Which extinguisher type is paired with CO2 for engine space fires?

• A. Water
• B. Dry Chemical
• C. Foam
• D. Wet Chemical

Answer: (B)

Engine space fires demand an extinguisher that can handle both flammable liquids and electrical equipment in an enclosed area. Carbon dioxide alone isn’t ideal here because it can displace oxygen and doesn’t cool or penetrate fuel fires effectively, which increases the risk of reignition. That’s why a dry chemical extinguisher is paired with CO2 in this context. Dry chemical is versatile and effective on multiple fire types commonly found in engine rooms: flammable liquids (class B) and electrical equipment (class C). It works by interrupting the chemical reactions occurring in the flame and coating the fuel to prevent reignition, giving a rapid, reliable knockdown in a confined space. Other options aren’t as suitable: water can spread burning liquids, foam isn’t as effective for electrical fires, and wet chemical is designed for kitchen fats, not engine spaces.
