常见有这样的场景：火初起时，人人拿起灭火器奋勇争先，满以为泰山压顶之势即可一举扑灭。可无奈，这边大火上房，那厢却按兵不动——灭火器毫无动静，只好眼睁睁看着烈焰腾空而起．究其因，灭火器旱巳过报废期矣！可悲，可叹。当你再购置灭火器时，别忘了，它也有它的“生老病死”的自然规律。 There is such a common scenario: When the fire started, everyone took the fire extinguisher and rushed to the front, believing that the pressure of Mount Tai could be extinguished. It was helpless. There was a fire on the room. The car was not moving. The fire extinguisher had no movement. The reason is that fire extinguishers have been scrapped for a long time! Sadly, sorry. When you buy a fire extinguisher again, don’t forget that it also has its natural law of “life and death.”
