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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction
This document has been developed in order to standardize graphical symbols used in shipborne
computer-based incident response systems. Typically, incident response systems are used in
emergency situations and concise and intuitive representation of information is very important. Well-
designed standard graphical symbols can avoid confusion and misunderstanding of information and
the graphical symbols in this document are designed for such purpose.

3.1
graphical symbol
visually perceptible figure which is used for the purpose of transmitting information independent of
the medium of language
3.2
damage
physical harm that impairs the value, usefulness, or normal function of the vessel
3.3
incident
event that results in or may result in injury or ill-health to people, damage (3.2) or loss to property,
materials or the environment, or a loss of a business opportunity
Note 1 to entry: Unlike an accident, incident does not necessarily result in actual injury or damage.

4 T ype and use of graphical symbols
4.1 General
A computer-based incident response system shall employ, where applicable, the graphical symbols
described in this document. Where this document provides no appropriate symbol, another symbol
may be used. However, such symbol shall not be easily confused with the graphical symbols defined
in this document and shall follow the same generic principles applied in this document with regard to
colours, shapes and states.
4.2 Graphical symbols
4.2.1 The graphical symbols shall be of a suitable size and resolution to ensure they are clearly
understandable t
