At what height above grade is an outdoor motor fuel gasoline dispensing pump considered a Class I, Division 2 hazardous location?

12 inches
18 inches
24 inches
36 inches

The correct answer is: 18 inches

A gasoline dispensing pump is classified as a Class I, Division 2 hazardous location when the height of the pump is above 18 inches from grade level. This classification is significant because it pertains to areas where flammable gases or vapors may be present due to the potential for leaks or spills, particularly in environments dealing with flammable liquids like gasoline. In outdoor settings, the specific height threshold of 18 inches is critical because it marks the point above which vapors or gases may accumulate and create hazardous conditions. This regulation ensures that any potential ignition sources, such as electrical equipment, are kept at a safe distance from these hazardous areas. Understanding these classifications helps ensure compliance with safety standards and regulations, protecting both the facility and personnel who may work in proximity to the dispensing pumps.
