What is the minimum flashpoint for F76 and JP5?

• A. 140 degrees F
• B. 120 degrees F
• C. 180 degrees F
• D. 100 degrees F

Answer: (A)

Flashpoint is the lowest temperature at which enough vapor escapes from a liquid to form an ignitable mixture with air, so an ignition source can cause a brief flame. For F76 and JP5, the minimum flashpoint required by their fuel specifications is 140 degrees Fahrenheit. That means these fuels are designed not to form ignitable vapors at temperatures below 140 F, helping prevent accidental ignition in typical operating conditions. The other temperatures are either below the required safety threshold or higher than the minimum, so they don’t represent the minimum flashpoint for these fuels.
