16、1001, User=ZhaoNot for Resale, 05/02/2012 00:36:12 MDTNo reproduction or networking permitted without license from IHS-,-,-Foreword (This Foreword is not a part of American National Standard A10.7-2011.) This standard is one of a series of safety standards that have been formulated by the Accredited
17、 Standards Committee on Safety in Construction and Demolition Operations, A10. It is expected that the standards in the A10 series will find a major application in industry, serving as a guide to contractors, labor, and equipment manufacturers. For the convenience of users, a list of existing and pr
18、oposed standards in the A10 series for Safety Requirements in Construction and Demolition Operations follows. A10.1 Pre-Project/Pre-Task Safety Approval. Sanctioned, endorsed, accredited, certified, or accepted as satisfactory by an authority having jurisdiction. 3.4 Authorized; Authorization. Appro
19、ved or assigned by the employer to perform a specific type of duty or duties or to be at a specific location or locations at the jobsite. 3.5 Authority Having Jurisdiction. The governmental agency, office or individ-ual responsible for approving equipment, an installation or a procedure. 3.6 Barrier
20、. A material object that separates, keeps apart or demarcates in a conspicuous manner such as cones, a warning sign or tape. 3.7 Blast Area. The area in which concussion (shock wave), flying material or gases from an explosion may cause injury to persons. Copyright American Society of Safety Enginee

22、Drilling, hole inspection, loading explosive charges, installing systems for initiation and confinement of the blast. 3.9 Blast Site. The area where explosive materials are handled during the loading of a borehole, including 50 feet (15.2m) in all directions from the perimeter formed by loaded holes
23、. A minimum of 30 feet (9.1m) may replace the 50 feet (15.2m) requirement if the perimeter for loaded holes is marked and separated from non-blast site areas by a barrier. The 50 feet (15.2m) or 30 feet (9.1m) distance require-ments, as applicable, shall apply in all directions along the full depth
24、of the borehole. In underground operations, at least 15 feet (4.6m) of a solid rib, pillar or broken rock can be substituted for the 50 foot (15.2m) distance. 3.10 Blaster. A qualified individual who assists with the design, loading and firing of a blast. May or may not be licensed according to loca
25、l regulations. May be synonymous with Shot Firer. 3.11 Blaster-in-Charge. The blaster who is in charge of and responsible for the design, loading and firing of a blast at a specific job site. 3.12 Blasting Agent. An explosive material that meets prescribed criteria for insensitivity to initiation. F
26、or storage, CFR Title 27, Part 555, of the Bureau of Alcohol, Tobacco, Firearms and Explosives of the Department of the Justice defines a blasting agent as any material or mixture, consisting of fuel and oxidizer, intended for blasting but not otherwise defined as an explosive. This assumes that the
27、 finished product, as mixed for use or shipment, cannot be detonated by means of a No. 8 test blasting cap when unconfined. For transportation, CFR Title 49, Part 173.50, defines Class 1, Division 1.5 material (blasting agent) as a substance which has mass explosion hazard, but is so insensitive tha
28、t there is very little probability of initiation or of transition from burning to detonation under normal conditions in transport. 3.13 Blasting Cap. See Detonator. 3.14 Bulk-Mix Delivery Equipment. Equipment (usually a motor vehicle with or without mechanical delivery device) that transports explos
29、ive materials in bulk form for mixing, or for loading directly into blast holes, or both. 3.15 Bullet-Resistant Construction. Magazine walls or doors of construction that are resistant to penetration by a bullet of 150-grain M2 ball ammunition of nominal muzzle velocity 2,700 feet per second (840m/s
30、), fired from a .30 caliber rifle at a right angle to the wall or door, from a distance of 100 feet (31m). When a magazine ceiling or roof is required to be bullet-resistant, the ceiling or roof shall be constructed of materials comparable to the side walls or of other materials that will withstand
31、penetration when the bullet described above is fired at an angle of 45 degrees to the surface. Tests to determine bullet-resistance shall be conducted on test panels or empty magazines that will resist penetration of 5 out of 5 shots placed independently of each other in an area at least 3 feet by 3
32、 feet (0.9m x 0.9m). Examples of construction that meet this definition are given in 6.5.1. 3.16 Bullet-Sensitive Explosive Ma-terial. Explosive material that can be detonated by 150-grain M2 ball ammunition of nominal muzzle velocity 2,700 feet per second (840m/s), fired from a .30 caliber rifle fr
33、om a distance of 100 feet (31m) when the test material, at 70 to 75 Fahrenheit (21.1 to 23.9 Celsius), is placed against a backing material of half-inch (1.77cm) steel plate. 3.17 Connecting Wire. Wire used to extend the firing line or leg wires in an electric blasting circuit. Copyright American So

35、3.18 Conveyance. Any unit for transporting explosives or blasting agents including, but not limited to, trucks, trailers, rail cars, barges and ships. 3.19 Deflagration. An explosive reac-tion such as a rapid combustion that moves through an explosive material at a velocity less than the speed of so
36、und in the material. 3.20 Detonating Cord. A flexible cord, containing a center core of high explosive that can be used to initiate other explosives. 3.21 Detonator. Any device containing any initiating or primary explosive that is used for initiating detonation. A detonator may not contain more tha
37、n 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, electronic detonators, blasting caps for use with safety fuses, detonating-cord delay connectors and nonelectric instantan
38、eous and delay blasting caps that use detonating cord, shock tube or any other replacement for electric leg-wires. 3.22 Donor. An exploding charge producing an impulse that impinges upon an “acceptor“ charge. 3.23 Electric Detonator. A detonator designed for, and capable of, initiation by means of a
39、n electric current. 3.24 Electronic Detonator. A detona-tor that utilizes stored electrical energy as a means of powering an electronic timing delay element/module and that provides initiation energy for firing the base charge. Electronic detonators differ from other detonators by utilizing an Integ
40、rated Circuit (IC) or an Application Specific Integrated Circuit (ASIC) to provide millisecond precise timing as well as a level of communication and control over the firing circuit. Unlike an electric detonator, the igniter or firing device inside an electronic detonator is physically separated fro
41、m the leads by a circuit board or electronic assembly. See IME SLP-17 for more information on the differences between electric and electronic detonators. 3.25 Emulsion Explosive. An explo-sive material containing substantial amounts of oxidizers dissolved in water droplets surrounded by an immiscibl
42、e fuel or droplets of an immiscible fuel surrounded by water containing substantial amounts of oxidizer. 3.26 Explosive Materials. These include explosives, blasting agents and detonators. The term includes, but is not limited to, dynamite and other high explosives; slurries, emulsions and water gel
43、s; black powder and pellet powder; initiating explosives; detonators (blasting caps); safety fuses; squibs; detonating cords; igniter cords and igniters. A list of explosive materials determined to be within the coverage of 18 U.S.C. Chapter 40, “Importation, Manufacture, Distribution and Storage of
44、 Explosive Materials,” is issued at least annually by the Director of the Bureau of Alcohol, Tobacco, Firearms and Explosives of the Department of Justice. The U.S. Department of Transportation classification of explosive materials used in commercial blasting operations is not identical to the statu
45、tory definitions of the Organized Crime Control Act of 1970, Title 18 U.S.C., Section 841. To achieve uniformity in transportation, the definitions of the U.S. Department of Transportation in CFR Title 49, Parts 1-999 subdivide these materials as shown in the following table: Copyright American Soci
