🔍 Key Concepts

• Fire classifications (Class A, B, C, D, K) used on vessels • The type of material that burns in a Class B fire • How different extinguishers are matched to the class of fire

💭 Think About

• First, recall what kind of materials are involved in a Class A fire and eliminate any options that match that class. • Next, think about what kind of materials are typically found as liquid fuels on a vessel and see which choice fits that description. • Consider which option would require a foam, dry chemical, or CO₂ extinguisher rather than plain water.

✅ Before You Answer

• Identify which option is a flammable liquid rather than a solid combustible material. • Confirm that you are not mixing up Class B (flammable liquids) with Class C (electrical) fires. • Check your memory of standard fire classes used on USCG exams: A = ordinary combustibles, B = flammable liquids, C = energized electrical equipment.
