🔍 Key Concepts
• Classes of fire (A, B, C, D, K) and which ones involve solid combustibles vs. flammable liquids or cooking oils/grease
• The effect of using water on flammable liquid fires and grease fires (spread vs. extinguish)
• The typical recommended extinguishing agents for galley, fuel, and paint locker fires compared with ordinary combustibles
đź’ Think About
• Which of these choices involves ordinary solid materials (like wood, cloth, paper) that water can safely cool and soak?
• For each option, ask: If I put a straight stream of water on this, will it put the fire out or scatter/spread the burning material?
• Where would foam, dry chemical, or CO₂ be safer than a straight water stream, and why?
âś… Before You Answer
• Confirm which fire class water is normally recommended for (think: wood, paper, cloth).
• Eliminate any option where water could spread flammable liquid or grease, pushing it to new areas.
• Consider which compartment (galley, fuel oil space, paint locker, berthing) would most commonly use specialized extinguishers instead of a straight stream of water.
