types, blasting caps for use
						with safety fuses, detonating cord, delay connectors, and nonelectric
						instantaneous and delay blasting caps.
Explosives
-Any chemical compound,
						  mixture or device, the primary or common purpose of which is to function by
						  explosion. The term includes dynamite and other high explosives, black powder,
						  pellet powder, initiating explosives, detonators, safety fuses, squibs,
						  detonating cord, igniter cord and igniters. The term includes all items in the
						  "List of Explosive Materials" provided for in
						  27 CFR
						  555.23 (relating to list of explosive
						  materials).
FMCSA inspection
-The inspection
						  required by the Federal Motor Carrier Safety Administration in
						  40 CFR
						  396.3 (relating to inspection, repair, and
						  maintenance).
Flyrock
-Overburden, stone, clay or
						  other material cast from the blast site through the air or along the ground, by
						  the force of a blast, and which travels to one of the following areas:
(i) Beyond the blast area.
(ii) Beyond permit boundaries on blasting
						operations on mining permits issued under the Surface Mining Conservation and
						Reclamation Act (52 P.S. §§
													1396.1-1396.19b) or the Noncoal Surface
						Mining Conservation and Reclamation Act (52 P.S.
						§§
													3301-3326).
Indoor magazine
-A magazine located
						  entirely within a secure intrusion-resistant and theft-resistant building which
						  is primarily used for commercial or industrial purposes.
Inner perimeter security
-Measures
						  taken to increase the intrusion resistance and theft resistance of a magazine
						  that encircles an individual or a group of magazines. These measures lie within
						  the outer perimeter security measures.

						  value calculated by using the formula Ds = D/(square root) W, where actual
						  distance (D) in feet, measured in a horizontal line from the blast site to the
						  nearest building or structure, neither owned nor leased by the blasting
						  activity permittee or its customer, divided by the square root of the maximum
						  weight of explosives (W) in pounds, that is detonated per delay period of less
						  than 8 milliseconds. Square root scaled distance is used to estimate ground
						  vibration.
