What class of fire involves Petrol, oil, and other flammable liquids?

The class of fire that involves petrol, oil, and other flammable liquids is classified as Class B. This category specifically pertains to fires fueled by flammable liquids and gases, which can include items such as gasoline, paint, solvents, and oils.

Class B fires are distinct from other classes; for example, Class A fires involve ordinary combustible materials like wood and paper, while Class C fires are related to electrical equipment, and Class D fires involve combustible metals. Understanding these classifications is crucial for selecting the appropriate fire extinguishing method, as using the wrong type can exacerbate the fire rather than control it. In the case of a Class B fire, foam, dry chemical, or CO2 extinguishers are typically recommended to effectively extinguish the flames fueled by liquids.
