AFFF or FFFP type extinguishers should only be used for protecting water-soluble flammable liquids if _____.

AFFF (Aqueous Film Forming Foam) and FFFP (Film-Forming Fluoroprotein) type extinguishers are specifically designed to combat fires involving flammable liquids, including water-soluble substances. However, they have specialized uses and characteristics that dictate their effectiveness in such scenarios. When utilizing these extinguishers for water-soluble flammable liquids, it's crucial that they are listed for this particular application on the nameplate.

The nameplate provides critical information about the extinguisher’s intended uses, including what kinds of fires it is rated to combat. If the extinguisher is not specifically listed for water-soluble flammable liquids, there is a risk that it may not effectively extinguish the fire or, in the worst case, could exacerbate the situation. Thus, the listing on the nameplate acts as a guideline to ensure that the extinguishing agent is appropriate for the type of fire being addressed.

Selecting the right type of extinguisher for specific fire classes is fundamental to fire safety, as using an inappropriate extinguisher can lead to severe consequences, including the potential for the fire to spread uncontrollably.
