BS ISO 3864-1:2011 pdf download – Graphical symbols — Safety colours and safety signs Part 1 : Design principles for safety signs and safety markings
This part of ISO 3864 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.
This part of ISO 3864 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.
NOTE Some countries’ statutory regulations might differ in some respect from those given in this part of ISO 3864.

ISO 17724:2003, Graphical symbols — Vocabulary 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 17724 and the following apply.
3.1 combination sign
sign that combines a safety sign and one or more associated supplementary signs on the same rectangular carrier
factor of distance
relationship between the height (h) of a sign and the observation distance (l), used to determine observation distances of signs z = l/h
[ISO 17724:2003, 28]
fire equipment sign
safety sign that indicates the location or identification of fire equipment
property of a graphical symbol which enables its elements to be perceived as the objects or shapes depicted
[ISO 9186-2:2008, 3.1]
mandatory action sign
safety sign that indicates that a specific course of action is to be taken
sign that combines two or more safety signs and associated supplementary signs on the same rectangular
safety sign that indicates that a specific behaviour is forbidden
safe condition sign
safety sign that indicates an evacuation route, the location of safety equipment or a safety facility, or a safety action
safe observation distance
distance a person can be from a safety sign while still able to identify the safety sign and have the opportunity to follow the message
NOTE Adapted from ISO 3864-2.
colour with special properties to which a safety meaning is attributed
marking which adopts the use of safety colours and safety contrast colours to convey a safety message or render an object or location conspicuous
sign which gives a general safety message, obtained by a combination of a colour and geometric shape and which, by the addition of a graphical symbol, gives a particular safety message
diameter of a circular geometric shape or height of a rectangular or triangular geometric shape
sign that is supportive of a safety sign and the main purpose of which is to provide additional clarification
capacity for seeing distinctly fine details that have a very small angular separation
[ISO 17724:2003, 82]
safety sign that indicates a specific source of potential harm
4 Purpose of safety colours and safety signs
4.1 The purpose of safety colours and safety signs is to draw attention rapidly to objects and situations affecting safety and health and to gain rapid understanding of a specific message.
4.2 Safety signs shall be used only for instructions which are related to the safety and health of people.
5 General meaning of geometric shapes and safety colours
The general meaning assigned to geometric shapes, safety colours and contrast colours is given in Tables 1 and 2.
