Question 700 Deck Safety

The correct answer is D) Diesel Oil. Diesel oil is considered a Class B fire, which involves flammable liquids and gases. Class B fires are typically caused by materials such as gasoline, oil, paint, and other hydrocarbon-based substances. Diesel oil, being a flammable liquid fuel, would fall under the Class B fire category. The other options are incorrect because wood (A) and paper (B) would be considered Class A fires, while magnesium (C) would be a Class D fire, which involves combustible metals.
