Quick Answer
Different types of propane can be stored under one roof, but proper separation and venting are crucial to prevent contamination and risk of explosion. This involves using approved storage tanks and following specific guidelines for mixing different propane types.
Propane Storage Basics
Propane storage requires careful consideration of tank sizing, material, and installation. For a single tank, the American National Standards Institute (ANSI) recommends a minimum tank capacity of 100 gallons for storing propane for residential or commercial use. Larger tanks or multiple tanks may be necessary for larger quantities or multiple propane types.
Mixing Propane Types
When storing different propane types under one roof, it’s essential to separate them properly to prevent contamination. The most common propane types are LP (liquefied petroleum) and LPG (liquefied petroleum gas). LP and LPG are often used interchangeably, but LPG typically contains a higher concentration of butane. To store LP and LPG under one roof, use a multi-compartment tank or separate tanks with their own venting systems. Alternatively, use a single tank designed for mixed LP and LPG storage, following the manufacturer’s guidelines.
Venting and Safety Considerations
Proper venting is critical for propane storage. Ensure that the tank is installed with a sufficient amount of clearance from any buildings or combustible materials. A 10-foot clearance is recommended for residential installations, while commercial installations may require a 20-foot clearance. Additionally, ensure that the venting system is designed to prevent backdrafting and is equipped with a flame arrester to prevent spark ignition. Regular inspections and maintenance are also necessary to ensure safe and compliant propane storage.
