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

Continuous growth in mobility of labour has resulted in a need to standardize a safety information system 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 tanks, 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 tanks 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 or measures. Education is an essential part of any system that provides safety information.

1 Scope

This document specifies a safety information system for tanks made by combining several elements onto a single marking to communicate health and hazard safety information and information in case of an emergency for the purpose of accident prevention.

The organization's risk assessment will determine when and where this safety information system for tanks will be used. Possible applications include, but are not limited to:

• markings installed on or near fixed above-ground tanks;
• markings installed on portable tanks;
• markings installed on or near tanks used in production facilities, marine structures and ships;
• markings posted on or near interchangeable containers with fixed connection;
• markings installed on or near overground elements of underground tanks.

This document establishes additional principles to ISO 3864-1 for the purpose of establishing design principles for the display of safety information on tanks typically found in workplaces, industry and other facilities with tanks and containers. It covers safety information for tanks only. It is not intended for use on products.

This document does not cover tanks that are moved or transported. It does not apply to the labelling according to the United Nations' Globally harmonized system of classification and labelling of chemicals (GHS).^[5]

Safety signing of the hazards in an area is not part of this document.
