 IMPORTANT The colours represented in this annex can be neither viewed on screen nor printed as true representations. Although the signs and symbols in this annex have been reproduced to correspond (with an acceptable tolerance as judged by the naked eye) to the requirements of standard ISO 3864-4, it is not intended that the signs and symbols shown in this annex be used for colour matching.

For a definitive version of all safety symbols in this annex, please consult standard ISO 7010 and the ISO Online Browsing Platform ( For a definitive version of all fire control symbols in this annex, please consult standard ISO 17631. These are the source documents from which to create safety and fire control plans signs.

For the purposes of this document, the terms and definitions given in standards ISO 17724, ISO 24409-1, and the following apply.

2.1 Fire control signs

Signs for specialists, used to identify and locate fire control equipment, not designed according the rules for safety signs.

Note 1 to entry: These signs are related to the symbols in standard ISO 17631; see 3.1 h) below.

2.2 Image content

Written description of the elements of a graphical symbol or safety sign and their relative disposition.

[ISO 17724:2003, 38]

2.3 Referent

Idea or object that a graphical symbol is intended to represent.

[ISO 17724: 2003, 61]

2.4 Safety sign

Sign giving a general safety message, obtained by a combination of a colour and geometric shape and which, by the addition of a graphical symbol, gives a particular safety message.

3 Categorization of shipboard signs

3.1 Signs in this standard are categorized according to their function as follows:

  • a) MES means of escape signs which provide escape route identification.

  • b) EES emergency equipment signs which provide use and location of first aid facilities and portable safety equipment.

  • c) LSS life-saving systems and appliances signs which provide use and location of life-saving systems and appliances.

  • d) FES fire-fighting equipment signs which provide use and location of fire-fighting equipment.

  • e) PSS prohibition signs which provide prohibited actions.

  • f) WSS hazard warning signs which provide identification of hazards to avoid.

  • g) MSS mandatory action signs which provide mandatory notices and instructions.

  • NOTE The PSS, WSS and MSS categories are based on the P, W and M categories of standard ISO 7010.

  • h) SIS safety and operating instructions for trained personnel.

3.2 Table 1 summarizes the standardized shipboard safety signs used in workplaces and public areas in terms of functional category, referent number, referent, graphical symbol as well as geometric shape and colour.
