🔍 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.
