Gasoline with a flash point of -45°F and Reid vapor pressure of 9.0 PSI would be classified as which grade?

Gasoline that has a flash point of -45°F and a Reid vapor pressure of 9.0 PSI falls under specific classifications based on its flammability and vapor pressure characteristics. The classification system for gasoline grades typically categorizes them according to these properties to ensure safety and compliance with regulations.

In this case, the flash point of -45°F indicates that the gasoline is highly volatile and presents a significant fire hazard, characteristic of lighter grades of gasoline. The Reid vapor pressure (RVP) indicates the vapor pressure of the gasoline at a specified temperature, and a value of 9.0 PSI is consistent with the vapor pressures seen in products that are classified as Grade B gasoline.

Grade B gasoline specifically allows for a higher flash point and vapor pressure than Grade A but lower than Grade C. Thus, given the flash point and vapor pressure provided, this gasoline is appropriately classified as Grade B.

Understanding these classifications is essential for proper handling, storage, and transportation, as different grades of gasoline entail different safety risks and requirements.
