Which class of fire is a petroleum fire classified as?

A petroleum fire is classified as Class B because Class B fires involve flammable liquids and gases. These types of fires are typically fueled by substances that can ignite and burn rapidly, such as gasoline, oils, and other hydrocarbons derived from petroleum.

In firefighting, Class B extinguishers are designed to combat these specific types of fires, often utilizing foam, dry chemicals, or carbon dioxide to smother the flames or disrupt the combustion process. The focus on preventing the spread of the fire and cooling the fuel source with the appropriate extinguishing agents is crucial in managing Class B fires effectively.

Other classes of fire include Class A, which pertains to ordinary combustibles like wood and paper, Class C, which involves energized electrical equipment, and Class D, which is related to combustible metals. Each class addresses different ignition sources and requires specific extinguishing techniques and agents, which is why identifying the correct classification is vital for effective fire response and safety measures.
