What class is a diesel fire categorized under?

A diesel fire is categorized under Class B fires. This classification encompasses flammable liquids and gases, which includes fuels such as diesel, gasoline, and oil. When dealing with Class B fires, it is crucial to understand that they require specific extinguishing agents, such as foam, dry chemical, or carbon dioxide, which are effective in suppressing fires fueled by liquids.

Class A fires involve ordinary combustible materials like wood and paper, while Class C refers to energized electrical equipment, and Class D pertains to combustible metals. Since diesel falls into the category of flammable liquids, the correct classification is Class B, making it vital for those managing potential fire hazards to recognize and respond accordingly. Understanding these classifications helps ensure safety measures and response strategies align with the nature of the materials involved, ultimately mitigating risks during a fire incident.
