What temperature flash point defines a flammable rating?

What temperature flash point defines a flammable rating?

• A. Less Than 100 Degrees F
• B. Exactly 100 Degrees F
• C. Greater Than 100 Degrees F
• D. 0 Degrees F

Answer: (A)

Understanding flash point helps distinguish how dangerous a liquid is in terms of ignition risk. The flash point is the lowest temperature at which enough vapor can form an ignitable mixture with air to ignite if an ignition source is present. Safety standards define flammable liquids as those with a flash point below 100°F. That boundary is what separates flammable from combustible liquids. So a liquid with a flash point below 100°F qualifies as flammable, while those with a flash point at 100°F or higher are considered combustible. Even a very low value like 0°F fits the "below 100°F" rule, so it would be classified as flammable under this standard.
