Winter cold dry, with fire, electricity, gas generally increased, fire has entered a high incidence period, remind everyone timely installation of intelligent smoke sense alarm. After the occurrence of a fire, many people´s conventional thinking is to put out a fire with water. However, due to the different causes of the fire, blindly putting out a fire with water may backfire, turning water into fire "accelerant" and creating greater dangers. In the face of sudden fire, we should be calm and calm, analyze the type of fire and put out the fire. The following fires should not be put out with water.
I. Electrical fire
Once this kind of fire happens, never use water to put it out, because water will damage the electrical equipment, causing different degrees of economic loss, and water can conduct electricity, will cause the harm of electric shock. First of all, we must cut off the power supply. If the power cannot be guaranteed to be cut off, we can use dry powder fire extinguisher or dry sand to solve the problem. Moreover, we must keep a safe distance of more than 2 meters from the burning electric.
Second, the pan fire
Never use water to extinguish a fire in a frying pan. Because when water meets a hot pot, it forms a "fryer," causing the oil to splash around. Cover the burning oil with a lid or large wet cloth that covers the oil so that the burning oil does not come into contact with air.
Three, gasoline fire
Gasoline is less dense than water. If water is used to stop a gasoline fire, the gasoline floating on the water will continue to burn, and the gasoline will spread everywhere with the water, expanding the burning area. In case of gasoline fire, should immediately use foam, carbon dioxide and dry powder fire extinguishers and other fire extinguishing tools, strictly prohibit water extinguishing.
Four, paint fire
Paint contains a lot of organic solvents, lighter than water, spray paint on fire not only ineffective but will make the fire spread. Apply foam, dry powder, sand or 1211 fire extinguishers.
V. Special chemical fire
In the laboratories of some scientific research institutions or schools, there is often a certain amount of alkali metal sodium, potassium or sulfide, hydrochloric acid and other special chemicals stored in the water, some will have a violent reaction. For this kind of fire, can use dry sand, dry soil or dry powder to fight.
In a word, for the fire do not understand, do not act rashly, in the case of ensuring the safety of life, dial 119 waiting for rescue.
