How far must aboveground 501-2000 gallon ASME containers be located from a building?

For aboveground containers with a capacity between 501 to 2000 gallons, the required distance for placement from a building is 25 feet. This regulation is in place to ensure safety and minimize risk in case of a leak or incident involving the LP-gas. The rationale behind the 25-foot guideline is based on various factors such as the potential for pressure buildup in the event of a leak, fire hazards, and ensuring sufficient space for emergency response. Distances are determined by the size of the storage container and the potential impact it could have on nearby structures and people.

In the context of safety regulations, maintaining this distance is critical in urban planning and safety management concerning combustible gas storage, therefore making 25 feet the correct and applicable distance for aboveground 501-2000 gallon ASME containers.
