DIN ISO 20712-3:2015-09

This 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 necessary 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. 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. This part of ISO 20712 gives guidance for the selection and use of water safety signs as specified in ISO 20712‑1 and beach 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 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. This standard differs from DIN ISO 20712-3:2010-10 as follows: a) Clause 8 "Tsunami signing system" and Annex E "Examples of tsunami signing system" have been extended; b) the standard has been editorially revised. The underlying International Standard ISO 7010:2011 has been prepared by ISO/TC 145/SC 2 "Graphical symbols - Safety identification, signs, shapes, symbols and colours". On the national level, the Joint Working Committee NA 095-01-06 GA "Sicherheitskennzeichnung" ("Safety identification") at the DIN Standards Committee Safety Design Principles (NASG) is responsible for the processing. The ISO 20712 standard series 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
