Filling and loading stations , supply stations and pressure regulating stations for inflammable and explosive gas and liquid shall be set up in an appropriate location and shall conform to the requirements on prevention of fire and explosion 易燃易爆气体和液体的充装站、供应站、调压站，应当设置在合理的位置，符合防火防爆要求。
As in the process of operation , the compression of air is carried out under constant temperature , so there would not cause danger in the compression and pumping of inflammable and explosive gas , thus making them very popular 由于在工作过程中，该类泵对气体的压缩是在等温状态下进行的，因此在压送或抽吸易燃、易爆气体时，不易发生危险，所以其应用更加广泛。
Because the hydrogen has the special kind in quality , its density is small , the molecular weight is small , so the common stop valve can ' t satisfy it requests , and , the hydrogen belong to the combustible and explosive gas , once leak happened , will exist hidden trouble 摘要由于氢气性质特殊，其密度小，分子量小，所以普通截止阀不能满足它的使用要求，而且氢气属于易燃易爆气体，一旦发生?漏，会存在很大的隐患。
For existing factories and warehouses and specialized depots and wharves for production , storage , loading and unloading of inflammable and explosive dangerous goods , and filling and loading stations , supply stations and pressure regulating stations for inflammable and explosive gas and liquid , in case they do not conform to the regulations of this article , relevant units shall adopt measures to give a solution within a time limit 原有的生产、储存和装卸易燃易爆危险物品的工厂、仓库和专用车站、码头，易燃易爆气体和液体的充装站、供应站、调压站，不符合前款规定的，有关单位应当采取措施，限期加以解决。
