70% to pass

Grade E combustible liquids are those having flash points of _______________.

A 80°F or less
B 150°F or greater
C greater than 115°F and less than 150°F
D greater than 80°F and less than 115°F
AI Explanation

The correct answer is B) 150°F or greater. Grade E combustible liquids are those having flash points of 150°F or greater, as defined in the regulations governing the US Coast Guard Captain's License Examinations. This is because liquids with flash points above 150°F are considered less volatile and pose a lower fire risk compared to more flammable liquids with lower flash points. The other options are incorrect because: A) 80°F or less would be considered a flammable liquid, not a combustible liquid; C) greater than 115°F and less than 150°F is the definition for Grade D combustible liquids; and D) greater than 80°F and less than 115°F is the definition for Grade C combustible liquids.
