ISO 20712-1:2008

Water safety signs and beach safety flags — Part 1: Specifications for water safety signs used in workplaces and public areas

ISO 20712-1:2008 prescribes water safety signs intended for use in connection with the aquatic environment. It is intended for use by owners and operators of aquatic environments and by manufacturers of signs and equipment. However, it is not applicable to signalling used for maritime traffic. The shape and colour required to be used for safety signs, as prescribed by ISO 3864-1, are given together with the graphical symbols contained within each sign. The water safety sign originals meet the design criteria of ISO 3864-3. ISO 20712-1:2008 specifies the water safety sign originals that may be scaled for reproduction and application purposes. ISO 20712-1:2008 includes water safety signs which require that supplementary text signs be used in conjunction with these water safety signs to improve comprehension.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 20712-1 was prepared by Technical Committee ISO/TC 145, Graphical symbols, Subcommittee SC 2,
Safety identification, signs, shapes, symbols and colours.
ISO 20712 consists of the following parts, under the general title Water safety signs and beach safety flags:
⎯ Part 1: Specifications for water safety signs used in workplaces and public areas
⎯ Part 2: Specifications for beach safety flags — Colour, shape, meaning and performance
⎯ Part 3: Guidance for use

ISO 20712-1:2008(E)
Introduction
There is a need to standardize a system giving safety information related to aquatic activity that relies as little
as possible on the use of words to achieve understanding.
Continued growth in international trade, travel and mobility of labour requires a common method of
communicating safety information.
Lack of standardization may lead to confusion and perhaps accidents.
The use of standardized safety signs does not replace proper work methods, instructions and accident
prevention training and/or measures. Education is an essential part of any system that provides safety
information.
This part of ISO 20712 is intended to be used by all Technical Committees within ISO charged with
developing specific safety signing in places of aquatic activity to ensure that there is only one safety sign for
each safety meaning. It is also intended that this part of ISO 20712 be revised regularly to include safety signs
as they are standardized by ISO, and which conform to the principles given in ISO 3864-1 and the design
criteria given in ISO 3864-3.
NOTE 1 Some countries' statutory regulations may differ in some respect from those given in this part of ISO 20712.
NOTE 2 Some countries may differ in some respect from the requirements given in this part of ISO 20712 in that they
use the diamond geometric shape for warning signs.

IMPORTANT — The colours represented in the electronic file of this part of ISO 20712 can be neither
viewed on screen nor printed as true representations. Although the copies of this part of ISO 20712
printed by ISO have been produced to correspond (with an acceptable tolerance as judged by the
naked eye) to the requirements of ISO 3864-1, it is not intended that these printed copies be used for
colour matching. Instead, consult ISO 3864-1, which provides colorimetric and photometric properties,
together with, as a guideline, references from colour order systems.
1 Scope
This part of ISO 20712 prescribes water safety signs intended for use in connection with the aquatic
environment. It is intended for use by owners and operators of aquatic environments and by manufacturers of
signs and equipment. However, it is not applicable to signalling used for maritime traffic.
The shape and colour required to be used for safety signs, as prescribed by ISO 3864-1, are given together
with the graphical symbols contained within each sign. The water safety sign originals meet the design criteria
of ISO 3864-3.
This part of ISO 20712 specifies the water safety sign originals that may be scaled for reproduction and
application purposes.
This part of ISO 20712 includes water safety signs which require that supplementary text signs be used in
conjunction with these water safety signs to improve comprehension.
NOTE The criteria of acceptability adopted by ISO/TC 145/SC 2 are given on website www.iso.org/tc145/sc2.

4.3 Categorization of water safety signs
Water safety signs are categorized according to their function as follows:
⎯ E is the category for means of escape and emergency equipment signs (safe condition signs);
⎯ M is the category for mandatory action signs;
⎯ P is the category for prohibition signs;
⎯ W is the category for warning signs.
Table 2 summarizes the standardized safety signs used in workplaces and public areas in terms of function
category, graphical symbol and geometric shape and colour as specified in ISO 3864-1.

ISO 20712-1:2008(E)
5 Standardized water safety signs
Tables 3 to 6 give safety sign originals in a uniform 70 mm size with corner marks to enable accurate
enlargement and reduction scaling. The sign illustrations are shown without borders in order to allow for
consistent reproduction scaling, though the use of borders is encouraged as defined by ISO 3864-1. The
safety signs should be reproduced exactly as shown in Tables 3 to 6. However some degree of graphical
modification is permitted when cultural differences or special application formats need to be considered,
provided the original meaning is retained and comprehension of the sign is maintained. Consistent
reproduction and use of these safety signs will lead to a progressively improved degree of comprehension at
the international level.
In cases where the orientation of the symbol is not essential to its meaning, the orientation may be changed.
A graphical symbol may be depicted in outline or filled-in form.
Tables 3 to 6 present the safety sign originals according to their category as follows:
⎯ E Means of escape and emergency equipment signs (safe condition signs) see Table 3
⎯ M Mandatory action signs see Table 4
⎯ P Prohibition signs see Table 5
⎯ W Warning signs see Table 6
Tables 3 to 6 also give a description of the application used for each safety sign.
