The choice of Class B fires is correct because these fires specifically involve flammable liquids and gases. Class B fires can include substances like gasoline, oil, paint, and other hydrocarbons. When dealing with flammable liquids, it’s essential to understand that these materials can burn rapidly and produce significant heat, creating explosive environments if not handled correctly.

Class A fires involve ordinary combustibles such as wood, paper, and textiles. Class C fires are related to energized electrical equipment, while Class D fires pertain to combustible metals like magnesium and titanium. Each class has its distinct characteristics and requires specific extinguishing agents, making it important for firefighters to recognize the type of fire they are responding to. In summary, Class B is the correct classification for fires involving flammable liquids due to the chemical nature of these substances and the specific fire-fighting techniques required for safe and effective suppression.
