What would be the most effective agent to use to extinguish a fire in drums of flammable liquids stowed on the weather deck of a vessel?

🔍 Key Concepts

• Class B fires (flammable liquids) and which extinguishing agents work best on them • How wind and open-deck conditions affect the effectiveness of different agents • The difference between smothering the fire and cooling the containers to prevent re‑ignition

💭 Think About

• Think about which agent will stay on the burning liquid surface long enough to form a blanket and prevent vapors from escaping in an open, windy area. • Consider which agents will quickly blow away or disperse on an exposed weather deck and therefore be less effective. • Ask yourself which method both controls the burning liquid and helps reduce the chance of reflash once the flame is knocked down.

✅ Before You Answer

• Verify which agents are specifically recommended for flammable liquid (Class B) pool fires. • Check which agent is designed to form a continuous film or blanket over the fuel surface, even outdoors. • Eliminate any agents that depend on enclosure or confinement (like a tight space) to work effectively on vapor suppression.
