Which fire extinguishing water should be used?
Water is the chemical compound of O2 and H with the formula H2O (H-O-H). The fire fighting function of water is to cool the fire. When sprayed on the fire it absorbs the heat of the burning area and the fire, reducing the temperature of the surrounding environment and the burning material. When the temperature drops below the combustion maintenance temperature, the burning will stop and the fire will be controlled. And here are some cases where water can be used to extinguish a fire:
+ Fires of materials such as wood, bamboo, straw, pressed core, fabric, ... spray water on the fire in the form of condensed water jet and dispersed water jet.
+ Fire of petroleum and its products, must have a boiling point higher than 80 degrees Celsius, in this case should spray water in the form of mist
+ Fire of electrical equipment has been disconnected, in this case water is sprayed in the form of dispersed solid jet or sprayed in the form of mist.
+ Burning oil and gas injection wells, using water in the form of condensed water jets

- Do not take fire extinguishing water for red-hot objects in a closed room because it may cause burns to the firefighter inside. Because the steam generated has an extremely high temperature.
- Flammable substances are alkali metals, alkaline earth, H2SO4, using water can cause explosion because water reacting with these substances will release explosive H2 gas. Therefore, absolutely should not use water to extinguish fires of this type.
- For combustible materials with strong water absorption ability, when spraying water, its weight will increase, and the risk of completely collapsing the floor may occur.
- Fires with Ti and TiO2 when sprayed with water will cause a decomposition reaction to release H2 causing explosion: The process is as follows: H2O -> H2 + O2
- Absolutely do not use water to handle fires of electrical equipment if you are not sure that the power source has not been completely cut off. Because when spraying water, it can cause electric shock, endangering the firefighter or people around if there is too much water overflowing on the ground. Not only that, water also makes electrical equipment around the fire damaged after fighting the fire.
