气态氢和燃料电池车辆第一和第二响应者推荐做法

[中文适用范围]： 与传统汽油内燃机相比，电动和替代燃料车辆对第一响应者和第二响应者带来不同的危险。涉及事故的氢汽车 (H2V)，包括燃料电池汽车 (FCV)，可能会带来与燃料存储和高压系统相关的独特危险。与混合动力电动汽车和燃料电池汽车的高压系统相关的电气危险已在父文档@ SAE J2990 中得到解决。因此，本推荐做法参考 SAE J2990 解决电气问题，并补充 SAE J2990，以解决与氢动力汽车事故相关的潜在后果，并提出通用程序，以帮助保护紧急响应人员@拖车和/或恢复@存储@维修@和救援人员发生了事件。研究了行业设计标准和工具，并在适当的情况下@建议负责组织实施。目的 本 SAE 推荐做法 (RP) 为氢动力汽车 (H2V)@（包括燃料电池汽车 (FCV)）相关事故的第一响应者和第二响应者提供指导和教育。 RP 无意取代紧急响应指南 (ERG) 或供紧急事件现场参考。我们鼓励汽车 OEM 在制定车辆要求和 ERG 时参考此 RP 作为行业设计指南。 [外文原描述]： xEVs involved in incidents present unique hazards associated with the high voltage system (including the battery system). These hazards can be grouped into three categories: chemical, electrical, and thermal. The potential consequences can vary depending on the size, configuration, and specific battery chemistry. Other incidents may arise from secondary events such as garage fires and floods. These types of incidents are also considered in the recommended practice (RP). This RP aims to describe the potential consequences associated with hazards from xEVs and suggest common procedures to help protect emergency responders, tow and/or recovery, storage, repair, and salvage personnel after an incident has occurred with an electrified vehicle. Industry design StandardDetails and tools were studied and where appropriate, suggested for responsible organizations to implement.Lithium ion (Li-ion) batteries used for vehicle propulsion power are the assumed battery system of this RP. This chemistry is the prevailing technology associated with high voltage vehicle electrification today and the foreseeable future. The hazards associated with Li-ion battery chemistries are addressed in this RP. Other chemistries and alternative propulsion systems including hydrogen fuel cells are not considered in this version of SAE J2990. Recommendations for hazards associated with hydrogen vehicles can be found in SAE J2990/1.Cross Reference: FMVSS208,FMVSS305,ISO9186-1,J1142_201910,J1143_201910,J1715_201410,J1766_201401,J2069_201910,J2344_202010,J2464_202108,J2830_201606,J2929_201302,J2950_202006
