英文名称2：chlorohydricacid

分子式：HCl

分子量：36.46

2）成分、组成信息

有害成分含量CASNo.

盐酸36%7647-01-0

3）危险性概述

健康危害：接触其蒸气或烟雾，可引起急性中毒，出现眼结膜炎，鼻及口腔粘膜

有烧灼感，鼻衄、齿龈出血，气管炎等。误服可引起消化道灼伤、溃疡形成，有

可能引起胃穿孔、腹膜炎等。眼和皮肤接触可致灼伤。慢性影响：长期接触，

引起慢性鼻炎、慢性支气管炎、牙齿酸蚀症及皮肤损害。

环境危害：对环境有危害，对水体和土壤可造成污染。

燃爆危险：本品不燃，具强腐蚀性、强刺激性，可致人体灼伤。

4）急救措施

皮肤接触：立即脱去污染的衣着，用大量流动清水冲洗至少15分钟。就医。

眼睛接触：立即提起眼睑，用大量流动清水或生理盐水彻底冲洗至少15分钟。

就医。

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。如

呼吸停止，立即进行人工呼吸。就医。

食入：用水漱口，给饮牛奶或蛋清。就医。

5）消防措施

危险特性：能与一些活性金属粉末发生反应,放出氢气。遇氰化物能产生剧毒的

氰化氢气体。与碱发生中合反应，并放出大量的热。具有较强的腐蚀性。

有害燃烧产物：氯化氢。

灭火方法：用碱性物质如碳酸氢钠、碳酸钠、消石灰等中和。也可用大量水扑救。

6）泄漏应急处理

应急处理：迅速撤离泄漏污染区人员至安全区，并进行隔离，严格限制出入。建

议应急处理人员戴自给正压式呼吸器，穿防酸碱工作服。不要直接接触泄漏物。

尽可能切断泄漏源。小量泄漏：用砂土、干燥石灰或苏打灰混合。也可以用大量

水冲洗，洗水稀释后放入废水系统。大量泄漏：构筑围堤或挖坑收容。用泵转移

至槽车或专用收集器内，回收或运至废物处理场所处置。

7）操作处置与储存

操作注意事项：密闭操作，注意通风。操作尽可能机械化、自动化。操作人员必

须经过专门培训，严格遵守操作规程。建议操作人员佩戴自吸过滤式防毒面具（全

面罩），穿橡胶耐酸碱服，戴橡胶耐酸碱手套。远离易燃、可燃物。防止蒸气泄

漏到工作场所空气中。避免与碱类、胺类、碱金属接触。搬运时要轻装轻卸，防

止包装及容器损坏。配备泄漏应急处理设备。倒空的容器可能残留有害物。

储存注意事项：储存于阴凉、通风的库房。库温不超过30℃，相对湿度不超过

85％。保持容器密封。应与碱类、胺类、碱金属、易（可）燃物分开存放，切忌

混储。储区应备有泄漏应急处理设备和合适的收容材料。

8）接触控制、个体防护

中国MAC(mg/m3)：15

前苏联MAC(mg/m3)：未制定标准

TLVTN：OSHA5ppm,7.5[上限值]

TLVWN：ACGIH5ppm,7.5mg/m3

监测方法：硫氰酸汞比色法

工程控制：密闭操作，注意通风。尽可能机械化、自动化。提供安全淋浴和洗眼

设备。

呼吸系统防护：可能接触其烟雾时，佩戴自吸过滤式防毒面具（全面罩）或空气

呼吸器。紧急事态抢救或撤离时，建议佩戴氧气呼吸器。

眼睛防护：呼吸系统防护中已作防护。

身体防护：穿橡胶耐酸碱服。

手防护：戴橡胶耐酸碱手套。

其他防护：工作现场禁止吸烟、进食和饮水。工作完毕，淋浴更衣。单独存放被

毒物污染的衣服，洗后备用。保持良好的卫生习惯。
