🔍 Key Concepts

• AFFF (Aqueous Film Forming Foam) is primarily designed for hydrocarbon fuel fires (Class B) • Compatibility of foam and dry chemical agents in combined firefighting attacks • Which fire classes involve energized electrical equipment and combustible metals

💭 Think About

• First, match AFFF to the correct fire class: Is it intended for ordinary combustibles, flammable liquids, electrical equipment, or combustible metals? • Ask yourself which fire types are specifically dangerous or ineffective for water‑based or foam agents. • Consider which agents are known for chemical chain‑breaking action (like Halon) and whether AFFF works by that same mechanism or a different one (smothering/sealing fuel).

✅ Before You Answer

• Identify whether AFFF is water-based, and think about how that affects use on electrical and metal fires. • Recall that Halon and similar agents work mainly by interrupting the combustion chain reaction; verify whether AFFF does this or works by creating a film over the fuel surface. • Check if standard marine firefighting doctrine allows combined (joint) application of foam and dry chemical on flammable liquid fires.
