20、4(E)IntroductionThis part of ISO 20712 reflects good practice in the use of water safety signs and beach safety flags. The illustrations show examples of the selection and location of water safety signs and beach safety flags designed to provide information about aquatic hazards and the action neces
21、sary to avoid those hazards.A standardized method of signing with the use of appropriate supplementary text throughout the working and public environment assists the process of education and instruction on the meaning of water safety signs and beach safety flags, and the appropriate actions to take.
22、 The intention of this part of ISO 20712 is to ensure a uniformity of application of water safety signs and beach safety flags which leads to increased familiarity, and therefore improved safety, for the users including visitors and for the general public.The illustrations within this part of ISO 20
23、712 are based on assumptions that some of the people may be unfamiliar with the features of the indoor or outdoor swimming pools or of the beach. The illustrations are not intended to cover every potentially hazardous situation and they should be interpreted as recommendations and not as minimum req
24、uirements.The use of water safety signs and beach safety flags does not replace the need for proper working methods and safety instruction or for training in accident prevention and the actions to be taken in the event of an emergency, or for the provision of lifeguards.This publication does not pur
25、port to include all the necessary provisions of a contract. Users are responsible for its correct application.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
26、 in this part of ISO 20712 where they use the diamond geometric shape for warning signs.

27、r 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 3864-4, it is not intended that these printed copies be used for
28、colour matching. Instead, consult ISO 38644, which provides colorimetric and photometric properties, together with, as a guideline, references from colour order systems.1 ScopeThis part of ISO 20712 gives guidance for the selection and use of water safety signs as specified in ISO 20712-1 and beach
29、safety flags as specified in ISO 20712-2, in aquatic environments. It provides guidance on their location, mounting positions, lighting and maintenance. It also provides guidance on the design and location of multiple signs.This part of ISO 20712 does not apply to traffic signs for use on the public
30、 highway or maritime signalling. It is not applicable to flags for use on firing ranges or to flags used to indicate water quality. It does not cover means of escape signs and their illumination which may be present.NOTE The illustrations in this part of ISO 20712 are as accurate as possible within
31、the limitations of the printing process.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

See ISO 3864-1.4 Guidance for selection and siting of signs and flags4.1 Guidance for risk assessmentSelection and use shall be determined following the results of a
40、 risk assessment. The risk assessment should take into account the following specific issues:a) hazards and associated risks of the aquatic environment;2 ISO 2014 All rights reservedBS ISO 20712-3:2014ISO 20712-3:2014(E)b) regulations or legislation;c) operation and management of the aquatic environ
41、ment;d) users and their foreseeable behaviour.In specific situations, other issues may have to be considered in a risk assessment.NOTE The users can be in unfamiliar environments, not wearing their normal sight correction lenses, or in bare feet.As the result of the risk assessment, a comprehensive
42、statement of requirements should be prepared and used as the basis for the detailed design and specification for the selection and use of signs and flags.4.2 Siting4.2.1 Water safety signs and multiple signsThe siting of water safety signs and multiple signs should allow hazards to be recognized and
43、 appropriate avoiding action to be taken by users.The following matters (issues, factors) should be considered:a) location of hazards and their signage;b) location of entrances/access to facilities;c) location of any other signs;d) location of architectural features, dcor, structures, vegetation or
44、people that could conceal or divert attention from signs;e) lighting level and characteristics under both normal and mains-failure conditions;f) appropriate supplementary text to water safety signs;g) appropriate information on multiple signs.4.2.2 Beach safety flagsThe siting of beach safety flags
45、should allow hazards to be recognized and appropriate avoiding action to be taken by users.The following matters (issues, factors) should be considered:a) nature and location of hazards and their relevant signage;b) zoning or boundaries of aquatic activities;c) location of structures, beach furnitur
46、e or vegetation that could conceal or divert attention from flags;d) location of flag-poles;e) appropriate information on multiple signs, such as an explanation of meaning of flags and the presence or otherwise of a lifeguard service.

47、(E)5 Water safety signs5.1 General requirements for aquatic environments5.1.1 GeneralThe system designer should identify the locations of the hazards.Water safety signs should conform to ISO 20712-1. Where other safety sign meanings are required, these safety signs should conform to ISO 7010. Safety
48、 signs should comply with the colorimetric and photometric requirements given in ISO 3864-4.The required sign height of the safety sign should be determined from the maximum viewing distance under different external illumination conditions and the relevant distance factor z according to Table A.1.Th
49、e following principles should be taken into account when planning water safety signage; signs should:a) be sited conspicuously within the normal field of vision;b) contrast to their surroundings;NOTE The contrast and conspicuity may be increased by the provision of an outer border or by mounting on a sign board with a colour contrasting to the surroundings.c) be visible from any place within the vicinity of the hazard;d) be sited at the same height throughout the aquatic facility, as far as is reasonable;e) take pre
