AMERICAN NATIONAL STANDARDS By approving this American National Standard, the ANSI Board of Standards Review confirms that the requirements for due process, consensus, balance and openness hav

4、e been met by AMT The Association For Manufacturing Technology (the ANSI-accredited standards developing organization). American National Standards are developed through a consensus process. Consensus is established when substantial agreement has been reached by directly and materially affected inte

5、rests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward resolution. This process brings together volunteers and/or seeks out the views of persons who

6、 have an interest in the topic covered by this publication. While AMT administers the process and establishes procedures to promote fairness in the development of consensus, it does not write the document and it does not independently test, evaluate or verify the accuracy or completeness of any info

7、rmation or the soundness of any judgments contained in its standards or guidelines. American National Standards are promulgated through ANSI for voluntary use; their existence does not in any respect preclude anyone, whether they have approved the standards or not, from manufacturing, marketing, pur

8、chasing, or using products, processes, or procedures not conforming to the standards. However, users, distributors, regulatory bodies, certification agencies and others concerned may apply American National Standards as mandatory requirements in commerce and industry. The American National Standards

9、 Institute does not develop standards and will in no circumstances give an interpretation of an American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requ

10、ests for interpretations should be addressed to the Secretariat (AMT).

Recognizing the uniqueness of ironworkers and the need for a safety standard for them, Accredited Standards Committee B11 on Safety Standards for Machine Tools est

21、ablished Subcommittee B115 in 1972, to develop the safety requirements for this equipmenL The first standard wu approved by ANSI on September 18, 1975, and reaffirmed on December 1, 1981. For the most part, this standard represents a minor revision of the original document by incorporating cbanges t

22、hat update the standard with cmrent references to other American National Standards and their illustrations, and the latest ANSI Style Manual. Producing a workable safety standard treating the construction, safeguarding, care, and use of ironworkers is complicated by the wide variety and sizes of ir

23、onworkers manufactured and in use, and by the infinite combinations of methods and opemtions used to produce parts. Safeguarding the multiple work stations for the limitless variety of workpiece cross sections is fmther complicated by the need to preserve the flexibility and universal application of

24、 iron workers-Recognizing the difficulty in defining specific guarding requirements for all applications of ironworkers without dettacting from their productivity and fleXJ.“bility, the committee ap proached its primary objective of eliminating injmies to personnel associated with ironworkers from f

25、our directions: (1) Eliminating by design cerl3in recognized construction hazards and establishing standard approaches to design so that the machines available from competitive manufacturers will have similar operational and conarol characteristics. (2) Safeguarding the point of opei3lion to protect

26、 personnel should they inadvertently expose themselves to hazards at the point of operation. (3) Eliminating by design, procedure, and process the necessity of having the operator place his hands or fingers within the point of opemtion at any time the particular work station bas not been made inoper

27、ative, thus minimizing his exposure to point-of-operation hazards. (4) Establishing guidelines for general training and specific jorelated instructions for eliminating unsafe practices and procedures. To implement these requirements, responsibilities have been assigned to the manufacturer, the recon

28、structor, the modifier, the employer, the employee, and the owner. To assist all persons concerned in complying with the requirements of this standard, all explanatory information has been placed in the right column, adjacent to the requirements to which it applies. Recognizing the difficulty of upd

29、ating equipment immediately after the approval date of the ANSI B 115-1975 standard, a three-year period was suggested before the applicable construc tion requirements of this standard become effective for former installations. All grace periods have long since expired. . Suggestions for improvement
