LIVE WORKING –
TERMINOLOGY FOR TOOLS, EQUIPMENT AND DEVICES
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60743 has been prepared by IEC technical committee 78: Live
working.
This second edition cancels and replaces the first edition, published in 1983, and its
amendment 1 (1995), and constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
78/393/FDIS 78/403/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.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
The committee has decided that the contents of this publication will remain unchanged until 2006.
At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

permits identification of the tools, equipment and devices and standardizes their names.
1.2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.

2 General terms
2.1 Live working and methods
2.1.1

activity in which a worker makes contact with energized or charged live parts or penetrates
inside a live working zone with either parts of his or her body or with tools, equipment or
devices being handled
NOTE 1 Examples of live working include maintenance, connection and disconnection operations.
NOTE 2 Live working is performed using specific methods: hot stick working, insulating glove working and bare

NOTE 2 In some countries, particularly in the United Kingdom, it is a permitted option to use the term « plastics »
as the singular form as well as the plural form.
[ISO 472]

nominal voltage calculated in accordance with IEC 61472, and the selected ergonomic distance appropriate to the
work being undertaken.
NOTE 2 “Appropriate tools” are tools for live working suitable for the maximum nominal voltage of the live parts.
