氢氟酸(液体或蒸气)急性中毒后死亡原因多认为由于大量氢氟酸蒸气吸入并发肺水肿引起。经皮吸收发生全身中毒虽有报告,但未有致死者。故与呼吸道或消化道吸收比较,一般认为经皮肤吸收并不是引起氟中毒的重要机制。下面介绍一例因皮肤氢氟酸严重烧伤引起了急性系统性氟中毒而死亡。1979年5月20日下午5:45左右,一名炼油厂操作工在拔装置上的插销时,不慎被无水氢氟酸喷溅到面部。当时,他佩戴的防护用品有带护目镜的硬质帽子、氯丁橡胶制的长统靴、手套、茄克衫以及常规用的供氧式面罩。事发后10分钟,在控制室里发现了他,虽全身已淋湿,仍立即给他用水冲洗并使用氧化镁制剂,即送地区医院作进一步处理,时间为下午5∶55。6∶10到达急诊室,意识清楚,血压146/82,
Hydrofluoric acid (liquid or vapor) after acute poisoning and more due to the death of a large number of hydrofluoric acid vapor inhalation caused by pulmonary edema. Although percutaneous absorption of systemic poisoning have been reported, but not fatal. Therefore, compared with the respiratory tract or digestive tract absorption, it is generally believed that the absorption of the skin is not an important mechanism that causes fluorosis. Here is an example of a serious hydrofluoric acid skin burns caused by acute systemic fluorosis and death. At about 5:45 pm on May 20, 1979, a refinery operator accidentally was splashed on the face with anhydrous hydrofluoric acid while pulling the plug on the device. At the time, he was wearing protective gear with hard hat with goggles, neoprene boots, gloves, jackets and conventional oxygen masks. Ten minutes after the incident, he was found in the control room. Although his body was wet, he was immediately rinsed with water and made use of magnesia preparations, which he sent to the district hospital for further treatment at 5:55:10 PM Arrived at the emergency room, conscious, blood pressure 146/82,
