🔍 Key Concepts

• 46 CFR Part 30 – General provisions for tank vessels • How cargo grades are classified for petroleum products carried on tank vessels • The safety properties of cargoes that matter most for fire and explosion risk

💭 Think About

• Ask yourself: when the Coast Guard assigns cargo a grade (A, B, C, D, E), is it usually about how good the product is, or how dangerous it is? • Which physical properties of petroleum products are directly tied to how easily they ignite or form explosive vapors? • Think: what measurements would regulators use to group gasoline, kerosene, and heavy fuel oil into different hazard categories?

✅ Before You Answer

• Identify which option deals with fire and explosion characteristics, not commercial quality. • Recall what flash point tells you about a liquid and why it’s crucial on tank vessels. • Check whether Reid vapor pressure is related to vapor formation and thus explosion risk, or to product quality/appearance.
