What term is defined as a liquid having a flash point at or above 100 °F?

• A. Combustible liquid
• B. Flammable liquid
• C. Hazardous liquid
• D. Nonflammable liquid

Answer: (A)

Liquids are classified by flash point to indicate how readily their vapors can ignite. The flash point is the lowest temperature at which enough vapor is produced to form an ignitable mixture with air in the presence of an ignition source. When that flash point is at or above 100°F, the liquid is defined as a combustible liquid. This distinction helps determine how the liquid should be stored, labeled, and protected against fire hazards, since higher flash points mean lower volatility and reduced fire risk under typical handling conditions. A flammable liquid, by contrast, has a flash point below 100°F, so it doesn’t fit the 100°F criterion. Nonflammable liquid isn’t the standard term used for this particular classification, and hazardous liquid isn’t defined by this flash-point threshold.
