What is an example of a grade A flammable liquid?

A Pentane
B Methyl alcohol
C Nonyl phenol
D Ethylene dibromide
AI Explanation

The correct answer is A) Pentane. Pentane is an example of a Grade A flammable liquid, which refers to liquids with a flash point below 20°F (−6.7°C). The U.S. Coast Guard regulations classify flammable liquids into different grades based on their flash points, with Grade A being the most flammable. Pentane has a very low flash point, making it a highly flammable liquid and fitting the criteria for a Grade A flammable liquid. The other options are incorrect because Methyl alcohol (B) is a Grade B flammable liquid, Nonyl phenol (C) is not a flammable liquid, and Ethylene dibromide (D) is a toxic chemical, not a flammable liquid.
