干粉滅火器使用時“搖”還是“不搖”？

在一些網絡“科普”里，會提到滅火器使用前要“搖一搖”。但滅火器使用的口訣是“提、拔、握、壓”，并沒有這個“搖”字。難道是我們遺漏了一項重要的步驟？ 那必然是不可能的！下面
川消小編為您分析：
In some online "science popularization", it is mentioned that fire extinguishers should be "shaken" before use. However, the pithy formula for using fire extinguishers is "lifting, pulling, grasping, and pressing", without the word "shaking". Are we missing an important step? That must be impossible! The following is an analysis by Sichuan Xiaobian:
現在干粉與滅火器技術非常成熟，瓶體內部壓力是保持平衡的，干粉也是保持在“蓄勢待發”的松散狀態。
Nowadays, the technology of dry powder and fire extinguisher is very mature, and the pressure inside the bottle is kept balanced, and the dry powder is also kept in a loose state of "ready to go".
合格的干粉滅火器中的干粉都要符合標準，且都通過了滅火器標準中的噴射性能、滅火性能等考核，只要壓力指針在“綠區”范圍內，就可以正常噴射。
The dry powder in qualified dry powder fire extinguishers must comply with national standards, and have passed the assessment of spray performance and fire extinguishing performance in the national standards for fire extinguishers. As long as the pressure pointer is within the "green zone" range, it can be sprayed normally.
所以，市面上正規渠道售賣的合格干粉滅火器，使用前不需要“搖一搖”，記住“提、拔、握、壓”的口訣就好。
Therefore, qualified dry powder fire extinguishers sold through regular channels on the market do not need to be "shaken" before use. Just remember the pithy formula of "lifting, pulling, grasping, and pressing".
但如果是假冒偽劣產品，干粉質量不過關，出現結塊現象，就不能保證了，或許“搖一搖”也拯救不了它的“病入膏肓”。
However, if it is a fake or shoddy product, the quality of dry powder is not up to standard, and there is caking phenomenon, it cannot be guaranteed. Perhaps "shaking" can not save its "terminally ill" condition.
滅火器的使用步驟：
Steps for using fire extinguishers:
一查
A check
檢查滅火器壓力表指示是否正常，筒體是否有銹蝕變形；
Check whether the indication of the pressure gauge of the fire extinguisher is normal and whether the cylinder is corroded or deformed;
二拔
Double extraction
拔掉保險銷；
Unplug the safety pin;
三壓
Triple pressure
拉掉保險銷后，一只手握住壓把，另一只手抓好噴管噴嘴位置，將滅火器豎直放置；當用力按下壓把時，干粉便會從噴管里面噴出；
After pulling off the safety pin, hold the pressure handle with one hand, grasp the position of the nozzle of the spray pipe with the other hand, and place the fire extinguisher vertically; When the pressure handle is pressed hard, dry powder will spray out from the nozzle;
四噴
Four sprays
噴射時，要對準火焰根部，站在上風向離火焰根部距離2-3米。
When spraying, aim at the flame root and stand 2-3 meters away from the flame root in the upwind direction.
I would like to remind you that it is necessary to purchase qualified fire protection products from regular channels in order to protect our lives and property at critical moments. For more relevant content, please visit our website http://www.xintli.net consulting service
