\n\u003Cp>一、泄漏应急处理\u003C\u002Fp>\n\u003Cp>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，穿一般作业工作服。尽可能切断泄漏源，防止进入下水道、排洪沟等限制性空间。正在泄漏的1，3-二氯苯可用玻璃品或镀锌金属桶盛装，或筑防护堤。泄漏在水中的1，3-二氯苯，将沉于水底，并聚积在水底低洼处，可用泵抽出，放入玻璃品或金属桶内，泄漏的1，3-二氯苯要尽量避开水道和饮用水源；泄漏在土壤或地面上的1，3-二氯苯可用干 砂土混合，将污染的土壤全部装入可密封的袋中后，或倒到空旷地方掩埋，或作为废弃物进行焚烧；泄漏在空旷地方的1，3-二氯苯可就地掩埋。\u003C\u002Fp>\n\u003Cp>二、防护措施\u003C\u002Fp>\n\u003Cp>呼吸系统防护：可能接触其毒物时，必须佩戴自吸过滤式防毒面具(半面罩)。 眼睛防护：戴化学安全防护眼镜。 身体防护：穿防毒物渗透工作服。 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，沐浴更衣。单独存放被毒物污染的衣服。洗后备用。保持良好的卫生习惯。\u003C\u002Fp>\n\u003Cp>三、急救措施\u003C\u002Fp>\n\u003Cp>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。就医。 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。\u003C\u002Fp>\n\u003Cp>灭火方法：雾状水、泡沫、二氧化碳、砂土、干粉。\u003C\u002Fp>\n\n\u003C\u002Ftd>","2026-08-21T07:51:12.859463Z",false,[405,411,417,423,429,435],{"slug":406,"cid":407,"name":408,"nameZh":409,"cas":410},"785882709154074624","J-5441-4","2-(3-Methoxyphenyl)acetonitrile","3-甲氧基苯乙腈","19924-43-7",{"slug":412,"cid":413,"name":414,"nameZh":415,"cas":416},"785884633643356160","J-1319818-1","3-Phenylpyrrolidine","3-苯基吡咯烷","936-44-7",{"slug":418,"cid":419,"name":420,"nameZh":421,"cas":422},"785892517915660288","J-32786-6","2-Phenylpyrrolidine","2-苯基吡咯烷","1006-64-0",{"slug":424,"cid":425,"name":426,"nameZh":427,"cas":428},"785883082174500864","J-6949-8","2-Nitrobenzonitrile","2-硝基苯甲腈","612-24-8",{"slug":430,"cid":431,"name":432,"nameZh":433,"cas":434},"785891808310726656","J-31193-7","4-nitrostyrene","4-硝基苯乙烯","100-13-0",{"slug":436,"cid":437,"name":438,"nameZh":439,"cas":440},"785882704292876288","J-912262-2","4-Dimethylaminobenzaldehyde","对二甲氨基苯甲醛","100-10-7",1792625967419,"zh-CN",[]]
