What does the AFFF symbol look like?

The AFFF (Aqueous Film Forming Foam) symbol is represented by an 18-inch green square with white 3-inch lettering. This specific design serves a crucial purpose in firefighting, as it clearly indicates the presence of firefighting agents that are effective against certain types of fires, particularly those involving flammable liquids. The use of the green color is consistent with firefighting signage, as it is easily recognizable and communicates safety and readiness.

The size and color specifications ensure visibility and standardization across different environments, making it easier for personnel to quickly identify AFFF systems during emergency situations.
