Which fire extinguisher classification is focused on flammable gases?

• A. Class A
• B. Class D
• C. Class E
• D. Class B

Answer: (D)

The classification that specifically addresses flammable gases is Class B. Class B fire extinguishers are designed to combat fires involving flammable liquids and gases, such as gasoline, oil, propane, and paints. These types of fires are particularly hazardous because they can spread rapidly and might require specific extinguishing agents to control or extinguish effectively. Class D extinguishers, while also important, are focused exclusively on combustible metals, which are different from flammable gases. Class A extinguishers are intended for regular combustibles like wood and paper, while Class E, although sometimes used informally in various regions to categorize fires involving energized electrical equipment, is not an official classification in many standards. Thus, Class B clearly stands out as the appropriate choice for fires involving flammable gases.
