Although the fire extinguisher has played a preventive role for everyone, many people have never used it. Once a fire occurs, they don’t know how to use it. This is a waste. Therefore, before a fire occurs, it must be used. Learn some things in advance. Here I suggest you to take a look at the fire extinguisher safety operation rules.
The foam fire extinguisher is suitable for extinguishing the first fire of oil and general substances. When in use, hold the lifting ring of the fire extinguisher with your hands and carry it to the fire site steadily and quickly. When extinguishing the fire, hold the lifting ring in one hand and the bottom edge of the barrel in the other, turn the fire extinguisher upside down, point the nozzle at the fire source, and shake it vigorously a few times to extinguish the fire.
Do not point the cover and bottom of the fire extinguisher to the human body to prevent the cover and bottom from popping out and injuring people. Do not spray with water at the same time, so as not to affect the fire extinguishing effect. When extinguishing electrical fires, try to cut off the power first to prevent personnel from getting an electric shock.
