What is a key difference between Class B and Class C fire extinguishers?

The distinction that sets Class B and Class C fire extinguishers apart lies in the material they are designed to combat. Class B fire extinguishers are specifically intended for fires involving flammable liquids, such as gasoline, oil, and paints. These types of fires are fueled by combustible liquids and can spread rapidly if not handled properly.

On the other hand, Class C fire extinguishers are tailored for electrical fires. These fires can occur in scenarios involving energized electrical equipment, such as appliances, wiring, and circuit breakers. Using the wrong type of extinguisher on an electrical fire can pose significant risks, including electrocution or the fire spreading.

Hence, the correct answer highlights that Class B is designated for flammable liquids, while Class C is focused solely on addressing electrical fire hazards. Understanding this key difference ensures that individuals can select the appropriate fire extinguisher in emergency situations, promoting safety and effectiveness in fire suppression.
