Many products have an expiration date, and anti-solvent aqueous film-forming foam fire extinguishing agents are no exception. Usually when purchasing, there will be a product manual with a clear description of the product expiration date. Everyone must first confirm whether their anti-solvent aqueous film-forming foam fire extinguishing agent has reached the expiration date. So, if the anti-solvent aqueous film-forming foam fire extinguishing agent reaches the expiration date, can it continue to be used? AFFF aqueous film-forming foam fire extinguishing agent, the state stipulates that the validity period is 8 years. If the storage environment is good, the validity period can be extended to 10-15 years. Can the anti-solvent aqueous film-forming foam fire extinguishing agent be used after the expiration date?
Fire-fighting foam liquid is different from ordinary things, because it shoulders a heavy responsibility, and everyone must be cautious about its use. Only in this way can we truly fulfill our responsibility to protect the people. Because the anti-solvent aqueous film-forming foam fire extinguishing agent is divided into several categories, the validity period of each category is different, and cannot be considered individually.
For example, G high-expansion foam fire extinguishing agent, the validity period specified by the state is 2 years; YE protein foam fire extinguishing agent, FP fluorine protein foam fire extinguishing agent, and S/AR alcohol-resistant foam fire extinguishing agent, the state specified validity period is 2 years, water-resistant Film-forming foam fire extinguishing agent is a multi-functional environmentally friendly foam fire extinguishing agent. It is composed of hydrocarbon surfactants, fluorocarbon surfactants, anti-drying agents, additives, polar film-forming agents, stabilizers, antifreeze, and anticorrosion. It is formulated with foaming agent, etc. According to the mixing ratio after mixing with water volume, it is divided into 3% AFFF/AR (foam fire extinguishing agent 3: water 97) and 6% AFFF/AR (foam fire extinguishing agent 6: water 94). The shelf life is eight years, of which the anti-solvent component is valid for two years, and after two years it can only be used as an aqueous film-forming fire extinguishing agent. But if the storage environment is good, the validity period can be extended to 3 years;
Because the solvent-resistant aqueous film-forming foam fire extinguishing agent is more concerned about the storage conditions, we cannot ensure that it has quietly undergone qualitative changes during the storage process, so we can find a special department for testing. It's more reliable.
