Abstract

In order to prevent and control fire and explosion accidents in chemical industry parks, major hazard sources were identified with certain chemical industry park as an research example, and its radius of accident death, serious injury and minor injury were obtained by using assessment of major inflammable, explosive and toxic hazards through quantitative study. Then, vulnerability parts were analyzed by dividing accident scenarios into initial stage, development and expansion stage and recovery stage. Different evolution process of accidents under different response measures were discussed, and effective emergency solutions for disappearance of accident scenarios were analyzed. The results show that key measures to prevent and control major hazards and fire and explosion accident risks in chemical parks include detection and alarm, pressure relief and anti-reversal in initial stage, control and rescue in development and expansion stage, and transfer of major hazards within dominoes effect radius. © 2020 China Safety Science Journal.
