🔍 Key Concepts

• Fire classes (A, B, C, D) and what type of material each one covers • What dunnage usually consists of on a cargo vessel (think about the material) • Which fire class involves ordinary combustibles like wood, paper, cloth

💭 Think About

• First, identify what dunnage is made of on most ships. Is it a solid combustible, a flammable liquid, an electrical component, or a metal? • Match that material to the correct fire class definition: which class covers common solid materials that leave ash? • Ask yourself: would this fire be fought with water and foam, or would that be dangerous because of fuel, electricity, or metal?

✅ Before You Answer

• Be sure you know that class B is associated with flammable liquids and gases • Remember that class C involves energized electrical equipment, not just anything near electricity • Confirm that class D is reserved for certain combustible metals, which are not typical materials for dunnage
