🔍 Key Concepts

• Grades of crude oil as used in maritime pollution and cargo classification (often tied to volatility and flammability) • Difference between light, medium, and heavy crude oils in terms of how easily they evaporate or spread • How dangerous cargo classifications (A, B, C, D, E) generally progress from most hazardous to least hazardous

💭 Think About

• Think about whether most crude oils are considered highly volatile and extremely dangerous, or somewhat less volatile but still hazardous. • Ask yourself: are most crude oils closer in behavior to gasoline (very light and volatile) or to heavier fuel oils (thicker, less volatile)? • Consider how regulations tend to group “most” crude oils: are they usually put into the very highest danger category, or one step down?

✅ Before You Answer

• Verify which grade letter(s) are typically associated with crude oil cargoes (not refined gasoline or diesel). • Check how the hazard level decreases as you move from Grade A toward Grade E and where crude oil generally sits on that scale. • Confirm whether most crudes are treated as intermediate hazards rather than the very lightest or heaviest grades.
