🔍 Key Concepts

• Class A fires definition and typical extinguishing agents • Behavior of water, foam, CO₂, and dry chemical on ordinary combustibles like wood and paper • What is most practical on board for large amounts of burning dunnage

💭 Think About

• What are class A materials made of, and what type of agent removes heat best from this kind of fire? • Which option would be least likely to provide lasting cooling and more likely to allow re‑ignition? • On a ship, if you have a large pile of burning wooden dunnage, which agent could soak into the material and reach deep-seated embers?

✅ Before You Answer

• Confirm what Class A fires are (ordinary combustibles like wood, paper, cloth). • Match each choice with the type of fire it is best suited for (Class A, B, C, etc.). • Check which agent can provide cooling and thorough penetration into burning dunnage, not just smother the surface.
