Safety Signs and Labels Safety Signs and Labels Standards delineate the proper design, classification, and implementation of safety signs and safety labels. The cross-industrial standardization of safety signs and labels is integral to the reduction of risks to health and safety. Safety signs and labels standards are a key part of ongoing efforts to promote safe practices throughout an exceptionally wide range of specific situations. Accident prevention, protection from health hazards, product safety identification, fire protection, and emergency evacuation make up only part of the more salient safety promotion principles being fostered. Safety Signs and Labels Standards serve to reduce safety risk throughout commercial, industrial, public, and residential areas by means of specifying internationally agreed upon optimal design principles for safety signs and labels, including the specification of colors, signal words, photometric properties, fixing methods and surfaces, proper illumination, graphical symbols, and much more.

ISO 3864-1:2011

Graphical symbols - Safety colours and safety signs - Part 1: Design principles for safety signs and safety markings

ISO 3864-1:2011 establishes the safety identification colours and design principles for safety signs and safety markings to be used in workplaces and in public areas for the purpose of accident prevention, fire protection, health hazard information and emergency evacuation. It also establishes the basic principles to be applied when developing standards containing safety signs. ISO 3864-1:2011 is applicable to all locations where safety issues related to people need to be addressed. However, it is not applicable to the signalling used for guiding rail, road, river, maritime and air traffic and, generally speaking, to those sectors subject to a regulation which may differ.

This standard is also available from: BS  /  DIN


ISO 3864-2:2016

Graphical symbols - Safety colours and safety signs - Part 2: Design principles for product safety labels

ISO 3864-2:2016 establishes additional principles to ISO 3864 1 for the design of safety labels for products, i.e. any items manufactured and offered for sale in the normal course of commerce, including but not limited to consumer products and industrial equipment. The purpose of a product safety label is to alert persons to a specific hazard and to identify how the hazard can be avoided. ISO 3864-2:2016 is applicable to all products in all industries where safety-related questions can be posed. However, it is not applicable to safety labels used - for chemicals, - for the transport of dangerous substances and preparations and - in those sectors subject to legal regulations which differ from certain provisions of this document. The design principles incorporated in this document are intended to be used by all ISO Technical Committees and anyone designing product safety labels in the development of product safety label standards for their industries or services.


ISO 3864-3:2012

Graphical symbols - Safety colours and safety signs - Part 3: Design principles for graphical symbols for use in safety signs

ISO 3864-3:2012 gives principles, criteria and guidance for the design of graphical symbols for use in safety signs as defined in ISO 3864 1, and for the safety sign element of product safety labels as defined in ISO 3864 2.

This standard is also available from: BS  /  DIN


ISO 3864-4:2011

Graphical symbols - Safety colours and safety signs - Part 4: Colorimetric and photometric properties of safety sign materials

ISO 3864-4:2011 establishes the colorimetric and photometric requirements and test methods for the colours of safety signs to be used in workplaces and public areas. It provides the colorimetric and photometric specifications for the named safety and contrast colours prescribed in ISO 3864-1. The physical requirements that safety signs have to meet are primarily related to daytime colour and normally lit environments. ISO 3864-4:2011 also includes the colorimetric requirements and test methods for safety signs and phosphorescent material which also operate in unlit environments. ISO 3864-4:2011 is applicable to all locations where safety issues related to people need to be addressed. However, it is not applicable to signalling used for guiding rail, road, river, maritime and air traffic and, generally speaking, to those sectors subject to a regulation that may differ. The colorimetric and photometric properties of retroreflective safety signs, retroreflective materials combined with fluorescent or phosphorescent materials, or luminous safety signs activated by a radioactive source are not specified in ISO 3864-4:2011.

This standard is also available from: BS

ISO 20712-1:2008

Water safety signs and beach safety flags - Part 1: Specifications for water safety signs used in workplaces and public areas

ISO 20712-1:2008 prescribes water safety signs intended for use in connection with the aquatic environment. It is intended for use by owners and operators of aquatic environments and by manufacturers of signs and equipment. However, it is not applicable to signalling used for maritime traffic. The shape and colour required to be used for safety signs, as prescribed by ISO 3864-1, are given together with the graphical symbols contained within each sign. The water safety sign originals meet the design criteria of ISO 3864-3. ISO 20712-1:2008 specifies the water safety sign originals that may be scaled for reproduction and application purposes. ISO 20712-1:2008 includes water safety signs which require that supplementary text signs be used in conjunction with these water safety signs to improve comprehension.


ISO 17398:2004

Safety colours and safety signs - Classification, performance and durability of safety signs

ISO 17398:2004 specifies requirements for a performance-related classification system for safety signs according to expected service environment, principal materials, photometric properties, means of illumination, fixing methods and surface. Performance criteria and test methods are specified in ISO 17398:2004 so that properties related to durability and expected service life can be characterized and specified at the time of the product's delivery to the purchaser. ISO 17398:2004 does not cover electrical power supplies, their components or electrically powered elements. It also does not cover properties of illuminating components, but the photometric properties for the particular types of safety signs are covered.
