Abstract

In order to objectively reflect the safety degree of a certain area, the accident death elasticity index and cloud model were applied to explore the spatial and temporal distribution and the causes of accidents in hazardous chemicals enterprises. Fatality elasticity was established on the basis of the existing statistical indicators as a new evaluation index. Cloud model was used to investigate the uniformity and stability of spatial and temporal distribution of accidents in Shandong province from 2000 to 2011. Finally, the direct cause of accidents was analyzed statistically based on the space-time scale. The results show that in the temporal dimensions, accident severity in April is the highest and its distribution shows great instability, the lowest in June, and the distribution of accident severity is the most stable in December, that in the spatial dimensions, the uneven and unstable distribution of accident severity is the largest in Southwest Shangdong, and the unevenness of accident severity in centralis small and stable, and that flammable and explosive chemicals are the main cause of accidents, and operational errors and neglect of safety and warning are the main unsafe act. © 2019 China Safety Science Journal
