Abstract

Abstract: In order to study characteristics and causes of accidents in confined space,the statistics method was used to examine the data on the accidents happened in confined space during 2006-2015 in Beijing. Type, time, region and cause of the accidents were analyzed.The social network analysis method was used to identify the key factors influencing management of work safety in confined space. The result shows that main types of accidents are poisoning and suffocating, and the accidents occur commonly in summer. Regional distribution of accidents is related to the regional distribution of permanent resident population,that there is a positive correlation between the number of accident in a district and the population in it,that unsafe acts are the direct reason of the accidents, and no detection and ventilation before entering confined space and no wearing protective equipment are the main unsafe acts,that defects in management of work safety are the indirect cause of the accident,and that key factors affecting confined space safety management are leadership safety consciousness, safety input, and training in work safety.

Key words: confined space, operation accident, poisoning, suffocating, unsafe behavior
