AFFF, or Water Film-Forming Foam Fire Extinguishing Agent, is a common fire extinguishing agent that is especially used to extinguish fires with flammable liquids.
AFFF is designed to quickly form a thin film covering the surface of the liquid, thereby isolating the flame from contact with the air, extinguishing the flame and preventing the fire from burning again.
The main advantages of AFFF include:
AFFF is fast-acting: it quickly extinguishes the flame and effectively controls the spread of the fire.
Film formation: A thin film formed on the surface of the liquid effectively isolates the source of ignition, reduces oxygen**, and prevents the fire from re-ignition.
Wide range of application: suitable for a variety of flammable liquids, such as gasoline, grease, solvents, etc.
Good stability: This film maintains stability on the surface of the liquid, which can effectively prevent flame re-ignition for a long time.
While AFFF excels in liquid fires, there are some aspects to be aware of.
For example, for specific types of fires, such as metal fires or high-temperature grease fires, AFFF may not be as effective as other fire extinguishing agents specifically designed for such fires.
As a commonly used fire extinguishing agent, AFFF has a significant effect in liquid fire control, but in actual use, it is still necessary to select the appropriate fire extinguishing method and equipment according to the specific situation and fire type.
