What is a common requirement for the foundation of aboveground LP gas containers?

The foundation of aboveground LP gas containers must be made of concrete or masonry to ensure stability and safety. This requirement is crucial because it provides a strong, durable base that can support the weight of the container and withstand adverse weather conditions. Concrete and masonry materials are non-combustible, which is significant for safety in the event of a gas leak or fire. Additionally, these materials help to prevent moisture buildup, which could lead to corrosion or structural weakness over time. Using concrete or masonry also aligns with codes and regulations aimed at promoting safety in the storage and handling of LP gas, ensuring that the installation meets industry standards.
