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
The growth of international travel by ship and the variety of work on offshore installations have created
a need to provide people travelling and working on-board ships and other marine installations with
signs and associated systems that communicate consistent and effective safety information. This part of
ISO 24409 specifies a system of signs on ships and other marine installations that is generally consistent
with standardized systems of signs with which many will have gained familiarity in other applications.
As such, this part of ISO 24409 clarifies and supplements existing requirements set out in SOLAS
regulations II-2/13.3.2.5.1, II-2/13.1.3, II-2/13.7.1.1, II-2/13.7.2, III/8, III/9, III/11.5, III/20.10, and
ISO 17631.
This part of ISO 24409 is intended to improve the safety of passengers and crew on board ships and
marine installations by providing guidance on the signing of escape routes, including the use of arrows
to provide directional information, and in so doing to assist in orientation and in the description of
the planned escape process to passengers and crew. In addition, it provides guidance in signing of the
location and instructions for the use of fire-fighting equipment and life-saving equipment.
This part of ISO 24409 does not specify if and when escape route signs will be required. However, it
has been assumed in the drafting of this part of ISO 24409 that its execution will be entrusted to a
competent person familiar with the relevant regulatory requirements. This part of ISO 24409 is
also intended for use by regulatory authorities to assist in judging compliance with appropriate IMO
regulations and resolutions. It should be noted that the signing of escape routes comprises only a part of
the management of means of escape. Many other considerations have to be taken into account, including
the requirements of people with special needs, in order to establish a safe evacuation procedure.
This part of ISO 24409 reflects best practice; the illustrations reflect a system designed to provide the
optimum amount of information to clearly identify the location and direction of the means of escape from
any location within a ship, or offshore installation, to the assembly stations and appropriate survival
craft embarkation stations. However, as shown in examples, by the use of supplementary text, escape
route signing can also have a role to play in the management of a ship in non-emergency situations.

Part 3:
Code of practice
1 Scope
This part of ISO 24409 is intended to provide for the consistent use of shipboard safety and fire control
plan signs, guidance on their location and size, and for the use of appropriate graphical symbols and
supplementary text to furnish additional directional information. This part of ISO 24409 does not apply
to low-location lighting systems (or components of such systems) which are covered in ISO 15370.
