Which flash point would indicate a grade D combustible liquid?
AI Explanation
The correct answer is B) 95°F.
The flash point of a combustible liquid is the lowest temperature at which it can vaporize to form an ignitable mixture in air. According to the regulations for the US Coast Guard Captain's License Examinations, a grade D combustible liquid has a flash point between 80°F and 150°F. Therefore, a flash point of 95°F would indicate a grade D combustible liquid.
The other options are incorrect because 40°F is too low for a combustible liquid (this would be a flammable liquid), 79°F is just below the range for a grade D combustible liquid, and 155°F is too high for a grade D combustible liquid (this would be a higher grade, such as grade E or F).
