马尾船政(连江)船舶与海洋工程装备特种船舶项目处于环境敏感区,工程各环节不存在重大危险源,风险评价等级为二级。工程最大可信事故为油漆房有机溶剂容器泄漏或破裂后造成火灾爆炸及火灾产生的次生污染物引起的环境事故。通过多烟团模式预测结果表明,事故发生后CO浓度对厂外人群危害较小。火灾事故发生时,项目建设方应在厂区内设置有效容积大于500m3的消防水池,用于储存含二甲苯消防废水。
Mawei Zhengzheng (Lianjiang) Ship and Offshore Engineering Equipment Special ship project is located in an environmentally sensitive area. There are no major hazards in all aspects of the project and the risk assessment level is Level 2. The largest credible accident in the project is an environmental accident caused by fire and explosion and secondary pollution caused by fire after the organic solvent container in the paint house leaks or ruptures. The result of multi-chimney model predicts that the CO concentration is less harmful to off-farm populations after the accident. When a fire accident occurs, the project constructor shall set up a fire-fighting water tank with an effective volume of more than 500m3 in the plant area for storing xylene-containing fire-fighting wastewater.
