摘要

美国空军（USAF）规定了机库泡沫灭火系统的政策。2021 年 11 月，美国空军发布了《泡沫灭火系统日落政策》。美国国家防火协会的飞机库标准 NFPA 409 也具有类似功能。本文采用实际安装情况，分析了美国空军 "日落政策 "规定的机库防火方案与符合 NFPA 409 标准的安装情况的比较。应用零膨胀概率分布的泊松过程，对事件树的参考数据进行了评估和验证。分析表明，就风险分析而言，美国空军 "日落政策 "中规定的机库防火装置比符合 NFPA 409 标准的防火系统具有更好的性能。其次，安装符合 NFPA 409 要求的防火系统无法达到国际规范委员会性能规范 (ICCPC) 颁布的基本概率性能。验证结果还表明，与仅涉及火灾发生的情况相比，涉及消防泡沫意外喷射的情况发生的可能性要大得多。

A probabilistic analysis of non-military hangar fire protection systems

The United States Air Force (USAF) dictates policy for foam fire suppression systems in their hangars. In November 2021, the USAF issued a Sundown Policy for Foam Fire Suppression Systems. The National Fire Protection Association’s Standard on Aircraft Hangars, NFPA 409 serves a similar function. This article uses a real-world installation and analysis of the hangar fire protection scheme stipulated in the USAF Sundown Policy as compared to an installation in compliance with NFPA 409. Applying the Poisson process for a zero-inflated probability distribution, the data referenced for the event tree were evaluated and thereafter validated. The analysis shows that the installation of hangar fire protection stipulated in the USAF Sundown Policy achieves a better performance for the fire protection system than an installation in compliance with NFPA 409, insofar as the risk analysis is concerned. Second, the installation of a fire protection system that complies with the requirements of NFPA 409 fails to achieve the basic probabilistic performance promulgated by the International Code Council’s Performance Code (ICCPC). The validation also demonstrated that the scenario involving the accidental discharge of fire foam was significantly more likely to occur compared to that involving only fire occurrences.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
