For the protection of water-soluble flammable liquids, which extinguisher type is required to be specifically listed on the nameplate?

For the protection of water-soluble flammable liquids, an AFFF (Aqueous Film-Forming Foam) extinguisher is specifically required to be listed on the nameplate. AFFF extinguishers are designed to combat fires involving flammable liquids by forming a foam blanket over the liquid surface. This foam helps suppress vapors and cools the burning material, making it particularly effective for water-soluble liquids that can mix with water and possibly create hazardous conditions.

AFFF agents are specifically formulated to deal with a variety of flammable liquids, including those that may react with water, thus providing an essential layer of safety and effectiveness in extinguishing these types of fires. The specific listing on the nameplate indicates that they have been tested and approved for these scenarios, ensuring compliance with NFPA standards.

Throughout the various options, other extinguisher types may lack the specific formulation or testing to handle the unique challenges presented by water-soluble flammable liquids, which underscores the importance of choosing AFFF extinguishers for this application.
