3、I Technical Report, the ANSI Board of Standards Review confirms that the requirements for due process, consensus, balance and openness have been met by AMT - The Association For Manufacturing Technology (the ANSI-accredited standards developing organization). American National Standards and Technica

4、l Reports are developed through a consensus process. Consensus is established when 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

5、objections be considered, and that a concerted effort be made toward resolution. This process brings together volunteers andlor seeks out the views of persons who have an interest in the topic covered by this publication. While AMT administers the process and establishes procedures to promote fairne

6、ss 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 information or the soundness of any judgments contained in its standards or guidelines. American National Standards and Technical Reports are

7、promulgated through ANSI for voluntary use; their existence does not in any respect preclude anyone, whether they have approved the standardsltechnical reports or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to these documents. However, u

8、sers, distributors, regulatory bodies, certification agencies and others concerned may apply American National Standards or Technical Reports as mandatory requirements in commerce and industry. The American National Standards Institute does not develop standards or technical reports and will in no c

9、ircumstances 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. Requests for interpretations should be addressed to the Se

26、ittee consisting of professionals that are involved in manufacturing, safety, design and ergonomics to revise the 1993 technical report giving guidelines for the application of ergonomic principles to machine tools during the design, installation and use phases. The revised guideline is a significan

27、t change from the 1993 guideline. This guideline is intended to be a hands-on design reference to help reduce or eliminate work-related factors associated with musculoskeletal disorders (MSDs) and injuries associated with human error. This guideline offers an ergonomic risk assessment flow chart and

28、 risk reduction hierarchy referencing ANSI BI 1 .TR3. This guideline is not intended to provide specific decisions as to risk acceptability nor replace existing ergonomic risk assessment tools now used within existing ergonomic programs. The guideline does offer ergonomic design references for stren

29、gth, forceful exertions, posture, control and display selection and design, environmental exposures such as temperature, vibration, noise and illumination. Three sample checklists are offered in Annex G to assist with prioritizing risk factors for continuous improvements during design, installation

30、and use. In addition, Lifting, Lowering, Pushing, Pulling and Carrying Tables are provided in Annex C. The data in these tables were developed by Liberty Mutual and have been in use since 1978 (Snook 1978; Snook and Ciriello 1991). The Liberty Mutual Tables in Annex C differ from all previously publ

31、ished versions of the “Snook” Tables; e.g., population percentage is provided rather than maximum acceptable weights and forces. These tables are easy to use and flexible but ergonomic training as discussed in clause 9 is recommended before utilizing them. Metric units While the body of this Technic

32、al Report conforms to the BI 1 ASC Metric Policy (soft metric units, followed by parenthetical hard english units), space precludes conformance to this policy in some portions, e.g., many of the Annex tables.

Integrating ergonomic concepts early in the design process should maximize the impact and cost effectiveness of ergonomic interventions during the design process. The goal of this document is to provide guidance on th

38、e practical application of ergonomic principles in order to avoid work-related injuries and musculoskeletal disorders (MSDs), increase productivity, and improve product quality. This document is directed towards technicians, engineers, designers, and safety and health practitioners who deal with gen

39、eral ergonomic issues related to machine tools. It is not intended to replace in-depth analysis by qualified and experienced ergonomists. 2 Ref ere n ces The following references were either used as a basis for developing this document, or they represent other good reference sources that may be cons
