The correct answer reflects the standard regulations regarding the safe positioning of LP gas containers. According to the ASME (American Society of Mechanical Engineers) guidelines, the outside bottom of a horizontal LP gas container must be no more than 12 inches above ground level. This height requirement is in place to ensure safe operation and minimize the risk of damage or accidents, such as leaks or spills that could occur if the container is improperly positioned.

This specification is important for several reasons, including facilitating proper drainage and reducing the potential for vapor accumulation, which could pose a risk in the event of a leak. Adhering to this guideline helps ensure the safe storage and handling of LP gas, which is critical for both residential and commercial applications. Understanding these standards is essential for professionals in the field, as they directly impact safety protocols and compliance with regulatory requirements.
