What is the flash point of gasoline?

The flash point of gasoline is indeed around -45°F. The flash point is the lowest temperature at which the vapors of a combustible liquid will ignite when exposed to an open flame or spark. Gasoline, being a highly volatile fuel, has a low flash point, which is why it can easily ignite even at relatively low temperatures. This characteristic is crucial for understanding gasoline's behavior in storage, transportation, and firefighting scenarios.

Other temperatures listed, such as -30°F, -50°F, and -60°F, are either too high or too low to accurately represent gasoline's flash point, underscoring the importance of knowing the specific properties of fuels when dealing with fire safety and emergency response. Understanding the correct flash point helps in assessing risks and formulating safety procedures when handling gasoline.
