Which property of AVTUR is the primary reason it is safer during spills?

• A. Higher flashpoint
• B. Lower flashpoint
• C. Higher density
• D. Lower boiling point

Answer: (A)

Fire safety in a spill hinges on the flash point—the temperature at which enough vapor forms to ignite. AVTUR has a higher flash point, so it requires a higher temperature before its vapors can ignite. Under typical spill conditions at ambient temperature, it’s less likely to reach that ignition point, making spills safer. If AVTUR had a lower flash point, ignition would be more easily possible. While density and boiling point influence how a spill behaves (how it spreads or evaporates), they don’t govern ignition risk as directly as the flash point does.
