本文件规定了在发生自然灾害（如海啸、洪水、泥石流、陡坡崩塌、滑坡、龙卷风、大规模火灾、活火山）时，用于创建自然灾害安全道路引导系统的标志和计划的设计和应用原则，以帮助人们疏散到安全区域或避难所。 本文件提供了符合ISO？7010的安全标志、符合ISO？7001的公共信息符号的选择和使用指南，以及疏散路线标志、避难场所标志和疏散计划标志的文本，用于与一个或多个特定自然灾害相关的信息。还提供了自然灾害安全通道引导系统标志组件的设计、位置、安装位置和维护指南。 本文件不适用于确定自然灾害安全方式指南的必要性。本文件假设，执行机构的风险评估或要求已确定需要此类自然灾害安全方式指导系统。 本文件不适用于导致本文件所述自然灾害的大风、雪崩、地震或飓风等特殊危险。 本文件适用于从建筑物外部到安全区域的自然灾害的安全道路指南。ISO？16069适用于建筑物内通往紧急出口的安全通道指南。

This document specifies the principles governing the design and application of signs and plans used to create a natural disaster safety way guidance system to help people evacuate to safe areas or places of refuge in case of natural disasters (e.g. tsunamis, floods, debris flows, steep slope failures, landslides, tornados, large-scale fires, active volcanoes). This document provides guidance on the selection and use of safety signs conforming to ISO？7010, public information symbols conforming to ISO？7001, and text on evacuation route signs, places of refuge signs and evacuation plan signs for information related to one or more particular natural disasters. Guidance on the design, location, mounting positions and maintenance of the sign components of a natural disaster safety way guidance system is also provided. This document does not apply to the determination of the need for natural disaster safety way guidance. This document assumes that the risk assessment or requirements of an enforcing authority have established the need for such natural disaster safety way guidance systems. This document is not applicable to the particular hazards of high winds, snow avalanches, earthquakes or hurricanes, which cause the natural disasters covered in this document. This document is applicable to safety way guidance from natural disasters from the outside of buildings to safe areas. ISO？16069 is applicable to safety way guidance within a building to the emergency exit(s).
