ISO 3864-1:2011为工作场所和公共区域中用于事故预防、消防、健康危害信息和紧急疏散的安全标志和安全标志确立了安全标识颜色和设计原则。它还确定了在制定包含安全标志的标准时要应用的基本原则。 ISO 3864-1:2011适用于所有需要解决人员安全问题的场所。然而，它不适用于用于引导铁路、公路、河流、海上和空中交通的信号，一般而言，也不适用于受不同法规约束的部门。

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.
