🔍 Key Concepts

• Classification of combustible vs flammable liquids under U.S. regulations • Typical flash points of gasoline, naphtha, benzene, and bunker C • Which grades (A, B, C, D, E) are associated with higher vs lower flash points

💭 Think About

• Think about which of these products normally has the highest flash point (ignites at the highest temperature). • Ask yourself: which of these liquids is usually heated to flow or pump, and what does that say about its grade? • Consider which substances are typically treated as high fire‑risk, very volatile fuels versus heavy, slow‑to‑ignite oils.

✅ Before You Answer

• Verify which grade (A–E) is associated with the least volatile / highest flash‑point combustible liquids. • Check typical flash‑point ranges: gasoline and naphtha vs benzene vs bunker C. • Confirm which of the listed products is normally a heavy residual fuel oil rather than a light distillate.
