The Potassium powder AEROSOL can be classified as an extinguishing agent that belongs in the category of the dry powders, commonly used in portable fire-extinguishers.
By definition, an aerosol is a system of solid or liquid particles that are suspended in a gaseous environment.
For example, smoke is the resulting aerosol produced by the combustion process. It’s formed by particles that measure a few microns in diameter (one millionth of a meter).
The extinguishing agents made from Potassium Salts dust (abbreviation “EA”) in an aerosol provides a unique method of extinguishing fires. Through the process of vaporization the substance is thinly dispersed in the environment and later due to the condensation of the same substance the fire is extinguished.
The extinguishing action of the aerosol is performed with the interruption of the auto-catalysis of the fire ( in other words, the interruption of the chain of reaction). Due to its unique chemical composition, the aerosol is capable of extinguishing fires even if its not sprayed directly into the fire; such a result is obtained through the saturization of the environment.
Besides, another characteristics of the aerosol is the slow decaying process in the environment (the substance tends to stratify) which allows it to maintains enough inertia to prevent relighting of the fire hotbeds.
