What is the standard for the number of fire extinguishers?

The maximum protection area of the fire protection level of the store warehouse unit is 75 square meters, and a fire extinguisher is equipped every 75 square meters at most.

When putting out a fire, the water vapor generated by water vaporization will occupy the space of the combustion zone, dilute the oxygen content around the combustion products, prevent fresh air from entering the combustion zone, and greatly reduce the oxygen concentration in the combustion zone, thus achieving the purpose of suffocating and extinguishing the fire.

When water is sprayed, the specific surface area of water droplets and fog droplets will be greatly increased, thus enhancing the heat exchange between water and fire, thus strengthening its cooling and suffocation effects.
