As one of the necessary fire-fighting equipment in public places, fire extinguishers can prevent fires from happening at any time. Learning how to use a fire extinguisher is a necessary skill for everyone, but many friends still don't know how to use a fire extinguisher. It doesn't matter. I will introduce the steps and precautions for using a fire extinguisher. I hope it will be helpful to you.
1. Five steps to use a fire extinguisher
The five steps are looking, lifting, pulling, aiming, and pressing. First: refers to whether the fire extinguisher is still within the validity period, and seeing whether the pointer of the pressure gauge is in the green area; second: refers to lifting the fire extinguisher with both hands; third: pulls out the safety pin; fourth: aim the fire extinguisher at the root of the flame; fifth: presses Lower the handle, aim at the fire point, and press it all the way until the flame is extinguished.
2. Precautions for the use of fire extinguishers
1. Fire extinguishers in general public places are placed in corridors or passages, and there are eye-catching red signs. In daily life, whenever you go to unfamiliar public places, such as shopping malls, hotels, etc., you must first look at the route of the safe passage and the placement area of fire-fighting equipment. In case of a fire accident, you can put out the fire in time.
2. Regularly check the pressure of the fire extinguisher. If the pressure pointer points to the red area, it should be sent to a regular professional unit for maintenance or refilling; if it has been used, it should be sent to the maintenance unit for filling in time.
3. When it is officially used, handle it calmly. Shake the fire extinguisher first to loosen the internal dry powder, and then pull out the safety pin of the fire extinguisher. The person stands on the catchy mouth of the wind, aims at the root of the fire source, about 3 meters away from the fire source, and presses the button to put out the fire until the fire source is extinguished.
4. After the fire is extinguished, check whether there is any residual fire hidden; if there is, continue to spray a few times to prevent the re-ignition.
