Consensus is established when, in the judgment of the ANSI Board of Standards review,

12、d is not a part of American national Standard Z359.11-2014.)this standard, national in scope, was developed by an Accredited Standards committee functioning under the procedures of the American national Standards institute, with the American Society of Safety engineers (ASSe) as secretariat.it is in

13、tended that every employer whose operations fall within the scope and purpose of the standard will adopt the guidelines and requirements detailed in this standard.the need for this standards activity grew out of the continuing development of a series of fall protection-relat-ed standards. the focus

14、is to tie the elements of those standards together and provide the tools with which employers may develop the programs that incorporate those elements. this standard also brings together the administrative requirements of those fall protection standards. it should be noted, as in all Z359-series sta

15、ndards, that this standard applies to occupational activities. it does not apply to sports activities such as mountaineering.neither the standards committee, nor the secretariat, states that this standard is perfect or in its ultimate form. it is recognized that new developments are to be expected,

16、and that revisions of the standard will be necessary as the state-of-the-art progresses and further experience is gained. it is felt, however, that uniform guidelines for fall protection programs are very much needed and that the standard in its present form provides for the minimum criteria necessa

17、ry to develop and implement a comprehensive managed fall protection program.The Z359 Committee acknowledges the critical role of design in influencing the use of proper fall protection equipment. Designs which eliminate fall hazards through the proper application of the hierarchy of safety controls

18、are the preferred method for fall protection. Design deficiencies often increase the risk for employ-ees who may be exposed to fall hazards: examples are (1) lack of rail systems to prevent falls from machines, equipment and structures; (2) failure to provide engineered anchorages where use of perso

19、nal fall arrest systems are anticipated; (3) no provision for safe access to elevated work areas; (4) installation of machines or equipment at heights, rather than floor/ground level to preclude access to elevated areas; (5) failure to plan for the use of travel restriction or work positioning devic

20、es. to that end, this series of standards also provides guidance for design considerations for new buildings and facilities.Basic fall safety principles have been incorporated into these standards, including hazard survey, hazard elimination and control, and education and training. the primary inten

21、t is to ensure a proactive approach to fall protection. However, the reactive process of accident investigation is also addressed to ensure that adequate attention is given to causation of falls.the Z359 committee solicits public input that may suggest the need for revisions to this standard.
