摘要
临港石化基地港口运输量大小直接影响到事故后果的严重程度。为有效控制港口危险品运输风险,提升港口安全水平,建立了基于风险的港口危险品安全运输量计算模型。以港口码头和船舶为出发点,选取池火灾、蒸气云爆炸、毒气泄漏3种典型事故,将事故预期死亡人数和事故发生概率相结合得到港口运输风险,并将人员平均风险值与可接受个人风险上限值比较,判断其合理性,根据每吨易燃、爆炸、有毒危险品对当班人员造成的平均风险值,推导得到最大安全运输量。计算实例表明,所建计算模型具有较好的可操作性和实用价值。
Port Freight volume of harbor petrochemical industry base has a direct impact on the severity of accident consequences. In order to effectively control the risk of dangerous goods transportation and improve the level of safeguard,a calculation model of port safety freight volume is proposed based on risk theory. Through analyzing the types of dangerous goods in port,three typical accidents of pool fire,explosion and toxic gas leakage are selected,and transportation risk is obtained by synthesizing the predicted death toll of accidents and probability. The rationality can be judged by means of comparing the individual average risk with the upper limit of acceptable individual risk. Finally the safety freight volume can be calculated according to individual average risk per ton flammable,explosive or toxic chemicals. The calculation example shows that the calculation model has strong operability and good practical value.
