This International Standard prescribes safety signs for the purposes of accident prevention, fire protection, health hazard information and emergency evacuation.
The shape and colour required to be used for each sign, as prescribed by ISO 3864-1, is given together with the graphical symbols contained within each sign.
This International Standard is generally applicable to safety signs in workplaces and all locations and all sectors where safety-related questions may be posed. However, it is not applicable to the signalling used for guiding rail, road, river, maritime and air traffic and, in general, to those sectors subject to a regulation which may differ with regard to certain points of this International Standard and of ISO 3864-1.
This International Standard specifies the safety sign originals that may be scaled for reproduction and application purposes.
Supplementary text signs may be used in conjunction with these safety signs to improve comprehension.
