Study on Safety Capacity of Chemical Industrial Park in Operation Stage

It's important for the safety planning of the chemical industrial park to calculate the safety capacity of the park as chemical industrial parks developed fast in recent decades in our country. This paper defined the safety capacity of chemical industrial park and improved the calculation methods which had been presented. The safety capacity of chemical industrial park could be calculated by using the indictors of the safety capacity (individual risk, social risk and potential risk), in the basic information of the park, such as the production scale of enterprises in the park, layout and the population distribution and so on. The new method presented the concepts of hazardous chemicals equivalent to research the impact of the hazardous chemicals species to the safety capacity. The effect of population distribution will also be considered when calculating the safety capacity. Besides, the domino effect should be discussed to fix the safety capacity of the chemical industrial park when the park is at full load condition. Then, the real safety capacity of the park could be calculated. Finally, the analysis process of the appropriate safety capacity is illustrated with an application example in a certain chemical industrial park.
