Difficulty: EasyFire Safety and Classification

In an automotive repair shop, different types of fires require specific extinguishing methods depending on the burning material. Match each fire classification to its corresponding fuel source.

  • Class A FireOrdinary solid combustibles such as wood, paper, cardboard, and clean shop rags
  • Class B FireFlammable and combustible liquids such as gasoline, engine oil, solvents, and grease
  • Class C FireEnergized electrical equipment such as shop wiring, fuse boxes, and electric power tools
  • Class D FireCombustible metals such as magnesium wheels, titanium parts, and aluminum shavings

Answer

Class A matches ordinary solid combustibles (wood, paper, rags); Class B matches flammable liquids (gasoline, oil, solvents); Class C matches energized electrical equipment (wiring, tools, panels); Class D matches combustible metals (magnesium, titanium).
Each fire classification designates a distinct fuel hazard: Class A covers ordinary solid combustibles (wood, paper, shop rags); Class B covers flammable liquids and gases (gasoline, motor oil, solvents); Class C covers energized electrical circuits and equipment; and Class D covers combustible metals (magnesium, titanium).

Step-by-Step Solution

1
Identify the standard fuel definitions for each fire classification letter.
Class A represents ash-producing ordinary combustibles; Class B represents boiling liquids/fuels; Class C represents current/electrical equipment; Class D represents combustible metals.
Fire classifications are standardized safety designations established to ensure the correct extinguishing method is applied.
2
Pair each classification label with its corresponding automotive shop fuel description.
Class A pairs with solid combustibles like paper and rags; Class B pairs with liquids like oil and gas; Class C pairs with energized wiring; Class D pairs with combustible metal components.
Matching each fire type correctly prevents dangerous reactions, such as using water on an electrical or flammable liquid fire.
