Which concentrate is based on foaming agents other than hydrolyzed proteins and includes aqueous film-forming foam concentrates, medium- and high-expansion foam concentrates, and other synthetic foam concentrates?

• A. Synthetic foam concentrate
• B. Aqueous film-forming foam concentrate
• C. Alcohol-resistant foam concentrate
• D. Film-forming fluoroprotein foam concentrate

Answer: (A)

Synthetic foam concentrates are formulated with foaming agents other than hydrolyzed proteins, and this category includes aqueous film-forming foam concentrates, medium- and high-expansion foam concentrates, and other synthetic formulations. AFFF relies on fluorinated surfactants to spread quickly over fuels and form a stabilizing film, while expansion foams are designed to blanket large areas with foam, capabilities that come from these synthetic foaming agents. A concentrate that is film-forming fluoroprotein is rooted in a protein base with a fluorochemical film-former, so it doesn’t belong to this broad synthetic category. An aqueous film-forming concentrate is itself a type of synthetic concentrate, but the question asks for the general category that encompasses AFFF and expansion foams, which is synthetic foam concentrate.
