大多数的人都知道有车载灭火器，但真正了解灭火器的的车主却是不多。车载灭火器必须要配置吗？是不是有保质期？？这些问题一直是车主不了解的知识。这也就造成了很多私家车在验车时被检查出来未配置灭火器，下面一起看看车载灭火器的作用。车内不配置灭火器据了解，很多车主在验车时多是临时借个灭火器过关，平时车内都没有灭火器，车内为什么不配备灭火器呢？一些车主认为，自燃往往与“老龄车”疏于保养以及车辆私自改造线路有关，自己购买的是新车，又勤于保养，根本不会发生自燃。还有一些车主认为，车辆发生自燃的几率很小，即使配备了灭火器，也未必管用，还不如购买“自燃险”。不止灭火器有保质期在给车配灭火器的车主中，有一半人表示，并不清楚灭火器有保质期。？据消防支队相关人士介绍，车载灭火器多为干粉灭火器，是以液态二氧化碳或氮气做动力，驱使干粉灭火剂喷出进行灭火，它的保质期为一年。车主每隔一年，就应该检查一下灭火器内气体是否泄漏，干粉是否结块，以此对灭火器进行充气或者换干粉，否则过了期的灭火器很可能喷不出来干粉，或者喷射的时间大大缩短，直接影响到正常使用。使用车载灭火器存在三误区扑明火灭火器只能用于灭初级火灾，要想起效必须掌握时机，这就意味着车主在发现汽车有异味冒烟时，应当即使用灭火器去扑救，否则见到明火后再去救，即使使用体积再大的灭火器也成了“杯水车薪”。救火重在掌握时机，而非取决于灭火器本身的大小校。灭火头车主在使用灭火器时，不能随便往火焰表面喷，而是应该对准火焰的根部，并确认火焰全部被扑灭后，才能将灭火器移开。捂车盖针对有人认为打开引擎盖，会让空气进入，让火烧得更旺，金巍表示，即使不打开引擎盖，空气也是相通的，遇火后打开引擎盖，第一时间找准着火点很重要。据了解，大部分的车主都不知道如何使用车载灭火器，只有极个别私家车主曾参加消防培训，亲手使用过灭火器。我卖我车网小编建议车主们了解一下车载灭火器的使用方法，并定期检查车载灭火器的保质期。
你好,我们是专业从事灭火器销售的,灭火器指针到红色是没有气压了,意思就是冲不出来干粉了,就算你想体验一下拔掉保险也冲不出来的,你可以到石桥铺交易城去找灭火器销售的地方,叫他给你维修一下,意思就是重新换粉,充压,要不然可以换一个新的,也就20-30元(车载灭火器1公斤的）。
