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.
