1.1本指南仅限于说明泡沫在水不混溶液体和沸点高于15的一些水反应性化合物中的应用 ° C用于控制蒸汽或灭火陆上溢出物或水中包含的溢出物。 1.2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。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 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和健康实践，并确定监管限制的适用性。 有关危险说明，请参阅第10节。 ====意义和用途====== 本指南旨在作为正确使用泡沫的一般指南。何时或是否使用泡沫的具体决定将取决于每种泄漏情况的情况和条件。 极性耐溶剂AFFF可通过中等膨胀泡沫喷嘴应用于某些水反应性化学品，以灭火并减少有毒蒸汽释放到环境中。

1.1 This guide restricts itself to addressing the application of foam to water immiscible liquid and some water reactive compounds with boiling points above 15 ° C for vapor control or fire suppression of land spill or contained spills on water. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 and health practices and determine the applicability of regulatory limitations prior to use. For hazard statements, see Section 10. ====== Significance And Use ====== This guide is intended as a general guide to the correct use of foams. Specific decisions on when or if foam should be used will depend on the circumstances and conditions of each spill situation. Polar solvent resistant AFFF can be applied to some water reactive chemicals with a medium expansion foam nozzle to extinguish a fire and to reduce toxic vapor release to the environment.
