某化工厂的原料、中间产品有火灾、爆炸、中毒的危险性,生产的最终产品有Cl2和代号为CP的其他产品。生产工艺单元有:原料库房、氯气库房、产品CP库房、生产一车间和生产二车间,厂区周围有居民住宅和其他工厂。为此,工厂需编制事故应急预案。为避免重大事故发生,该厂决定编制应急救援预案。 厂长将该任务指派给安全科,安全科成立了以科长为组长,科员甲、乙、丙、丁为成员的五人的厂应急救援预案编制小组。编制小组找来了一个相同类型企业C的应急救援预案,编制人员将企业C应急救援预案中的企业名称、企业介绍、科室名称、人员名称及有关联系方式全部按本厂的实际情况进行了更换,按期向厂长提交了应急救援预案初稿。 厂长李某仔细认真审查了厂事故应急预案,认为:(1)事故应急预案中的“一旦事故发生,全厂员工应优先保护重要生产设备,救助他人”的应急原则,体现了保护企业财产,爱厂如家的奉献精神;(2)“应急救援领导小组组长为主管生产安全的副厂长王某”,体现了谁主管谁负责的原则;(3)“当发生重大氯气泄漏时由场外消防部门向周围居民发出警报”,体现了生产不扰民的原则;(4)“启动事故应急预案后,厂长甲应立即向当地安全生产监管部门、环境保护部门两个部门报警”的报警程序清晰;(5)应急救援物资和设备的评估合理。因此,厂长李某当场就让科长立即将事故应急预案打印发布。 厂长决定进行应急演习,并再次将任务交给科长。科长将演习地点设在氯气库房,厂应急救援指挥部设在氯气库房下风侧的平地上。演习过程为:第一步,指示人员A打开氯气库房中一个装有Cl2的钢瓶,使Cl2缓慢泄漏;第二步,工人B、C在氯气库房外面假装因Cl2中毒而晕倒;第三步,工人D、E发现有人晕倒,立即离开危险区,并向调度室报警;第四步,事故应急预案立即启动,所有应急人员到达指定位置和岗位;第五步,向110、119、120等外部应急救援部门报警;第六步,外部应急救援力量赶到现场,实施人员救护和抢险。 现场演练结束,领导进行了口头总结后,宣布演练结束。 根据以上场景,回答下列问题: 指出此次应急救援演练存在的主要不足之处,并写出应急演习总结报告。
