The working principle of domestic wet chemical fire extinguishers is to suppress the burning process of flames through chemical reactions. Its main component is an aqueous solution containing chemicals, usually including ammonia, ammonium phosphate, etc. When a fire extinguisher is used, the chemical reacts with the oxygen in the flame to form a chemical that inhibits the burning process of the flame.
Domestic wet chemical fire extinguishers are suitable for extinguishing various types of fires, including fires involving wood, paper, cloth, plastic and other combustible materials. Its use is relatively simple, just point the fire extinguisher at the fire source and spray it. Since it sprays a mist-like aqueous solution, it will not cause secondary pollution or damage to surrounding objects.
However, it should be noted that domestic wet chemical fire extinguishers are not suitable for electrical fires and oil fires. For electrical fires, using a wet chemical extinguisher may result in a shock hazard due to the conductive nature of the aqueous solution. For oil fires, due to the incompatibility between aqueous solutions and oil, the use of wet chemical fire extinguishers may cause the fire to expand.
Therefore, when choosing a fire extinguisher, you need to choose the corresponding fire extinguisher according to different fire types to ensure safe and effective fire extinguishing.
