1.1 本指南涵盖了检查氧气系统火灾的程序和材料，以确定潜在原因并防止再次发生。 1.2 本指南并不全面。氧气火灾事件的分析不是一门科学，一些事件的确切原因尚未确定。 1.3 本指南中的程序和分析被发现有助于解释火灾事件，帮助确定潜在原因，并排除其他潜在原因。任何分析策略的包含或省略并不意味着该方法在任何实际事件研究中的适用性或不适用性。 注1: 尽管本指南适用于协助合格的技术人员分析事件，但每个事件都是独特的，必须作为一个独特的事件来处理。 因此，特定战术的选择和这些战术的应用顺序必须是研究事件的人有意识的决定。 注2: 该事件可能需要组建一个团队，以提供进行研究所需的专业知识和经验。分析事件的人员或团队中的至少一名成员应了解所研究的过程和设备安装。 1.4 警告- 在燃烧过程中，会产生气体、蒸汽、气溶胶、烟雾或其组合，这些气体可能存在，也可能对人有害。 小心 -应采取充分的预防措施来保护进行研究的人员。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 本指南帮助那些研究氧气系统事件的人选择直接原因假设，并避免基于过去被证明有错误的假设得出结论，无论这些假设多么可信。

1.1 This guide covers procedures and material for examining fires in oxygen systems for the purposes of identifying potential causes and preventing recurrence. 1.2 This guide is not comprehensive. The analysis of oxygen fire incidents is not a science, and definitive causes have not been established for some events. 1.3 The procedures and analyses in this guide have been found to be useful for interpreting fire events, for helping identify potential causes, and for excluding other potential causes. The inclusion or omission of any analytical strategy is not intended to suggest either applicability or inapplicability of that method in any actual incident study. Note 1: Although this guide has been found applicable for assisting qualified technical personnel to analyze incidents, each incident is unique and must be approached as a unique event. Therefore, the selection of specific tactics and the sequence of application of those tactics must be conscious decisions of those studying the event. Note 2: The incident may require the formation of a team to provide the necessary expertise and experience to conduct the study. The personnel analyzing an incident, or at least one member of the team, should know the process under study and the equipment installation. 1.4 Warning— During combustion, gases, vapors, aerosols, fumes, or combinations thereof, are evolved, which may be present and may be hazardous to people. Caution —Adequate precautions should be taken to protect those conducting a study. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This guide helps those studying oxygen system incidents to select a direct cause hypothesis and to avoid conclusions based on hypotheses, however plausible, that have proven faulty in the past.
