1.1 本指南描述了控制已排放到环境中的有害物质扩散的方法。它针对的是那些受过足够危险品响应培训的应急响应人员。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 1.4 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本指南包含关于从容器中溢出的危险品的防护信息。如果能够控制材料，通常可以减少对环境的影响及其对响应者和公众造成的威胁。本指南中描述的技术是应急响应人员可用于减轻出院影响的技术之一。 在应用缓解技术之前，应进行初步危险评估。 4.2 应急响应人员可能包括警察、消防人员、政府泄漏响应人员、工业响应人员或泄漏响应承包商。为了应用本指南中描述的任何技术，建议进行适当的培训。见OSHA危险废物和应急响应标准（HAZWOPER）要求。

1.1 This guide describes methods to contain the spread of hazardous materials that have been discharged into the environment. It is directed toward those emergency response personnel who have had adequate hazardous material response training. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 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. 1.4 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 This guide contains information regarding the containment of a hazardous material that has escaped from its container. If a material can be contained, the impact on the environment and the threat it poses to responders and the general public is usually reduced. The techniques described in this guide are among those that may be used by emergency responders to lessen the impact of a discharge. Initial hazard assessment should be performed before applying mitigation techniques. 4.2 Emergency responders might include police, fire service personnel, government spill response personnel, industrial response personnel, or spill response contractors. In order to apply any of the techniques described in this guide, appropriate training is recommended. See OSHA Hazardous Waste and Emergency Response Standard (HAZWOPER) requirements.
