Introduction: Fire extinguishers, also known as fire extinguishers, are one of the common portable fire protection facilities that are stored in public places or where fires may occur. Different types of fire extinguishers contain different ingredients and are designed for different fire alarms. Then, in the use process, we need to pay attention to what issues? 1. Some of the poisonous products of cyanide, such as ***, *** other cyanide, etc., in the case of foam acid can generate highly toxic gas***. Therefore, chemical foam cannot be extinguished and water and sand can be used to save.

2. Lithium, sodium, potassium, rubidium, strontium, magnesium, yttrium, etc. in water-fired articles because their metallic properties are very lively and they can capture oxygen from carbon dioxide and react as a chemical reaction. After this type of item caught fire, only general dry sand soil was used to save it, and it was also possible to save it with 1211. Flashable powder, **, **, aluminum, and nickel alloy hydrogenation catalysts in flammable solids cannot be extinguished with carbon dioxide.
3. In case of water-fired items fire, do not use water and water-containing foam to extinguish the fire because the water-burning items are chemically active and can displace the hydrogen in the water, generate combustible gases, and release heat. Such as ***, *** after water, can replace the water in the hydrogen, the heat generated by the hydrogen burning point. Others such as triethylaluminum, triisobutylaluminum, **, **, etc. have similar conditions. In addition, it is forbidden to stand in the downwind direction and not to wear gas masks such as oxygen respirator or air respirator, and to fight inorganic selenium compounds such as cyanide, phosphorus, and arsenic, and most organic fires.
