电动比例阀者在编制检查项目内容表时，要按有关规范要求对消防组织管理；油品的储存、外输管理、罐区的电器管理、火源控制、消防设施及器材管理等六个方面进行编制。
要充分估计和考察到那些内容忽略及较为隐蔽的问题，有针对性地写进检查表里。
按检查项目逐项仔细检查，才能发现问题、查出隐患。
防火安全检查切忌跑马观花式的快速巡回检查。
二是在整改上下功夫。
俗话说“旁观者清，当局者迷”，作为公安消防监督部门的人员，虽说对油库的防火安全管理实施严格的监督是责无旁贷的，但同时应充分运用专业知识和丰富的实践经验，将防火安全检查时发现的问题及隐患如实反馈给油库泵站的领导，协助制订整改措施，跟踪落实改进情况。
避免防火安全检查流于形式。
4、加强防火安全管理档案资料的建立长期以来，有些部门存在着不重视防火安全档案管理的问题。
上至油库泵站管理部门，下至基层单位，对防火安全检查的资料都不能完整地保存下来或很好地分类归档。
不利于总结经验教训，也不利于查寻和维修工作的顺利进行。
解决这一问题的对策：一是企业一定要把防火安全管理的档案资料纳入安全质量管理体系，明确管理职责，依据安全质量管理体系HSE的规范要求进行细化规范管理。
二是分类整理各种资料，及时归档，妥善保管，便于查阅。
