Several types of fire that cannot be saved by water

When a fire occurs in an electrical appliance, it is first necessary to cut off the power supply. Never use water and foam to save water if you can't power it off because both water and foam can conduct electricity. Carbon dioxide, 1211, dry powder fire extinguisher or dry sand should be used to save, and keep distances of more than 2 meters from electrical equipment and wires.

Do not pour with water when the pan pan is on fire. Because the water encounters hot oil, it will form a "fry pan" and splash oil everywhere. The method of fighting is to quickly pour the cut cold vegetables into the pot along the side and the fire will automatically go out. Another method is to use a lid or a large piece of wet cloth that covers the pan to cover the burning pan so that the burning oil does not contact the air.

Do not pour water from fuel oil, fuel oil or paint stored in your home. Use foam, dry powder or fire extinguishers or sand or fire.

When the computer computer catches fire, it should be immediately unplugged, and use dry powder or carbon dioxide extinguisher to save. If you find it timely, you can also unplug the power supply and quickly cover the computer with a wet carpet or quilt, etc. Do not splash water to the fire computer. Because of a sudden drop in temperature, the computer can also explode.

Chemical dangerous goods in school laboratories always have a certain amount of sulfuric acid, nitric acid, hydrochloric acid, alkali metal potassium, sodium, lithium, flammable metal aluminum powder, magnesium powder and so on. These items can easily react or burn after they encounter water and must not be saved by water.
