What does a Class B fire involve, and why does that class matter to a truck driver?
- A.Energized electrical equipment only
- B.Cooking oils in commercial kitchens
- C.Ordinary wood and paper only
- D.Flammable liquids such as fuel and oil, which are the fires a driver is most likely to face
Correct answer
D. Flammable liquids such as fuel and oil, which are the fires a driver is most likely to face
Why
Class letters tell you what is burning and what agent will work on it. Fuel, oil, and grease fires are Class B, so the extinguisher in the cab must carry a B rating, and water alone can spread a fuel fire instead of putting it out.
