不要直接接触泄漏物，用清洁的铲子收集于干燥洁净有盖的容器中，以少量加入大量水中，调节至中性，再放入废水系统。
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，收集回收或无害处理后废弃。
Isolate area of leak , and fix warning signs around . Suggest that related personnels wear gas mark and wear chemical protective clothing avoiding direct contact with leakage , Pick up and place in a dry and clean container with cover, using a clean shovel. Add a lot of water into a little sodium hydroxide until it becomes neutral and then put it into waste water processing system ,or flush it with plenty of water and put the dilute solution into waste water processing system ,if severe leak occurs , collect and recycle or abandon after harmless processing三、防护措施Protection measurement呼吸系统防护：必要时佩带防毒口罩。
Respiratory protection ：Wear a respirator if necessary眼睛防护：戴化学安全防护眼镜。
Eye protection ：Use chemical safety goggles防护服：穿工作服(防腐材料制作)。
Body protection ：Wear impervious protective clothing, (made from corrosion resistance material)手防护：戴橡皮手套。
Hand protection: impermeable gloves其它：工作后，淋浴更衣。
注意个人清洁卫生。
