🔍 Key Concepts

• 46 CFR 30 – Shipping flammable and combustible liquids definitions • Difference between flash point and Reid vapor pressure • How Coast Guard assigns grade letters (A, B, C, D, E) based on volatility and flash point

💭 Think About

• Look at where a flash point of 80°F or below falls in the Coast Guard’s grading scale for liquids • Consider what a Reid vapor pressure of 8-1/2 psi or less tells you about how volatile (easily vaporized) the liquid is • Ask whether this description sounds more like a very volatile product (like gasoline) or a less volatile product (like heavier fuel oils)

✅ Before You Answer

• Check the exact wording in 46 CFR 30 for the definition of each grade (A, B, C, D, E) • Confirm which grade explicitly mentions flash point of 80°F or below combined with a Reid vapor pressure limit • Make sure you are not confusing this with the grade for liquids having a higher flash point or higher vapor pressure than those given in the question
