The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61477 has been prepared by IEC technical committee 78: Live working. This second edition of IEC 61477 cancels and replaces the first edition published in 2001, its Amendment 1 (2002) and Amendment 2 (2004). The document 78/772/FDIS, circulated to the National Committees as Amendment 3, led to the publication of the new edition. The text of this standard is based on the first edition, Amendment 1, Amendment 2 and the following documents: FDIS Report on voting 78/772/FDIS 78/786/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

Where National regulations are in force to dictate the conditions of utilization of tools, devices and equipment for live working, these can be more stringent than the minimum requirements of this standard.

It provides the type of information which is useful to skilled persons in order to make the use of tools, devices and equipment safer. This type of information includes: the characteristics of tools, devices and equipment; their conditions for use; their conditions for maintenance; their conditions for storage and transportation. Such information may be given in standards, manufacturers instructions for use and in internal regulations set forth by companies for their own employees. Such information should be completed by work methods, which are excluded from the scope of this standard. In this standard, the word tool(s) is used for “tools, devices and equipment for live working“ unless otherwise specified. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
