Q

Which flash point would indicate a grade D combustible liquid?

🔍 Key Concepts

• Flash point ranges used to classify combustible liquids by grade under 46 CFR (Grades C, D, and E) • The difference between flammable liquids (lower flash points) and combustible liquids (higher flash points) • Where grade D fits in the overall progression from more hazardous to less hazardous cargoes

💭 Think About

• First decide which of the four temperatures are clearly too low to be considered combustible rather than flammable. • Then decide which temperature is so high that it would fall into a less hazardous grade than grade D. • Think about the approximate flash point range that separates grade D from the next lower and next higher grades, then match that range to the closest option.

✅ Before You Answer

• Verify the definition and flash point range for grade D combustible liquids in 46 CFR Part 30 (grades of liquid cargo). • Check which answer choices fall below 80°F, which are between about 80°F and 150°F, and which are above about 150°F. • Confirm which temperature would still be considered grade D rather than moving up into grade E or down into grade C/flammable.
