CAS号:
75-73-0
英文名称:
tetrafluoromethane;freon 14
危险性类别:
加压气体,特异性靶器官毒性-一次接触,类别3(麻醉效应)
危险性说明:
H280或H281:内装高压气体;遇热可能爆炸
或
内装冷冻气体;可能造成低温灼伤或损伤
H336:可引起昏睡或眩晕
燃烧与爆炸危险性:
不燃,无特殊燃爆特性。在高温火场中,容器内压增大,有开裂和爆炸的危险\r
中毒表现:
高浓度有麻醉作用。接触后可引起头痛、恶心和呕吐。接触液化气体可引起冻伤\r
急救措施:
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。呼吸、心跳停止,立即进行心肺复苏术。就医\r眼睛接触:不会通过该途径接触\r皮肤接触:如发生冻伤,用温水(38℃~42℃)复温,忌用热水或辐射热,不要揉搓\r食 入:不会通过该途径接触\r
灭火方法:
切断气源。消防人员须佩带防毒面具,穿全身消防服,在上风向灭火。喷水保持火场容器冷却,直至灭火结束。尽可能将容器从火场移至空旷处。本品不燃,根据着火原因选择适当灭火剂灭火\r
