ISO 18639系列标准规定了个人防护设备（PPE）的要求，该设备专门用于保护消防员在从事特定救援活动时免受伤害和/或生命损失。 ISO 18639系列提供了控制事故类型和/或特定危险最低测试方法制定的原则，包括消防员和其他救援人员穿戴的个人防护装备（PPE）的设计和性能要求，以减少参与救援活动时的伤害和/或生命损失。 为了帮助根据风险评估（见附录C）进行选择，包括不同防护类别的PPE类型（如适用）和性能水平。 ISO 18639-1:2018涵盖了道路交通事故（RTC）和城市搜索救援（USAR）救援活动中使用的PPE，但也可能包括其他救援活动，具体取决于风险评估。 ISO 18639-1:2018不包括用于高风险火灾暴露的PPE。 同样，本文件不包括防止化学和生物危害的PPE，但在从事救援活动时防止短期和意外接触的PPE除外。 ISO 18639-1:2018描述了ISO 18639系列的总体结构，包括每个小节，规定了PPE的设计和性能要求，包括标记要求和制造商说明。

ISO 18639 series of standards specify requirements of personal protective equipment (PPE) specifically designed to protect firefighters from injury and/or loss of life while engaged in specific rescue activities. ISO 18639 series provides the principles that govern the development of incident type and/or hazard specific minimum test methods including design and performance requirements for personal protective equipment (PPE) worn by firefighters and other rescue workers to reduce injury and/or the loss of life while engaged in rescue activities. To assist with selection based on a risk assessment (see Annex C), type of PPE, (if applicable) and performance levels, for different categories of protection are included. ISO 18639-1:2018 covers PPE for use in the rescue activities for road traffic crash (RTC) and urban search and rescue (USAR), but could also include other rescue activities depending on the risk assessment. ISO 18639-1:2018 does not include PPE for use in high risk fire exposures. Similarly, this document does not include PPE to protect against chemical and biological hazards, except against short term and accidental exposures whilst engaged in rescue activities. ISO 18639-1:2018 describes the general structure of the ISO 18639 series, including each subsection, sets design and performance requirements for PPE and includes requirements for marking and manufacturer's instructions.
