14、n 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. The purpose of this standard is to specify requirements for the design and perfor-mance of a

15、ctive fall-protection systems, including travel-restraint and vertical and horizontal fall-arrest sys-tems. It is intended 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 original need for

16、 the Z359.6 standard grew out of the continuing development of a series of fall protec-tion-related standards, known as the Z359 Fall Protection Code. The purpose of the fall protection code is to provide employers with tools that can be used to develop fall protection programs for employee protecti

17、on. This is the second edition of Z359.6, the original was published in 2009. This standard, as for all Z359-series standards, applies only to occupational activities. It is not intended to apply to sports activities, such as mountaineering. It is intended that this standard provide clarity to the O

18、ccupational Safety “should” is used to ex-press a recommendation, which is advised but not required; and “may” is used to express an option, which is permissible within the limits of the stan-dard. Notes to tables and figures are considered part of the table or figure and may be written as re-quirem

19、ents. Legends to equations and figures are considered requirements.1.2.8 E-column commentary that accompanies sections does not include requirements or alterna-tive requirements; the purpose of the E-column is to separate requirements of the standard from the explanatory commentary and informative m

20、aterial.1.3 Exceptions.1.3.1 This standard does not specify design or performance requirements for active fall protec-tion equipment components or systems when there exists a standard, within the ANSI/ASSE Z359 Fall Protection Code, that details qualification and veri-fication testing for the compon

21、ent or system. Quali-fication and verification testing of ANSI/ASSE Z359 components and systems shall meet the require-ments of the relevant component or system stan-dard and the requirements of ANSI/ASSE Z359.7. Components or systems shall not be marked as be-ing in compliance with this standard as

22、 a substitute when another relevant ANSI/ASSE Z359 standard exists.1.3.2 This standard does not cover the design of passive fall protection systems, such as guardrails and safety nets, except when passive systems are also designed to serve as an anchorage for an ac-tive fall protection system.1.3.3

23、This standard does not cover the design of positioning systems.E1.3.1 This standard is intended for the design of complete active fall protection systems. Therefore, it is recommended that this standard not be referenced on specific fall protection products. It is anticipated that this standard may

24、be used to incorporate equipment components into the design of active fall protection systems prior to an acceptable product standard being created for the equipment components proper use.This is an ASSE-produced standard.

26、 fall protection systems. It does not cover the determination of design strength of components and anchorages. Design strength may be determined by empirical testing, numerical techniques or by design specifications, including but not limited to ACI 318, ACI 530, AISC 360 and NDS, for the materials

27、and structural systems be-ing used.1.3.5 The design of active systems for users heavier than 310 pounds (140kg) or lighter than 130 pounds (59kg) is outside the scope of this standard.1.4 Interpretations. Requests for interpretations of this standard shall be in writing and addressed to the Secretar

DRAWINGS, SPECIFICATIONS AND PROCE-DURE REQUIREMENTS3.1 General. An active fall protection system meet-ing the requi

29、rements of this standard shall have drawings, specifications and procedures, as appli-cable, prepared by or under the supervision of a qualified person.3.2 Drawing and Specification Requirements.3.2.1 Construction documents shall describe the components of an active fall protection system that are t

30、o be fabricated, assembled and installed. Drawings and specifications contained within the construction documents shall include, but not be limited to:3.2.1.1 A statement defining the type of active fall protection system and that the design meets crite-ria established by this standard. If exception

31、s to this standard are made in the design, then they shall be clearly stated.E3.1 Many jurisdictions require that individuals who design or evaluate physical structures be registered with the jurisdiction as a professional engineer.E3.2.1.1 Types of active fall protection systems include travel rest
