What is one common misconception about fire extinguishers?

• A. That they need regular servicing
• B. That they can be used on all types of fires without regard to class
• C. That they are only necessary in kitchens
• D. That they can only be used by trained personnel

Answer: (B)

The belief that fire extinguishers can be used on all types of fires without regard to class is a common misconception. Fire extinguishers are categorized into different classes based on the type of fires they are designed to extinguish. For example, Class A extinguishers are meant for common combustibles like wood and paper, Class B is for flammable liquids, Class C is for electrical fires, and so on. Using the wrong class of extinguisher can be hazardous and may make the fire worse. For instance, using a water-based Class A extinguisher on a Class B fire involving flammable liquids can cause the fire to spread, as water may ignite the flammable vapors. Understanding the classifications of fire extinguishers is crucial for effective fire response and ensuring safety.
