When putting out the fire, hold the bail in one hand and the bottom edge of the bucket in the other, turn the fire extinguisher upside down, aim the nozzle at the fire source, and shake it hard for a few times to put out the fire.
Second, portable carbon dioxide fire extinguisher

Five, clear water fire extinguisher
Clear water fire extinguisher is filled with clear water, and additives such as antifreeze are added. This kind of fire extinguisher puts out the fire by the principle of cooling and suffocation. Clear water can absorb sensible heat and latent heat, which has a significant cooling effect. When water is heated, it forms steam, which can reduce the oxygen solubility in the fuel area and so on. Clear water fire extinguishers are mainly used to extinguish Class A fires.
