Which of the following best describes a Class B fire?

• A. Fires involving electrical equipment
• B. Fires caused by combustible metals
• C. Fires involving flammable liquids
• D. Fires of ordinary combustibles

Answer: (C)

A Class B fire is characterized by the involvement of flammable liquids and gases, which can include substances such as gasoline, oil, paint, and solvents. These types of fires are particularly hazardous because they can spread quickly and may produce hazardous fumes. Understanding that Class B fires are specifically linked to flammable materials is important for selecting the appropriate extinguishing agents, such as foam or dry chemical extinguishers, designed to interrupt the combustion process of these types of fuels. The other classifications refer to different types of fires. For example, fires involving electrical equipment are classified as Class C fires, while combustible metals refer to Class D fires. Lastly, ordinary combustibles such as paper, wood, and textiles fall under Class A fires. Recognizing these distinctions ensures that appropriate fire safety measures and extinguishing methods are employed in response to different fire scenarios.
