🔍 Key Concepts

• Fire class definitions for common materials, flammable liquids, electrical fires, and metal fires • What burns in a galley grease fire—the pan, the stove, or the fuel in the pan? • The difference between flammable liquids and solid combustibles like wood or paper

💭 Think About

• Think about what is actually on fire when cooking oil or grease ignites in a pan. Is it a solid, a liquid, an electrical source, or a metal? • Match that burning material to the correct fire class: which class covers ordinary combustibles, which covers liquids like fuel or oil, which covers energized electrical equipment, and which covers combustible metals? • Ask yourself: which type of extinguisher is normally recommended for kitchen grease fires, and what class of fire is that extinguisher designed for?

✅ Before You Answer

• Know that Class A is ordinary combustibles like wood, paper, cloth, and some plastics • Know that Class C involves energized electrical equipment, not the food or grease itself • Know that Class D is for combustible metals like magnesium, sodium, or aluminum—not common galley materials
