10、O (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical co

11、mmittee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electro

12、technical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires app

13、roval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 10333 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 10333

14、-3 was prepared by Technical Committee ISO/TC 94, Personal safety Protective clothing and equipment, Subcommittee SC 4, Personal equipment for protection against falls. ISO 10333 consists of the following parts, under the general title Personal fall-arrest systems: Part 1: Full-body harnesses Part 2

15、: Lanyards and energy absorbers Part 3: Self-retracting lifelines Part 4: Vertical rails and vertical lifelines which incorporate a sliding-type fall arrester Part 5: Connectors The system performance tests will be the subject of a future part 6 to ISO 10333.ISO 10333-3:2000(E) ISO 2000 All rights r

16、eserved v Introduction In cases where the hazard of falling from a height exists and where, for technical reasons or for work of very short duration, safe access cannot be otherwise provided, it is necessary to consider the use of personal fall-arrest systems (PFAS). Such use should never be improvi

17、sed and its adoption should be specifically provided for in the appropriate formal provisions for safety in the work place. PFAS complying with this part of ISO 10333 should satisfy ergonomic requirements and should only be used if the work allows means of connection to a suitable anchor device of d

18、emonstrated strength and if it can be implemented without compromising the safety of the user. Personnel should be trained and instructed in the safe use of the equipment and be observant of such training and instruction. This part of ISO 10333 is based on current knowledge and practice concerning t

19、he use of PFAS that incorporate a full-body harness as specified in ISO 10333-1. This part of ISO 10333 presumes that the manufacturer of the PFAS, subsystems or components will, for the sake of consistency and traceability, operate a quality management system which will comply with national and reg

20、ional regulations in force at the time. Guidance on the form this quality management system may take can be found in ISO 9000 (all parts), Quality management and quality assurance standards.INTERNATIONAL STANDARD ISO 10333-3:2000(E) ISO 2000 All rights reserved 1 Personal fall-arrest systems Part 3:

21、 Self-retracting lifelines 1 Scope This part of 10333 specifies requirements, test methods, instructions for use and maintenance, marking, labelling and packaging, as appropriate, for self-retracting lifelines, including self-retracting lifelines that have an integral-rescue facility. Self-retractin

22、g lifelines are used as a connecting sub-system in personal fall-arrest systems (PFAS), which will be specified in a future International Standard (see ISO 10333-6 in the Bibliography), and are attached to anchor devices that are above the work place. This part of 10333 is applicable only to self-re

23、tracting lifelines limited to single-person use of a total mass not exceeding 100 kg. NOTE Users of PFAS whose total mass (which includes attached tools and equipment) exceeds 100 kg are advised to seek advice from the equipment manufacturers regarding the suitability of the equipment, which may nee

24、d additional testing to take into account the larger mass. This part of 10333 does not specify those additional requirements that would apply when self-retracting lifelines are subjected to special conditions of use (where, for example, there exist unusual limitations concerning access to the place

25、of work and/or particular environmental factors). Thus treatments to ensure the durability of the materials of construction (such as heat treatment, anti-corrosion treatment, protection against physical and chemical hazards) are not specified in this part of 10333, but should comply with appropriate

26、 International Standards or, failing that, with national standards and other specifications dealing with relevant physical characteristics and/or the safety of users. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisi

35、 connected to the SRL, is in post fall-arrest suspension, or has become incapacitated. This may involve the rescuer raising or lowering the worker as appropriate. 3.1.3 energy absorbers integral to the lifeline component designed to dissipate the kinetic energy generated during a fall, which limits
