A liquid with a flash point below 100°F is classified as which type of liquid?

• A. Nonflammable Liquid
• B. Combustible Liquid
• C. Flammable Liquid
• D. Ignitable Liquid

Answer: (C)

Liquids are categorized by how easily their vapors can ignite, which is defined by the flash point—the lowest temperature at which enough vapor is released to form an ignitable mixture with air. When that flash point is below 100°F, the liquid is labeled flammable. The 100°F threshold is a standard cutoff used in safety codes (like NFPA and OSHA) to distinguish flammable liquids from combustible ones. So a liquid with a flash point below 100°F falls into the flammable category. The term ignitable isn’t a formal classification in these standards, and combustible liquids are defined as those with flash points at or above 100°F.
