If a liquid has a flash point of 99 °F, how is it classified?

Explanation:
A liquid with a flash point is classified by how easily its vapors can ignite. If the flash point is below 100 °F, the liquid is considered flammable. Since 99 °F is just under that threshold, this liquid is categorized as a flammable liquid. Combustible liquids have flash points at or above 100 °F (with subcategories for higher ranges in NFPA classifications), nonflammable liquids have even higher flash points, and “hazardous liquid” isn’t a separate flash-point-based category. So 99 °F means flammable.
