Q

Any combustible liquid having a flash point of 150°F or above is grade __________.

🔍 Key Concepts

• Flash point definition and why 150°F is an important dividing line in the grading system • How combustible liquid grades (A, B, C, D, E) are organized by flash point ranges in 46 CFR • Which grades are used for more volatile vs less volatile combustible liquids

💭 Think About

• Ask yourself: as flash point temperature goes UP, does the grade letter tend to move toward the beginning or the end of the alphabet? • Think about which grade would be reserved for the least hazardous (highest flash point) combustible liquids in the list A, B, C, D, E. • Consider whether a liquid that only ignites at or above 150°F is more or less dangerous than one that ignites at 80°F, and which grade would likely reflect that lower risk.

✅ Before You Answer

• Verify in 46 CFR how flash point ranges are assigned to each grade (A through E). • Confirm which grade corresponds to the highest flash point range for combustible liquids. • Make sure you distinguish between flammable liquids (low flash point) and combustible liquids (higher flash point) before picking the grade.
