What is the flash point of gasoline?

The flash point of gasoline is indeed around -45°F. This temperature indicates the lowest point at which gasoline can vaporize to form an ignitable mixture in air. Gasoline, being a volatile and highly flammable liquid, has a very low flash point compared to many other common substances, which is why it can ignite easily even at low temperatures. Understanding the flash point is crucial for fire safety and hazardous materials handling because it helps in determining the risks associated with storage and transportation of gasoline.

The other temperatures listed are significantly higher than the flash point of gasoline, which means they wouldn't accurately represent the flammable characteristics of this substance. Recognizing and working with materials that have low flash points, like gasoline, is important for firefighters and hazardous materials responders to prevent fire hazards and ensure safety during operations.
