Question 768 Deck General

The correct answer is B) 155°F. The flash point is the lowest temperature at which a liquid gives off enough vapor to form an ignitable mixture with air. Liquids with a flash point of 140°F or higher are considered Grade E combustible liquids. The flash point of 155°F falls within this range, indicating a Grade E combustible liquid. The other options are incorrect because: A) 80°F is too low and would indicate a flammable liquid, C) 140°F is the lower limit for a Grade E combustible liquid, and D) 75°F is too low and would also indicate a flammable liquid.
