Portable dry powder fire extinguishers are generally used in libraries to put out fires, because they can put out fires without getting dust on books, which can greatly reduce the damage to books.
Dry powder fire extinguisher can effectively absorb the heat on the surface of burning objects and cool the surface of objects, thus quickly extinguishing the flame.
In addition, books should be taken away in advance to avoid the spread of fire in the library.
If computer, electronic equipment or electrical fire is involved, CO2 fire extinguisher should be used, which can reduce the temperature of induction flame in the form of compressed carbon dioxide gas, and the fire extinguishing effect is better.
In addition, pay attention to personal safety when putting out the fire to avoid being polluted by flames, toxic gases and smoke.
