What type of materials fall under Class B fires?

Class B fires involve flammable liquids, which include substances such as gasoline, oil, solvents, and paints. The correct identification of Class B fires is crucial for firefighting efforts, as these types of fires cannot be extinguished using water effectively. Instead, specialized extinguishing agents, such as foam, dry chemical powders, or carbon dioxide, are required to smother the flames and eliminate the oxygen needed for combustion.

Understanding that Class B fires are specifically associated with flammable liquids is essential for safety and prevention strategies on vessels or in industrial settings. Proper training on handling and extinguishing Class B fires forms a core element of safety protocols, especially within the context of STCW training, where crew preparedness can significantly influence outcomes during emergencies.
