Minimum separation distance between multiple containers if aggregate capacity is 501 gallons?

• A. 15 feet
• B. 25 feet
• C. 30 feet
• D. 40 feet

Answer: (B)

When you store propane containers, how far apart they must be depends on the total amount of propane you’re keeping. For a group with a combined capacity of 501 gallons, the standard minimum separation between containers is twenty-five feet. This distance helps reduce the risk that a fire or a release on one tank will quickly affect nearby tanks, and it also provides space for safe operations and emergency access. Shorter distances, like fifteen feet, aren’t enough for this level of total capacity, while larger gaps such as thirty or forty feet are safer but exceed the minimum requirement. So, twenty-five feet is the required minimum.
