How to write the ending of the fire extinguisher transformation composition?

Fire safety is more important than Mount Tai. I learned some fire fighting knowledge during the summer vacation. I often see fire scenes from TV and newspapers. It's really terrible and shocking! Fire is a symbol of human civilization. In modern society, people can't live without firing for a day. If there were no fire, what would human beings do? Without fire, human beings can only eat raw things. Since we have a fire, we can eat cooked food, which makes us very happy. Therefore, the appearance of fire has brought great changes to human society, making us bright in the dark and warm in the cold winter. But at that time, we didn't know the danger of fire. As the saying goes, "fire and water are ruthless." If we use fire improperly, it will burn our property at any time, hurt our lives and bring great disasters to mankind. But when we knew the danger of fire, we didn't stop using it, because we knew that fire was too important for us and we couldn't live without firing, so human beings knew that fire was still in use. But I always feel that the fire seems far away from me. Let me tell you how to prevent fire in winter, and pay attention to the following "seven taboos": First, avoid the fire caused by the failure of household appliances. When using electric stove, electric blanket, electric iron, etc. Fire caused by aging and frequent handling of wires must be avoided. Second, avoid throwing cigarette butts and causing fires. "A cigarette can destroy a building." Don't throw cigarette butts around, especially in places like kitchens where there are many flammable substances. Third, avoid setting off fireworks and firecrackers to cause fires. When setting off fireworks and firecrackers, we should master the correct discharge method, check and clean up the scene after discharge, and eliminate fire hazards. Fourth, avoid using fire to cause fire. It is forbidden to use flammable items such as gasoline, kerosene and alcohol for ignition in winter. Don't pile up flammable materials around the stove and don't bake clothes with heating equipment. Fifth, avoid burning garbage to cause fire. There may be flammable and explosive substances in garbage, such as liquefied gas residue, glass bottles, firecrackers, waste liquid lighters, etc. Once it burns, it may explode. Sixth, avoid the fire caused by gas leakage. Once gas leakage is found, the gas valve and stove switch should be closed immediately, and the doors and windows should be opened. At this time, do not switch any electrical appliances or use the indoor telephone. If you find a gas leak in your neighbor's house, you should immediately knock on the door to inform you. Don't use the doorbell. The seventh taboo is not equipped with fire fighting equipment. Every family should be equipped with a small fire extinguisher. , every member should master how to use it. While I warn people to prevent fire, we should also learn some common knowledge about fire control. Once you find a fire in your home, don't panic, keep calm and put it out in time and effectively. For example, if the liquefier catches fire due to air leakage, you can wet the towel or rag to cover the burner and quickly close the valve; When there is a fire in public places such as shopping malls, cinemas, supermarkets and auditoriums, everyone should keep a clear head and race against time to evacuate to the safe passage quickly and orderly. In case they are trapped in the fire, they should improvise and take appropriate measures to try to escape. I hope everyone can prevent fires in the future. Keep in mind the common sense of fire prevention and extinguishing!
