Water safety signs and beach safety flags — Part 2: Specifications for beach safety flags — Colour, shape, meaning and performance
ISO 20712-2:2007 specifies requirements for the shape and colour of beach safety flags for the management of activities on coastal and inland beaches, to be used for giving information on wind and water conditions and other hazardous conditions, and to indicate the location of swimming and other aquatic activity zones extending from the beach into the water. It also specifies the colorimetric and photometric properties and the physical properties, including strength and colour fastness, of the materials from which beach safety flags are to be made. It is not applicable to flags for use on firing ranges or to flags for use to indicate water quality or to signalling used for maritime traffic.

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 20712-2 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 20712-2:2007(E)
Introduction
There is a need to standardize a system of giving safety information 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 beach safety flags 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.
NOTE Some countries’ statutory regulations may differ in some respects from those given in this part of ISO 20712.
