In order to reduce the probability of safety accidents in the process industry,the key causal factors of safety accidents in the process industry and targeted monitoring programmes for security management are identified with combination of systems thinking,correspondence analysis and case study methods.First-ly,systems thinking was applied to build a process industry accident causation system that includes four subsystems:human,equipment,environment and control method subsystems.Then,correlations between causal factors and accident levels,accident types,and industries in which the accidents occurred were deter-mined using correspondence analysis.Finally,combined with a major explosion and fire accident in a domes-tic petrochemical company,the reasonableness of the accident causation system and the corresponding anal-ysis results were verified.The results show that the monitoring process needs to focus on casual factors such as electric sparks,ambient temperature,raw material control,punching phenomenon,equipment clog-ging and combustible gases.Moreover,intelligent technological means such as video surveillance and sen-sors are used to implement monitoring and early warning of human,equipment and environmental subsys-tems.The monitoring strategy is informative for accident prevention and helps to promote the development of intelligent monitoring of production safety in the process industry.
