Do not pour water on the fuel oil or paint stored in your home if it catches fire. Use foam, dry powder or 1211 fire extinguishing equipment or sand to fight the fire.
When the oil pot catches fire, never use water either. Because water meets hot oil, it will form a "fryer", causing oil fire to splash everywhere. The rescue method is to quickly pour the cut cold dishes into the pot along the side, and the fire will automatically go out. Another method is to use a pot cover or a large damp cloth that can cover the oil pan to cover the burning oil pot, so that the burning oil fire can not reach the air and suffocates.
A certain amount of sulfuric acid, nitric acid, hydrochloric acid, alkali metal potassium, sodium, lithium, flammable aluminum powder, magnesium powder, etc. are often stored in school laboratories. These items are prone to react or burn when exposed to water, and they must never be extinguished with water.
