AFFF and AFFF Replacement

AFFF is a combination of fluorocarbons, surfactants, and solubilizers. The fluorochemical based surfactant reduces the surface tension of water allowing the foam to form an aqueous film on the surface of the…

What should be considered when switching from AFFF to Fluorine Free Foam?

The main difference between AFFF and Synthetic Fluorine Free Foam (SFFF) is the type of surfactants used in their formulation. AFFF contains fluorinated surfactants, which are  chemicals that are effective in extinguishing fires involving flammable liquids…

How Do You Put Out A Lithium-Ion Battery Fire?

Thermal Runaway of Lithium-Ion Batteries 

One of the main reasons why lithium-ion batteries can catch fire or fail is due to thermal runaway. This process can occur within the battery if it becomes too hot, and it causes a chain reaction that can ultimately lead to a fire. In addition, thermal runaway can happen if a battery is exposed to abused conditions such as high temperatures, physical abuse or if it is charged improperly.

During the thermal runaway of a battery, the chain reaction vaporizes the organic electrolyte and pressurizes the cell casing. If or when the case around the battery begins to fail, the flammable and toxic gases within the cell are released.
