Does gasoline readily generate flammable vapors?

1. True

2. False

3. Only in enclosed spaces

4. Only when heated

The correct answer is: True

Gasoline does indeed readily generate flammable vapors, making the answer true. This property is essential to understand when working with gasoline, especially in contexts such as fueling operations or during storage and transportation. When gasoline is exposed to air, it evaporates and produces vapors that are highly flammable. These vapors can ignite easily in the presence of a spark, open flame, or even high temperatures, leading to fire hazards. This characteristic underscores the importance of proper safety measures, such as ensuring adequate ventilation when handling gasoline and avoiding sources of ignition. While it's true that gasoline vapors can become more concentrated in enclosed spaces or at elevated temperatures, the fundamental nature of gasoline is that it can generate dangerous vapors under normal conditions. Therefore, handling it with caution is imperative to ensure safety.
