2.对环境的影响:
一、健康危害
侵入途径:吸入、食入、经皮吸收。
健康危害:对呼吸道有强烈的刺激性,吸入后引起咳嗽、呼吸困难、胸痛、肺水肿、昏迷。对眼和皮肤有强烈刺激性甚至引起灼伤。口服刺激和腐蚀消化道。
二、毒理学资料及环境行为
急性毒性:LD50500mg/kg(大鼠经口);850mg/kg(兔经皮);LC50800mg/m3 2小时(小鼠吸入)
危险特性:其蒸气与空气形成爆炸性混合物,遇明火、高热能引起燃烧爆炸。与氧化剂能发生强烈反应。其蒸气比空气重,能在较低处扩散到相当远的地方,遇火源引着回燃。若遇高热,容器内压增大,有开裂和爆炸的危险。有腐蚀性。

6.应急处理处置方法:
一、泄漏应急处理
疏散泄漏污染区人员至安全区,禁止无关人员进入污染区,切断火源。建议应急处理人员戴自给式呼吸器,穿一般消防防护服。不要直接接触泄漏物。在确保安全情况下堵漏。喷水雾会减少蒸发,但不能降低泄漏物在受限制空间内的易燃性。用沙土或其它不燃性吸附剂混合吸收,然后收集运至废物处理场所处置。也可以用大量水冲洗,经稀释的洗水放入废水系统。如大量泄漏,利用围堤收容,然后收集、转移、回收或无害处理后废弃。
二、防护措施
呼吸系统防护:可能接触其蒸气时,佩带防毒面具。紧急事态抢救或逃生时,佩带自给式呼吸器。
眼睛防护:戴化学安全防护眼镜。
身体防护:穿相应的工作服。尽可能减少直接接触。
手防护:戴防化学品手套。
其它:工作现场严禁吸烟、进食和饮水。工作后,淋浴更衣。进行就业前和定期的体检。
三、急救措施
皮肤接触:脱去污染的衣着,立即用流动清水冲洗至少15分钟。若有灼伤,就医治疗。
眼睛接触:立即提起眼睑,用流动清水或生理盐水冲洗至少15分钟。就医。
吸入:脱离现场至空气新鲜处。保持呼吸道通畅。必要时进行人工呼吸。就医。
食入:误服者给饮大量温水,催吐,就医。
灭火方法:泡沫、干粉、二氧化碳、砂土。用水灭火无效。
