5、60018-2187 Approved: August 8, 2011 Effective: December 12, 2011 American National Standards Institute, Inc. Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards develo

6、per. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all vi

7、ews and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he/she has approved the standards or not, from manufacturing, marketing, pur

8、chasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstance give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to is

9、sue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretation should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. Caution Notice: This American National Standard may be

Printed in the United States of America American National Standard Foreword (This Foreword is not a part of American National Standard A10.7-2011.) This standard is

13、 one of a series of safety standards that have been formulated by the Accredited 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

14、equipment manufacturers. For the convenience of users, a list of existing and proposed 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 satisf

15、actory by an authority having jurisdiction. 3.4 Authorized; Authorization. Approved 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

16、responsible for approving equipment, an installation or a procedure. 3.6 Barrier. 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 exp

17、losion may cause injury to persons. AMERICAN NATIONAL STANDARD A10.7-2011 13 3.8 Blast Preparation. 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

18、of a borehole, including 50 feet (15.2m) in all directions from the perimeter formed by loaded holes. 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 fe

19、et (9.1m) distance require-ments, as applicable, shall apply in all directions along the full depth 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

20、assists with the design, loading and firing of a blast. May or may not be licensed according to local 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 Bla

21、sting Agent. An explosive material that meets prescribed criteria for insensitivity to initiation. For 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

22、and oxidizer, intended for blasting but not otherwise defined as an explosive. This assumes that the 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

23、 material (blasting agent) as a substance which has mass explosion hazard, but is so insensitive that 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. E

24、quipment (usually a motor vehicle with or without mechanical delivery device) that transports explosive 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

25、by a bullet of 150-grain M2 ball ammunition of nominal muzzle velocity 2,700 feet per second (840m/s), 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

26、 be constructed of materials comparable to the side walls or of other materials that will withstand 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 resis

27、t penetration of 5 out of 5 shots placed independently of each other in an area at least 3 feet by 3 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 amm

28、unition of nominal muzzle velocity 2,700 feet per second (840m/s), fired from a .30 caliber rifle from 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. Wir

29、e used to extend the firing line or leg wires in an electric blasting circuit. AMERICAN NATIONAL STANDARD A10.7-2011 14 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 explosi

30、ve reac-tion such as a rapid combustion that moves through an explosive material at a velocity less than the speed of sound 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 con

31、taining any initiating or primary explosive that is used for initiating detonation. A detonator may not contain more than 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, el

32、ectronic detonators, blasting caps for use with safety fuses, detonating-cord delay connectors and nonelectric instantaneous 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 impinge

33、s upon an “acceptor“ charge. 3.23 Electric Detonator. A detonator designed for, and capable of, initiation by means of an 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 provide

34、s initiation energy for firing the base charge. Electronic detonators differ from other detonators by utilizing an Integrated 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 circui

35、t. Unlike an electric detonator, the igniter or firing device inside an electronic detonator is physically separated from 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. A

36、n explo-sive material containing substantial amounts of oxidizers dissolved in water droplets surrounded by an immiscible fuel or droplets of an immiscible fuel surrounded by water containing substantial amounts of oxidizer. 3.26 Explosive Materials.
