🔍 Key Concepts
• Fire classification system used on ships (what materials each class covers)
• What type of fuel is in a fuel oil settling tank and whether it is a solid, liquid, metal, or electrical fire
• Difference between flammable liquids, ordinary combustibles, electrical equipment, and metal fires
💭 Think About
• First, identify exactly what is burning in a fuel oil settling tank – is it wood/paper, a flammable liquid, energized electrical equipment, or metal?
• Match that burning material to the correct fire class, based on standard marine fire classifications.
• Think about which extinguishing agents are effective (foam, dry chemical, water, special powders) for that type of fuel – which class is that usually associated with?
✅ Before You Answer
• Be sure you know that Class A involves ordinary combustibles like wood, paper, and cloth.
• Confirm that Class C is linked to energized electrical equipment, not the fuel itself.
• Verify which class specifically covers flammable or combustible liquids, such as fuel oils used in ship propulsion.
