The storage of foam fire extinguishing agent is very important, and the correct storage seriously affects the fire extinguishing performance of the foam. Therefore, we must strictly store it in accordance with the requirements of the product manual.
Pay attention to the shelf life of the foam extinguishing agent. When the storage conditions are good, the effective period of the protein foam solution and fluoroprotein foam solution can reach more than 5 years, the effective period of the aqueous film-forming foam solution can reach 10 years, and the effective period of the anti-solvent foam solution is only 1-2 years. The effective period of soluble aqueous film-forming foam fire extinguishing agent is 5 years;
Note the storage temperature of the foam. The storage temperature is too high or too low will affect the quality and shelf life of the solvent-resistant aqueous film-forming foam extinguishing agent.
Pay attention to keep the storage place ventilated and dry, avoid direct sunlight, and prevent impurities and other substances from mixing in;
Note that the storage container should be preserved. Aqueous film-forming and water-soluble foaming fire extinguishing agent, alcohol-resistant and water-soluble film-forming foaming fire extinguishing agent are relatively corrosive, and have special requirements for anticorrosive coatings, which should be taken seriously.
Anti-solvent aqueous film-forming foam fire extinguishing agent generally cannot be pre-mixed. Once pre-mixed with water, its effective period will be shortened to 5 years. However, with the development of new foam, the storage period has also changed greatly.
Therefore, the foam fire extinguishing agent must be properly stored and stored, so as to avoid affecting the performance of the fire extinguishing agent.
