Identification and use of fire extinguishers

As we all know, fire extinguishers are one of the effective fire extinguishing equipment for fighting early fires. But if the fire extinguisher is counterfeit, can it still play a role in extinguishing fire? In order to find out the truth, yesterday, the officers and soldiers of the municipal fire brigade and the personnel of relevant enterprises conducted fire extinguishing experiments on the spot, intuitively showing the fire extinguishing effect of real and fake fire extinguishers.

In the morning of the same day, the experimenters prepared in advance a qualified fire extinguisher produced by a regular manufacturer and a counterfeit fire extinguisher, as well as an iron basin with a diameter of about 90 centimeters. Subsequently, the experimenters began to inject diesel and gasoline into the iron basin. In order to prevent oil splashing to the body and harming the skin during the fire extinguishing process, the experimenters wore protective clothing.

The experimenters used torches to ignite the oil basin, and in an instant the oil basin burned fiercely. The experimenters first used counterfeit fire extinguishers to extinguish the fire. I saw that the fire extinguisher continued to spray for more than 10 seconds, and the fire was still raging. Subsequently, the experimenters used a regular qualified fire extinguisher to extinguish the fire, and in about 10 seconds, the raging fire was completely extinguished.
