What type of fire does a Class B fire classification involve?

• A. Fires involving electrical equipment
• B. Fires involving flammable solids
• C. Fires involving flammable liquids and gases
• D. Fires caused by cooking equipment

Answer: (C)

A Class B fire classification involves fires that are fueled by flammable liquids and gases. This category includes materials such as gasoline, oil, grease, and solvents, which are common in many industrial and residential situations.

Understanding this classification is crucial for proper fire response and prevention strategies. For instance, water is ineffective and can be dangerous when used on Class B fires, as it can spread the burning liquid. Instead, extinguishing agents like foam, dry chemical, or carbon dioxide are recommended for suppressing these types of fires, as they create a barrier between the fuel and the oxygen needed to sustain combustion.

Knowledge of Class B fires helps in choosing the right fire extinguishers and implementing effective safety measures in environments where flammable liquids and gases are present.
