Quizplus · Accepted Answer

Class B fire extinguishers are designed to extinguish fires that involve flammable liquids such as grease, gasoline, or oil. These extinguishers contain a chemical agent that works by separating the fuel source from the oxygen, which breaks the fire triangle and extinguishes the fire. Class A extinguishers are designed for fires that involve ordinary combustibles such as wood, paper, or cloth, while Class C extinguishers are designed for fires that involve electrical equipment. Class D extinguishers are designed for fires that involve combustible metals, such as magnesium or titanium, and are not commonly found in most workplaces.
