2、 Work - Safety Requirements Secretariat National Safety Council Approved October 30,1987 American National Standards Institute, Inc Abstract This standard establishes the safety requirements for ceramic tile, terrazzo, and marble work during handling and installation on all types of construction, in
3、cluding heavy construction such as bridges and tunnels. American Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for National w roval have been met by the standards developer. Standard c onsensus is establis
4、hed 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 views and objections be cons
5、idered, 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 has approved the standards or not, from manufacturing, marketing, purchasing, or using products, pr
6、ocesses, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an A
7、merican National Standard in the name of the American National Standards Institute. Requests for interpretations should be ad- dressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at a
8、ny time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard.

This American National Standard provides detailed information for subcontractors and their employees on the safety requirements for
11、 construction site installations of ceramic tile, terrazzo, and marble. It applies to all types of structures - residential, commercial, and industrial; to heavy construction such as bridges and tunnels; and to both interior and exterior work. The standard represents the consensus of a cross section
12、 of the ceramic tile, terrazzo, and marble industries and should form the basis for construction safety regulations for ceramic tile, terrazzo, and marble work when established by federal, state, and municipal agencies, as well as for safety standards adopted by insurance companies and trade associa
13、tions. Work on this standard was begun by the Southern Tile, Terrazzo and Marble Contractors Association. By its invitation, all of the national organizations in the ceramic tile, terrazzo, and marble trades participated in the preparation and development of the standard. The fist edition was approv
14、ed by American National Standards Committee on Safety in Con- struction and Demolition Operations, AlO, on February 22, 1974, and published in 1977. This first edition has now been revised to represent the safety standards needed in present operations. This standard is one of a series of safety stan
15、dards that have been formulated by Commit- tee AIO. It is expected that the standards in the A10 series will find a major application in industry, and will serve as a guide to contractors, labor, and equipment manufacturers. For the con- venience of users, existing and proposed standards in the A10
16、series for safety requirements in construction and demolition operations are as follows: A10.3 Powder Actuated Fastening Systems A 10.4 Personnel Hoists AIO.S Material Hoists A10.6 Demolition A10.7 Transportation, Storage, Handling, and Use of Commercial Explosives and Agents in the Construction Ind

If these standards are adopted for government use, the reference to other national codes or standards in the individual volumes may be changed to refer to the corresponding regulations of the gov- ernment

The A10 Committee shall approve the interpretation before a response is sent to the inquirer. (No one but the A10 Committe
23、e is authorized to provide any interpretation of this standard.) The A10 Committee solicits comments on and criticisms of the requirements of the standards. The standards will be revised from time to time to provide for new develop- ments. Suggestions for improvement of this standard will be welcome
