Typical fire extinguishing systems found in commercial and industrial locations include sprinklers, carbon dioxide, clean agent, and dry/wet chemical agents. Another fire extinguishing technology available, but less common, is condensed aerosol. These systems take advantage of the well-established fire suppression capability of solid particulates, with potentially reduced collateral damage associated with traditional dry chemicals. However, there are some concerns in regard to collateral damage to computers and other sensitive electronic equipment.
History Of System
Potassium was first isolated by Davy in 1807 through the electrolysis of molten potassium hydroxide (KOH), from which the name potassium is derived . At roughly the same time (1807 – 1808) Gay-Lussac and Louis Jacques The nard obtained the element through the reduction of molten potassium carbonate with iron filings in an iron crucible.
How do Condensed Aerosol Systems Work?
The idea of the work of Fire Pro depends on the transformation of the solid material into the gaseous substance when exposed to high temperatures. The gas of the Aerosol comes out as a misty gas consisting of calcium carbonate, nitrogen, water vapor and carbon dioxide. The fog gas extinguishes the fire by breaking the chemical reaction chain of fire and completely.(See in PIC).
1. Easier installation - no piping, pressure cylinders, special supports or valves are required, thus reducing installation time and labor costs considerably. 2. Environment friendly and nontoxic. 3. Cost less if compared to other system. 4. Easy maintenance without the need for pressure testing, weighing, pressure/leak detection, filling, etc. 5. Self-activation temperature 300 •C.
1. Releases misty gas, which hinders the process of evacuation during the fire. 2. It is not recommended to be installed in populated areas (e.g patient areas - patient critical areas…..). 3. Shall not be used on deep-seated fires in Class A materials (i.e. paper, wood, cloth, rubber and many plastics). 4. Shall not be used on certain chemicals or mixtures of chemicals, such as cellulose nitrate and gunpowder, that are capable of rapid oxidation in the absence of air. 5. Find chemical reactive on metals such as lithium, sodium, potassium, magnesium, titanium, zirconium, uranium, and plutonium.
