š Key Concepts
⢠Fire classification system (Classes A, B, C, D) and what type of material each class involves
⢠The typical materials that make up dunnage on a vessel
⢠Which fire classes involve ordinary combustibles vs. flammable liquids vs. energized electrical vs. metals
š Think About
⢠First, identify exactly what dunnage is usually made of on a ship. Is it a liquid, solid, metal, or electrical equipment?
⢠Match the material that dunnage is made from to the correct fire class description (A, B, C, or D).
⢠Ask yourself: Would you normally fight this type of fire with water, foam, dry chemical, or a special metal extinguisher?

Before You Answer
⢠Be clear on the definition of dunnage (how itās used in cargo stowage and what itās commonly made from).
⢠Review the core definitions of Class A, Class B, Class C, and Class D fires from your firefighting module.
⢠Make sure the fire class you choose matches the state of the fuel (solid/liquid/gas) and its general type (ordinary combustible, flammable liquid, electrical, combustible metal).
