1.1 本规程规定了控制金属去除环境中呼吸道危害的指南。 1.2 本规程不包括预防皮炎，这是本规程的主题 E2693 ，但它确实采用了类似的系统管理方法，其中有许多共同的控制元素。 1.3 本规程侧重于员工通过吸入金属去除液和相关的空气传播剂进行接触。 1.4 用于湿法加工操作（如切割、钻孔、铣削或研磨）的金属去除液是金属加工液的一个子集，用于去除金属以生产成品零件。本规程不适用于使用除金属去除液以外的金属加工液的其他操作（如冲压、轧制、锻造或铸造）。这些其他类型的金属加工液操作不包括在本文件中，因为有关健康影响的信息有限，包括流行病学研究和控制技术。 尽管如此，本文件中包含的一些暴露控制方法和指南可能有助于管理与其他类型金属加工液相关的呼吸道危害。 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====== 4.1 在工业金属去除环境中暴露于气溶胶会对呼吸道产生不良影响。 4.2 使用这种做法将减轻职业暴露和在金属去除环境中暴露于气溶胶的影响。 4.3 通过实施该实践，用户应能够通过有效使用金属去除液管理程序、适当的产品选择、适当的机床设计、适当的空气处理机制和微生物控制来减少呼吸道刺激和疾病的发生率和严重程度。

1.1 This practice sets forth guidelines to control respiratory hazards in the metal removal environment. 1.2 This practice does not include prevention of dermatitis, which is the subject of Practice E2693 , but it does adopt a similar systems management approach with many control elements in common. 1.3 This practice focuses on employee exposure via inhalation of metal removal fluids and associated airborne agents. 1.4 Metal removal fluids used for wet machining operations (such as cutting, drilling, milling, or grinding) that remove metal to produce the finished part are a subset of metalworking fluids. This practice does not apply to other operations (such as stamping, rolling, forging, or casting) that use metalworking fluids other than metal removal fluids. These other types of metalworking fluid operations are not included in this document because of limited information on health effects, including epidemiology studies, and on control technologies. Nonetheless, some of the exposure control approaches and guidance contained in this document may be useful for managing respiratory hazards associated with other types of metalworking fluids. 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 ====== 4.1 Exposure to aerosols in the industrial metal removal environment has been associated with adverse respiratory effects. 4.2 Use of this practice will mitigate occupational exposure and effects of exposure to aerosols in the metal removal environment. 4.3 Through implementation of this practice, users should be able to reduce instances and severity of respiratory irritation and disease through the effective use of a metal removal fluid management program, appropriate product selection, appropriate machine tool design, proper air handling mechanisms, and control of microorganisms.
