Which list correctly lists the three substances commonly cited as Class 3 liquids?

• A. Water, ethanol, methanol
• B. Gasoline, diesel fuel, acetone
• C. Gasoline, water, acetone
• D. Diesel, acetone, ethanol

Answer: (B)

Class 3 liquids are flammable liquids that have a flash point low enough to form ignitable vapors at relatively low temperatures. The three substances listed—gasoline, diesel fuel, and acetone—are a classic trio used to illustrate this category because each has a flash point well below the threshold that defines flammability danger, and they are widely cited in training materials as representative examples of flammable liquids. Water does not burn, so it isn’t a Class 3 liquid. Ethanol and methanol are also flammable, but the prompt’s familiar trio is the one commonly used to depict Class 3 liquids in many incident-response contexts.
