健康危害：吸入、口服或经皮肤吸收对身体有害。具有刺激性。 二、毒理学资料及环境行为 急性毒性：LD50204mg\u002Fkg(小鼠静脉) 危险特性：其蒸气与空气可形成爆炸性混合物。遇明火、高热极易燃烧爆炸。与氧化剂能发生强烈反应。在空气中久置后能生成具有爆炸性的边氧化物。其蒸气比空气重，能在较低处扩散到相当远的地方，遇明火会引着回燃。若遇高热，容器内压增大，有开裂和爆炸的危险。 燃烧(分解)产物：一氧化碳、二氧化碳。 3.现场应急监测方法: 　 4.实验室监测方法: 色谱\u002F质谱法(EPA方法 1624) 气相色谱法(EPA方法 8015、EPA方法 5030) 高效液相色谱法，参照《分析化学手册》(第四分册，色谱分析)，化学工业出版社 5.环境标准: 美国 车间卫生标准 1050mg\u002Fm3(异丙醚) 6.应急处理处置方法: 一、泄漏应急处理 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：用活性炭或其它惰性材料吸收。也可以用大量水冲洗，洗水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。 二、防护措施 呼吸系统防护：空气中浓度超标时，佩戴过滤式防毒面具(半面罩)。 眼睛防护：高浓度环境中，戴化学安全防护眼镜。 身体防护：穿防静电工作服。 手防护：戴橡胶手套。 其它：工作现场禁止吸烟、进食和饮水。工作毕，淋浴更衣。注意个人清洁卫生。 三、急救措施 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。 眼睛接触：提起眼睑，用流动清水或生理盐水冲洗。就医。 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。 食入：饮足量温水，催吐，就医。 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：泡沫、干粉、二氧化碳、砂土。用水灭火无效。\u003C\u002Fp>\n\n\u003C\u002Ftd>","2026-08-21T07:51:12.859463Z",false,[424,430,436,442,448,454,460,466,472,478,484,490],{"slug":425,"cid":426,"name":427,"nameZh":428,"cas":429},"785893437093187584","J-1354068-6","Butyl
