70% to pass

A combustible liquid with a flash point of 90°F would be grade _______________.

A B
B C
C D
D E
AI Explanation

The correct answer is C) D. A combustible liquid with a flash point of 90°F would be classified as a Grade D liquid. According to the US Coast Guard regulations, a combustible liquid is defined as a liquid with a flash point at or above 100°F. Since the flash point of 90°F in the question is below 100°F, this liquid would be considered a Grade D flammable liquid rather than a combustible liquid. The other answer choices are incorrect because Grade B is for highly flammable liquids, Grade C is for flammable liquids, and Grade E is for liquefied flammable gases, none of which apply to a combustible liquid with a 90°F flash point.
