What is the typical vapor pressure range for gasoline?

Gasoline typically has a vapor pressure range between 38 to 300 mm Hg at standard conditions. This range is significant because it influences the volatility of gasoline, determining how easily it forms vapors at certain temperatures. Higher vapor pressures indicate a greater tendency for gasoline to evaporate, which is a critical factor in understanding its behavior in fire scenarios, including ignition potential and flame spread.

The correct range reflects how gasoline can produce flammable vapors, especially in warm conditions, contributing to fire hazards. This characteristic is essential for both storage and handling, as it outlines the risks associated with using gasoline in various applications, including vehicles and industrial uses.

The other ranges presented do not encapsulate the true vapor pressure characteristics of gasoline, making them less relevant when assessing the flammability and volatility of gasoline in fire behavior discussions. Understanding the correct vapor pressure range helps in evaluating safety measures and effective firefighting strategies when dealing with gasoline-related incidents.
