Safety information for the content of piping systems and tanks — Part 1: Piping systems
This document specifies safety information for overground piping systems related to the content of the piping system and associated hazards for the purpose of accident prevention, reducing risks to health and providing information for use in case of an emergency. This document does not cover piping that is buried. Safety signing of the hazards in an area is not part of this document. This document can also be used for marine structures and ships.

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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the

Introduction
Continuous growth in mobility of labour has resulted in a need to standardize safety information
and form a coherent system for non-verbal exchange of information that consists of distinct elements
to identify hazards related to the content of piping systems and tanks. Every element of the safety
information system defined in this document communicates specific information. When combined on
a pipe marking, these elements inform the viewer, in a unique and simplified way, of potential hazards
so accidents can be prevented and an appropriate response to emergency situations can be efficiently
accomplished.
The use of this document is expected to reduce risk by providing a means of improved training and
education to reduce possible confusion for people working with and near piping systems in both normal
and emergency situations.
The use of a standardized safety information system does not replace proper work methods,
instructions or accident prevention training and measures. Education is an essential part of any system
that provides safety information.
Many different countries’ national pipe marking standards were reviewed during the development of
this document. Important design concepts contained in these standards were incorporated into this
document.
NOTE Some countries’ statutory regulations could differ in some respect from the requirements given in
this document.

content of a pipe. This safety information system shall be installed on site and near any place that might
require operation, maintenance or manipulation of a pipe’s contents.
This safety information system provides critical information that serves to assist in:
— the correct operation and use of the piping system;
— the safe maintenance of the piping system;
— conveying critical information to trained personnel in emergency situations.
