2.对环境的影响:
一、健康危害

侵入途径：吸入、食入。 
健康危害：皮肤直接接触液态四氯化钛可引起不同程度的灼伤。其烟尘对呼吸道粘膜有强烈刺激作用。轻度中毒有喘息性支气管炎，严重者出现呼吸困难、呼吸脉搏加快、体温升高、咳嗽等，可发展成肺水肿。

二、毒理学资料及环境行为

毒性：属高毒类。 
急性毒性：LC50400mg/m3(大鼠吸入)

危险特性：受热或遇水分解放热，放出有毒的腐蚀性烟气。 
燃烧(分解)产物：氯化物、氧化钛。

疏散泄漏污染区人员至安全区，禁止无关人员进入污染区，建议应急处理人员戴正压自给式呼吸器，穿化学防护服。不要直接接触泄漏物，在确保安全情况下堵漏。喷水雾减慢挥发(或扩散)，但不要对泄漏物或泄漏点直接喷水。将地面洒上苏打灰，然后用大量水冲洗，经稀释的洗水放入废水系统。如果大量泄漏，最好不用水处理，在技术人员指导下清除。

二、防护措施

呼吸系统防护：可能接触其蒸气时，应该佩带防毒口罩。必要时佩带防毒面具。 
眼睛防护：戴化学安全防护眼镜。 
防护服：穿工作服(防腐材料制作)。 
手防护：戴橡皮手套。 
其它：工作后，淋浴更衣。单独存放被毒物污染的衣服，洗后再用。保持良好的卫生习惯。

三、急救措施

皮肤接触：尽快用软纸或棉花等擦去毒物，然后用水彻底冲洗。若有灼伤，就医治疗。 
眼睛接触：立即提起眼睑，用流动清水冲洗10分钟或用2%碳酸氢钠溶液冲洗。就医。 
吸入：迅速脱离现场至空气新鲜处。保持呼吸道通畅。呼吸困难时给输氧。给予2-4%碳酸氢钠溶液雾化吸入。就医。 
食入：患者清醒时立即漱口，给饮牛奶或蛋清。立即就医。

灭火方法：干粉、砂土。禁止用水。
