Foreword
ISO (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 committee
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 electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Safety identification, signs, shapes, symbols and colours.
This third edition cancels and replaces the second edition (ISO 3864-3:2012), which has been technically
revised.
The main changes are as follows:

Introduction
Graphical symbols in safety signs are used for a wide range of purposes. There is a need to standardize the
principles for creating these graphical symbols to ensure visual clarity, to maintain consistency and thereby
to improve recognition and comprehension. The principles set out in this document specify the design
criteria by which graphical symbols are judged for standardization and publication in ISO 7010.
Graphical symbols used in safety signs are not always intuitively understood. Often training can be necessary
to inform people about the meaning of a graphical symbol. Such training can take place by including the
meaning of a graphical symbol in operation manuals, company bulletins and training programme materials,
as well as by using supplementary text with the safety sign.

as well as translations of the referents, can be found at https://www.iso.org/tc145/sc2.

4 Designing graphical symbols for use in safety signs
Before designing a graphical symbol the designer shall:
— develop a clear and unambiguous description of the hazard that the graphical symbol is intended to
address;
— confirm that a new graphical symbol for use in a safety sign is required (i.e. confirm that a suitable
graphical symbol does not already exist; see Clause 5);
— identify the safety message that the safety sign is intended to convey;
— define the characteristics of the target group, including their general skill and ability to understand the
information that the particular safety sign is intended to convey, and design the graphical symbol for
that group;
— assign a meaning and function to the safety sign in accordance with Clause 6;
— identify the type

EXAMPLE The fire determinant, when used with the graphical symbol for a hose reel, conveys the meaning “fire

4 Designing graphical symbols for use in safety signs
Before designing a graphical symbol the designer shall:
— develop a clear and unambiguous description of the hazard that the graphical symbol is intended to
address;
— confirm that a new graphical symbol for use in a safety sign is required (i.e. confirm that a suitable
graphical symbol does not already exist; see Clause 5);
— identify the safety message that the safety sign is intended to convey;
— define the characteristics of the target group, including their general skill and ability to understand the
information that the particular safety sign is intended to convey, and design the graphical symbol for
that group;
— assign a meaning and function to the safety sign in accordance with Clause 6;
— identify the type of the safety sign required in accordance with 7.1.
Consideration should be given as to the types of safety sign for which the graphical symbol can be appropriate
and to the design implications such multiple applicability can have. For example, a graphical symbol for use
in a mandatory action sign can be adversely affected by the diagonal bar of a prohibition sign. Also, the
restricted space within the triangle of a warning sign can adversely affect the graphical symbol originally
designed for a prohibition sign.
During the creation process, the designer shall follow the criteria given in Clause 7.
Designers are strongly recommended to use the guidelines set out in Annex A.
5 Review of existing International Standards
The designer shall determine:
— whether a safety sign incorporating a graphical symbol conveying the required meaning is specified in
ISO 7010;
— in cases where a safety sign incorporating a graphical symbol conveying the required meaning is not
specified in ISO 7010, whether there is a registered graphical symbol conveying the required meaning;
— whether registered graphical symbols with similar meanings can be adapted or combined to form the
graphical symbol for the new safety sign;
— whether there are standardi
