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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

revised.
The main changes are as follows:
— the colour values for yellow in Table 2 have been modified;

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 that 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.
The national pipe marking standards of many different countries were reviewed during the development
of this document. Important design concepts contained in these standards were incorporated into this
document.
NOTE The statutory regulations of some countries can differ in some respect from the requirements given in this
document.
