我们于1995年8月对三座高含硫污水罐进行了清罐作业。本文就高温下罐内作业环境中的劳动条件及卫生监护措施进行讨论。 容器内作业环境有害因素:H_2S浓度在1.0％～2.0％之间,平均1.2％,达到人体“电击样”致死浓度。高含硫污水中S与管道及容器中Fe反应生成硫化铁,沉积在罐壁及罐底,在常温下自然,生成大量SO_2。酸碱环境,对皮肤有刺激、腐蚀性。高温:夏季 In August 1995, we cleared three high-sulfur sewage tanks. This article discusses the working conditions in the tank operating environment and health monitoring measures at high temperatures. Hazardous factors in the container operating environment: H 2 S concentration of 1.0% to 2.0%, an average of 1.2%, reaching the body “shock-like” lethal concentration. S in high-sulfur sewage and pipe reactors and Fe in the reactor to generate iron sulfide, deposited in the tank wall and tank bottom, naturally at room temperature, generate a large amount of SO_2. Acid-base environment, the skin irritation, corrosive. High temperature: summer
