疏散泄漏污染区人员至安全区，禁止无关人员进入污染区。应急处理人员戴自给式呼吸器，穿厂商特别推荐的化学防护服(完全隔离)。不要直接接触泄漏物。在确保安全情况下堵漏。用大量水冲洗，经稀释的洗液放入废水系统。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，应该佩戴防毒口罩。紧急事态抢救或撤离时，建议佩戴自给式呼吸器。
眼睛防护：戴化学安全防护眼镜。
身体防护：穿防腐工作服。
手防护：戴防化学品手套。
其它：工作现场严禁吸烟。工作后，淋浴更衣。实行就业前和定期的体检。保持良好的卫生习惯。

三、急救措施

皮肤接触：脱去污染的衣着，用肥皂水及清水彻底冲洗。若有灼伤，就医治疗。
眼睛接触：立即翻开上下眼睑，用流动清水冲洗15分钟。就医。
吸入：迅速脱离现场至空气新鲜处。呼吸困难时给输氧。呼吸停止时，立即进行人工呼吸。就医。
食入：误服者用水漱口，饮牛奶或蛋清，就医。

灭火方法：大火可用水，小火可用二氧化碳、干粉、砂土。
