🔍 Key Concepts

• Fire classes (A, B, C, D, K) and what type of fuel each one involves • Difference between ordinary combustibles, flammable liquids, electrical fires, and metal fires • Typical examples of fuels found on vessels and which class they fall into

💭 Think About

• Ask yourself: Is oil considered a solid material like wood or paper, a liquid that burns, an energized electrical source, or a combustible metal? • Think about what type of fire extinguishing agent you would normally use on an oil or fuel spill fire aboard a vessel. • Match the common shipboard fuel (diesel, lube oil, fuel oil) with its correct fire class from your basic firefighting training.

✅ Before You Answer

• Know that Class A involves ordinary solid combustibles (like wood, paper, cloth). • Know that Class C is specifically for energized electrical equipment, and Class D is for combustible metals. • Confirm which class is defined by flammable or combustible liquids and greases in your firefighting reference.
