Best place to use a fire extinguisher

The best location for the fire extinguisher to put out the fire is upwind or crosswind, because if a person inhales too much carbon dioxide, it will lead to death due to lack of oxygen. The upwind position is relative to the downwind position. For the two positions, which position the wind passes through first is the so-called upwind position. When using carbon dioxide, try not to let the wind blow the carbon dioxide towards people. Fire extinguishers are divided into dry powder fire extinguishers, foam fire extinguishers and carbon dioxide fire extinguishers. Dry powder fire extinguishers are more commonly used. When using, shake the bottle back and forth to loosen the dry powder inside, and then remove the lead seal and safety bolt. The posture is to hold the nozzle with the left hand and the pressure handle with the right hand, and then at a distance When the fire is about two meters away, press the handle with the right hand, and hold the nozzle with the left hand to spray dry powder back and forth. When using a foam fire extinguisher, pay attention to stand upwind and slightly close to the fire source. Its spray distance is about 2~3 meters, so start spraying from the place where the fire is larger, then move slowly, and hold the nozzle with your hand. Wooden handle, so as not to be frostbitten by the air-conditioning, after the fire is extinguished, the window should be opened in time to ventilate and ventilate the carbon dioxide in the air. Generally, there are two types of carbon dioxide fire extinguishers, switch type and guillotine type. When using, hold the wooden handle with one hand, press the switch with the other hand, and then lift the bottle up. In addition, the guillotine fire extinguisher cannot be closed after it is opened, and it is best to use it up at one time.
