How to put out the fire of alcohol

This period belongs to the high incidence period in novel coronavirus. Everyone must pay attention to personal hygiene, and at the same time wash their hands and disinfect frequently. Novel coronavirus can be disinfected with alcohol, so we must pay attention to safety when using alcohol for disinfection. So, if alcohol catches fire, how to put it out? Why not use water to put out the fire? Let's have a look!

Why can't alcohol use water when it is on fire?

Because alcohol is lighter than water, the burning flame will float on the water. In other words, water can't cut off oxygen, so it can't put out the fire. Besides, water and alcohol are both flowing liquids, which can easily expand the fire.

During the outbreak of novel coronavirus, disinfection with 75% or more alcohol can prevent virus infection. However, when using, be sure to stay away from open flames.

At the same time, foam extinguisher should not be used when alcohol is on fire. Because the foam is in contact with alcohol, alcohol will destroy the foam and will not form a foam layer isolated from oxygen on the surface of liquor, so it can not play a role in fire fighting.

Therefore, alcohol fire can only be put out with anti-soluble foam extinguisher, such as dry powder fire extinguisher or fine sand. In addition, you can also use wet rags, wet sacks, wet quilts, etc.

During my stay in novel coronavirus, it is necessary to disinfect with alcohol. But at the same time, we should also pay attention to personal safety and try to stay away from the kitchen and lighters.
