What color is AFFF concentrate?

AFFF concentrate, which stands for Aqueous Film-Forming Foam, is primarily used for combating flammable liquid fires. The correct answer is amber. This color indicates the presence of the specific chemical formulation that allows AFFF to effectively create a film over burning fuels, helping to smother flames and reduce the chance of re-ignition. The amber color is also a visual cue for personnel handling the concentrate, helping them distinguish it from other firefighting agents that may be clear or have different colors, ensuring correct usage in emergencies. Recognizing AFFF concentrate by its amber hue is crucial for safety and effective firefighting operations in environments where flammable liquids are present.
