密闭空间作业工伤事故百例分析研究

密闭空间作业是导致工伤事故不可忽视的重要原因之一。在洞穴、隧道、倾倒的建筑物、下水道和其他出入孔道、化粪池、罐釜维护检修等空间狭小、空气流通不畅的密闭空间场所工作，发生急性窒息性气体中毒或缺氧等事故的风险很高。为研究这类工伤事故原因及其影响因素，选择近年发生的122例典型事故案例，从调查统计事故发生的行业、岗位、原因、抢险和后果等入手，分析与工伤事故发生的关系，提出预防密闭空间作业伤亡的管理对策和有效工程技术控制措施的建议。

Analysis of 122 occupational accident cases in confined space

Working in confined space is one of the neglected important reasons that cause the occupational accident. When people working in the narrow, small space that the air doesn't smoothly circulate, such as cave, tunnel, dump building, sewer and other bore, septic tank and so on,the risk of taking place the impatient asphyxiation air or anoxia accident is very high. In order to study this occupational accident reason and its influence factors, we choose 122 typical occupational accident cases occurrence in recent years. By investigating the profession, post, reason and the accident result etc., the paper analyzes the relation of these factors and the occupational accident, and put forward some management countermeasures and suggestions of technique control measures to availably prevent the occupational accident in confined space.
