Grade E combustible liquids have a flash point of _______________.

A 150°F or above
B 60°F to 100°F
C 80°F to 150°F
D 90°F to 120°F
AI Explanation

The correct answer is A) 150°F or above. The flash point of Grade E combustible liquids is 150°F or above, as per the U.S. Coast Guard regulations. Combustible liquids are classified into different grades based on their flash point, with Grade E having the highest flash point. The flash point is the minimum temperature at which a liquid gives off vapor in sufficient concentration to form an ignitable mixture with air near the surface of the liquid. Liquids with a flash point of 150°F or above are considered Grade E combustible liquids, making option A the correct answer. The other options are incorrect because they do not align with the flash point range for Grade E combustible liquids. Option B (60°F to 100°F) corresponds to flammable liquids, while options C (80°F to 150°F) and D (90°F to 120°F) do not accurately reflect the flash point criteria for Grade E combustible liquids.
