迅速撤离泄漏污染区人员至安全区，并进行隔离，严格限制出入。切断火源。建议应急处理人员戴自给正压式呼吸器，穿消防防护服。尽可能切断泄漏源，防止进入下水道、排洪沟等限制性空间。小量泄漏：用砂土或其它不燃材料吸附或吸收。也可以用大量水冲洗，洗液稀释后放入废水系统。大量泄漏：构筑围堤或挖坑收容；用泡沫覆盖，降低蒸气灾害。用防爆泵转移至槽车或专用收集器内。回收或运至废物处理场所处置。 \n\u003Cbr \u002F> 二、防护措施 \n\u003Cbr \u002F> 呼吸系统防护：空气中浓度超标时，应该佩戴过滤式防毒面罩(半面罩)。\n\u003Cbr \u002F>眼睛防护：一般不需要特殊防护，高浓度接触时可戴化学安全防护眼镜。\n\u003Cbr \u002F>身体防护：穿防静电工作服。\n\u003Cbr \u002F>手防护：戴乳胶手套。\n\u003Cbr \u002F>其它：工作现场严禁吸烟。保持良好的卫生习惯。 \n\u003Cbr \u002F> 三、急救措施 \n\u003Cbr \u002F> 皮肤接触：脱去被污染的衣着，用肥皂水和清水彻底冲洗皮肤。\n\u003Cbr \u002F>眼睛接触：提起眼睑，用流动清水或生理盐水冲洗。就医。\n\u003Cbr \u002F>吸入：迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难，给输氧。如呼吸停止，立即  进行人工呼吸。就医。\n\u003Cbr \u002F>食入：洗胃。就医。 \n\u003Cbr \u002F> 灭火方法：尽可能将容器从火场移至空旷处。喷水保持火场容器冷却，直至灭火结束。处在火场中的容器若已变色或从安全泄压装置中产生声音，必须马上撤离。灭火剂：抗溶性泡沫、干粉、二氧化碳、砂土。\u003Cbr \u002F>\u003Cbr \u002F>\u003Cbr \u002F>\u003Cbr \u002F>\u003Cbr \u002F>\u003Cbr \u002F>\u003Cbr
