Question 1087Deck General70% to pass
Combustible liquids are divided into how many grades?
AI Explanation
The correct answer is B) Two.
Combustible liquids are divided into two grades according to the United States Coast Guard regulations. Grade C includes liquids with a flashpoint at or above 100°F, while Grade B includes liquids with a flashpoint below 100°F but above 80°F. This two-grade classification is based on the flammability and hazard level of the liquids, with Grade B being more flammable and hazardous than Grade C.
The other answer choices are incorrect because the regulations do not define one, three, or four grades of combustible liquids. The two-grade system is the standard classification used for these types of hazardous materials on vessels.
