What minimum distance must a fill pipe be from a building opening at the same or lower level?

The minimum distance a fill pipe must be from a building opening at the same or lower level is 2 feet. This requirement is laid out to ensure safety and prevent potential hazards associated with the entry of fuel or other liquids into the building. A fill pipe that is positioned too close to a building opening increases the risk of spills or leaks entering the structure, which could lead to fire hazards or environmental contamination. By situating the fill pipe at least 2 feet away, it provides a safer buffer zone that helps mitigate these risks, thus enhancing overall safety standards in construction and operation.
