Which class of fire designates flammable liquids such as gasoline?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (B)

Flammable liquids such as gasoline are designated as Class B fires. This classification includes any fire that involves flammable or combustible liquids, such as oils, paints, and solvents. Understanding this classification is crucial for determining the appropriate firefighting methods and equipment needed to extinguish such fires effectively.

Class B fire extinguishers typically contain agents such as foam, dry chemical, or carbon dioxide, which are specifically designed to remove heat, smother the flames, or interrupt the fire chain reaction in flammable liquid fires. This is in contrast to Class A, which refers to fires involving ordinary combustible materials like wood and paper; Class C, which involves electrical fires; and Class D, which relates to combustible metals. Each class requires different handling and extinguishing techniques, underscoring the importance of recognizing the type of fire to respond appropriately.
