中国铝业中州分公司氧化铝厂(简称中州氧化铝厂)始建于1987年,是国家“七五”计划建设项目,设计产能年产20万t。中州氧化铝厂采用烧结法生产氧化铝,具有生产流程长、设备多、工艺复杂、连续作业等特点。中州氧化铝厂有大型设备200余套(台),泵类设备上千台,还有大量槽罐类、起重类和皮带输送等设备,清理检修(简称“清检”)工作繁重。而清检工作常面临着高空、高温、寒冷、狭窄、潮湿等相对恶劣的作业环境,人员相对集中,参与工种多,使用工具多,作业地点活,是生产安全事故易发人群、多发岗位。针对这一 Aluminum Corporation of China Zhongzhou Branch alumina plant (referred to as Zhongzhou alumina plant) was founded in 1987, is the national “75 ” project construction, design capacity with an annual output of 200,000 t. Zhongzhou alumina plant sintering production of alumina, with a long production process, equipment, complex technology, continuous operation and so on. Zhongzhou alumina plant has more than 200 sets of large equipment (Taiwan), pumping equipment thousands, as well as a large number of tanks, lifting and belt conveyor and other equipment, cleaning and maintenance (referred to as . The cleansing work is often faced with relatively harsh operating environments such as high altitude, high temperature, coldness, narrowness and humidity. The relatively concentrated personnel are involved in many types of work, many tools are used, and the worksite is live. It is a production-prone accident-prone group of people with multiple accidents. For this one
