What are the disadvantages of s aerosol fire extinguishing equipment?
The metal salts and metal oxides in aerosol particles have certain electrical conductivity, which can cause short circuit of electrical equipment. After injection in the protection zone of the visibility is very low (less than about 1 meters), directly affect the evacuation (practice, the visibility of less than 3 meters, it is difficult to escape), so it should not be used in people often place. An aerosol fire extinguisher contains 40% of solid particles and therefore belongs to a non - clean fire extinguishing material.
Aerosol particles do not automatically evaporate into the atmosphere and are easily adhered to the surface of the equipment. Colloidal particles lead to light blockage, drum surface, disc cutting and connector wear.
Not easy to subside, because of the role of gravity field settlement in the surface or interior of protected objects, and some can cause equipment failure. Aerosol fire extinguishing agents are generally valid for four to six years, and are related to the preservation of the environment. The medicine must be renewed after the expiration date.
