1.1本指南描述了控制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。 ====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控制信息。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。 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。

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. ====== 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. 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.
