Why is hot water more effective at extinguishing fires

Why is hot water more effective at extinguishing fires? Because hot water is sprayed on the burning objects, it not only has a cooling effect, but also the surroundings of the burning objects are quickly enveloped by clouds of steam, which reduces the surrounding oxygen.

Once the fire is deprived of oxygen, the fire will inevitably be controlled. These steam layers play a major role. The area is suffocated, so that the fire intensity changes from strong to weak, and finally achieves the effect of extinguishing fire and eliminating disasters.

In fire extinguishing practice, 1 liter of hot water is equivalent to 20 to 30 liters of cold water per second. If boiling water is used to extinguish the fire, five firefighters can complete the workload of dozens of firefighters, getting twice the result with half the effort.

Where conditions permit, hot water should be widely used to extinguish fires, but one thing must be paid great attention to, avoid using hot water Burn people.
