Quick Answer
A minimum of 10 feet is required between buried propane tanks and ignition sources to ensure safe separation and prevent accidental fires.
Buried Propane Tank Installation Requirements
When installing buried propane tanks, it’s crucial to adhere to strict guidelines to ensure safety and prevent potential catastrophic consequences. The National Fire Protection Association (NFPA) and the International Code Council (ICC) recommend a minimum separation distance of 10 feet between a buried propane tank and any ignition source, including but not limited to, appliances, water heaters, and heat pumps. This separation distance is also applicable to buried tanks and fixed roof buildings.
Ignition Sources Considerations
Ignition sources include but are not limited to, appliances, generators, water heaters, heat pumps, and other equipment that may generate heat or sparks. When installing buried propane tanks near ignition sources, it’s essential to consider the type of ignition source, its power output, and the potential for accidental ignition. For example, a 1,000-watt electric water heater is considered a higher-risk ignition source than a 100-watt incandescent light bulb.
Additional Safety Considerations
In addition to the minimum 10-foot separation distance, other safety considerations include: ensuring the buried tank is at least 10 feet away from any combustible materials, such as wood or dry leaves; installing a 6-foot wide fire-resistant barrier around the tank; and using a suitable backfill material to prevent tank damage from settlement or shifting.
