1.1 本指南概述了ASTM G04委员会关于富氧环境中材料的兼容性和敏感性的工作。对于那些提出“我使用氧气的风险是什么？”问题的人来说，这是一个起点。本指南介绍了在处理氧气时必须解决的独特问题。主要危险是可能引发火灾、爆炸或两者兼而有之。所有流体系统都需要设计考虑，例如足够的强度、耐腐蚀性、抗疲劳性和压力安全释放。除了这些设计考虑因素外，还必须考虑特定于氧气的点火机制- 浓缩系统。本指南概述了这些点火机制和降低风险的方法。 1.2 本指南还列出了氧气系统火灾的几种公认原因，并介绍了预防方法。列出并总结了有关氧气危害及其控制的信息来源。主要关注指南 第63页 , 第88页 实践 第93页 、和指南 第94页 。还引用了来自其他资源和文献的有用文献。 注1: 本指南是早期（1988年）G04委员会录像带附件的产物，标题为 氧气安全 科赫的一篇相关论文 2. 其重点是公认的绝热压缩点火源，这是氧气火灾的一个更重要但经常被忽视的原因。 本指南概括并更新了录像带和文件中的材料。 1.3 以国际单位制或英寸磅单位表示的数值应单独视为标准值。每个系统中所述的值不一定完全相等；因此，为了确保符合标准，每个系统应独立使用，两个系统的值不得合并。 1.4 本标准并不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建立适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体的预防性声明，请参阅章节 8. 和 11 . 注2: ASTM对与本指南中提及的任何项目相关的任何评估方法的有效性不持任何立场。明确建议本指南的用户自行决定任何此类评估方法和数据的有效性以及使用此类评估方法与数据的风险。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 本指南旨在介绍富氧系统的危害和风险。本指南解释了经常被忽视的常见危险。它概述了ASTM委员会G04和其他已知来源制定的标准和文件及其用途。它没有强调支持使用这些实践的标准测试方法。 表1 提供了ASTM G04标准关系的图形表示。 表2 提供了ASTM和其他组织发布的标准列表。 4.2 这里讨论的标准侧重于减少与氧气使用相关的危险。 一般来说，它们不直接适用于寻求材料与氧气的有意反应的工艺反应器，如燃烧器、露天看台或起泡器。其他ASTM委员会和产品（如CHETAH计划 5. )而其他外部群体则与这些更相关。 4.3 本指南不旨在作为规范来建立安全使用氧气的实践。本文所讨论的文件并非旨在包含安全设计和操作富氧系统所需的所有信息。对氧气危害的控制还没有简化为手册程序，使用氧气的策略也不简单。 相反，它们需要应用可靠的技术判断和经验。氧气使用者应获得合格技术人员的协助，以设计系统和操作规程，从而在其特定应用中安全使用氧气。

1.1 This guide covers an overview of the work of ASTM Committee G04 on Compatibility and Sensitivity of Materials in Oxygen-Enriched Atmospheres. It is a starting point for those asking the question: “What are the risks associated with my use of oxygen?” This guide is an introduction to the unique concerns that must be addressed in the handling of oxygen. The principal hazard is the prospect of ignition with resultant fire, explosion, or both. All fluid systems require design considerations, such as adequate strength, corrosion resistance, fatigue resistance, and pressure safety relief. In addition to these design considerations, one must also consider the ignition mechanisms that are specific to an oxygen-enriched system. This guide outlines these ignition mechanisms and the approach to reducing the risks. 1.2 This guide also lists several of the recognized causes of oxygen system fires and describes the methods available to prevent them. Sources of information about the oxygen hazard and its control are listed and summarized. The principal focus is on Guides G63 , G88 , Practice G93 , and Guide G94 . Useful documentation from other resources and literature is also cited. Note 1: This guide is an outgrowth of an earlier (1988) Committee G04 videotape adjunct entitled Oxygen Safety and a related paper by Koch 2 that focused on the recognized ignition source of adiabatic compression as one of the more significant but often overlooked causes of oxygen fires. This guide recapitulates and updates material in the videotape and paper. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4 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. For specific precautionary statements see Sections 8 and 11 . Note 2: ASTM takes no position respecting the validity of any evaluation methods asserted in connection with any item mentioned in this guide. Users of this guide are expressly advised that determination of the validity of any such evaluation methods and data and the risk of use of such evaluation methods and data are entirely their own responsibility. 1.5 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 ====== 4.1 The purpose of this guide is to introduce the hazards and risks associated with oxygen-enriched systems. This guide explains common hazards that often are overlooked. It provides an overview of the standards and documents produced by ASTM Committee G04 and other knowledgable sources as well as their uses. It does not highlight standard test methods that support the use of these practices. Table 1 provides a graphic representation of the relationship of ASTM G04 standards. Table 2 provides a list of standards published by ASTM and other organizations. 4.2 The standards discussed here focus on reducing the hazards associated with the use of oxygen. In general, they are not directly applicable to process reactors in which the deliberate reaction of materials with oxygen is sought, as in burners, bleachers, or bubblers. Other ASTM Committees and products (such as the CHETAH program 5 ) and other outside groups are more pertinent for these. 4.3 This guide is not intended as a specification to establish practices for the safe use of oxygen. The documents discussed here do not purport to contain all the information needed to design and operate an oxygen-enriched system safely. The control of oxygen hazards has not been reduced to handbook procedures, and the tactics for using oxygen are not simple. Rather, they require the application of sound technical judgment and experience. Oxygen users should obtain assistance from qualified technical personnel to design systems and operating practices for the safe use of oxygen in their specific applications.
