我国灭火器的型号是按照《消防产品型号编制方法》的规定编制的.它由类、组、特征代号及主要参数几部分组成.类、组、特征代号用大写汉语拼音字母表示；一般编在型号首位,是灭火器本身的代号.通常用“M”表示. 。灭火剂代号编在型号第二位：P——泡沫灭火剂,酸碱灭火剂；F——干粉灭火剂；T——二氧化碳灭火剂；Y——1211灭火剂；SQ——清水灭火剂. 形式号编在型号中的第三位,是各类灭火器结构特征的代号.目前我国灭火器的结构特征有手提式（包括手轮式）、推车式、鸭嘴式、舟车式、背负式五种,其中型号分别用S、T、Z、Z、B 。 MFZ、MFZL型手提贮压式干粉灭火器具有操作简单安全、灭火效率高、灭火迅速等特点.内装的干粉灭火剂具有电绝缘性能好、不易受潮变质、便于保管等优点,使用的驱动气体无毒、无味、喷射后对人体无伤害.灭火器瓶头阀上装有压力表,具有显示内部压力的作用,便于检查和维修。
