干粉灭火器使用时“摇”还是“不摇”?
来源:http://www.cx-fire.com/ 日期:2023-03-20
在一些网络“科普”里,会提到灭火器使用前要“摇一摇”。但灭火器使用的口诀是“提、拔、握、压”,并没有这个“摇”字。难道是我们遗漏了一项重要的步骤? 那必然是不可能的!下面
川消小编为您分析:
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:
现在干粉与灭火器技术非常成熟,瓶体内部压力是保持平衡的,干粉也是保持在“蓄势待发”的松散状态。
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".
合格的干粉灭火器中的干粉都要符合国家标准,且都通过了灭火器国家标准中的喷射性能、灭火性能等考核,只要压力指针在“绿区”范围内,就可以正常喷射。
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,市面上正规渠道售卖的合格干粉灭火器,使用前不需要“摇一摇”,记住“提、拔、握、压”的口诀就好。
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".
但如果是假冒伪劣产品,干粉质量不过关,出现结块现象,就不能保证了,或许“摇一摇”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.

灭火器的使用步骤:
Steps for using fire extinguishers:
一查
A check
检查灭火器压力表指示是否正常,筒体是否有锈蚀变形;
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
拔掉保险销;
Unplug the safety pin;
三压
Triple pressure
拉掉保险销后,一只手握住压把,另一只手抓好喷管喷嘴位置,将灭火器竖直放置;当用力按下压把时,干粉便会从喷管里面喷出;
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;
四喷
Four sprays
喷射时,要对准火焰根部,站在上风向离火焰根部距离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.cx-fire.com consulting service
