Underground tanks: can be closer to buildings
The placement of fuel tanks is subject to strict guidelines to prevent fuel spills and leaks, and to minimize pollution liability. Above-ground tanks should not be placed within 25 feet of any building, according to West Bend Mutual Insurance Company's best practice recommendations. New York City Fire Code 2022 also specifies that the distance between any part of an above-ground storage tank and buildings should not be less than 50 feet.
Underground tanks, however, can be placed closer to buildings. For instance, propane tanks that hold up to 2,000 gallons can be placed as close as 10 feet from a building or property line. Larger underground tanks can be situated even closer to a house and property lines, making them a good option for those who have high fuel usage but limited yard space. Underground tanks are typically buried just under the ground, usually one or two feet deeper than the tank's height.
It is important to note that the placement of fuel tanks may be subject to local, state, or federal regulations and ordinances. For example, smaller propane tanks, those under 125 gallons, must be placed at least 10 feet from windows or air conditioners, and at least 5 feet from any crawl space openings. Similarly, tanks that receive refill deliveries must be at least 5 feet from the driveway.
Working with a professional installer can help ensure that your fuel tank is placed in compliance with safety standards and regulations, while also maintaining the aesthetic appeal of your property.

Safety relief valves: avoid awnings, overhangs, ignition sources
The distance between a fuel tank and a building depends on the type of fuel tank and the regulations of the location. For example, in New York City, the fire code mandates that the distance between any part of an aboveground storage tank and buildings or structures used for housing fire extinguishing equipment, central heating plants, or electrical distribution equipment be no less than 50 feet (15240 mm).
Now, let's focus on the topic of safety relief valves and their placement in relation to awnings, overhangs, and ignition sources. Safety relief valves are an essential safety feature of propane tanks, designed to protect the tank from rupturing in the event of excess pressure buildup. These valves are subject to specific distance rules and installation guidelines to ensure the safe venting of propane gas. Here are some detailed instructions and considerations for installing safety relief valves:
Avoid Awnings and Overhangs
Safety relief valves must be installed away from awnings, building overhangs, or any similar structures. This is because, in the event of the valve opening, propane gas will vent vertically upward. If the valve is located directly underneath an awning or overhang, the released propane could accumulate in a concentrated area, creating a dangerous situation. By installing the tank away from any obstructions above, you minimize the risk of propane buildup and potential ignition.
Maintain Clearance from Ignition Sources
It is crucial to ensure that the area surrounding the safety relief valve is clear of any potential ignition sources. This includes items such as hot water heaters, stoves, or any open flames. In the event of a valve release, propane could come into contact with these ignition sources and cause a hazardous situation. A safe distance of at least 3 meters is recommended between the propane tank and any ignition sources to mitigate this risk.
Regular Maintenance and Inspection
To ensure the proper functioning of safety relief valves, regular maintenance and inspections are vital. Both internal and external pressure relief valves (PRVs) require periodic checks for damage, wear, and proper functioning. Internal PRVs, located inside the propane tank, offer protection against overpressure and are less prone to external damage. External PRVs, on the other hand, are mounted outside the tank for easy access and are more susceptible to environmental damage. Following manufacturer guidelines for maintenance, including cleaning, part replacement, and pressure adjustments, is essential for optimal valve performance and safety.
Consider Tank Size and Location
The distance requirements for propane tank locations depend on factors such as the size of the LP Gas tank and whether it is an above-ground or underground installation. Above-ground tanks generally need to adhere to specific distance rules regarding buildings, houses, and other surrounding features. Underground tanks, on the other hand, face unique environmental challenges and have distinct regulations regarding their installation and maintenance. It is important to carefully consider the specific requirements for your tank type and size to ensure compliance with safety standards.
By following these guidelines and adhering to local regulations, you can ensure the safe installation and operation of propane tanks, specifically concerning the placement of safety relief valves. Remember to always prioritize clearance from awnings, overhangs, and ignition sources to mitigate potential hazards associated with propane venting.
