What is the maximum number of 125 gallon LP tanks that can be grouped together above ground without separation?

The correct answer is based on the regulations regarding the safe storage of liquefied petroleum (LP) gas tanks. According to industry standards and regulatory guidelines, specifically those that govern the safe installation and operation of LP gas tanks, a maximum of four 125-gallon propane tanks can be grouped together above ground without the need for separation.

This limitation is put in place to minimize potential risks associated with fire hazards, pressure buildup, and leaks. Grouping more than four tanks together may increase the risk of an incident if a leak were to occur, as it could potentially amplify the impact of a single failure. Therefore, maintaining a threshold of four provides a balance between operational efficiency and safety measures designed to protect personnel and property.

Understanding these regulations is crucial for anyone involved in the installation and management of fuel storage tanks, as compliance ensures safer handling and reduces risks associated with LP gas storage.
