Appleton, WI Fire Regulations: Propane Storage (2026)

Section 4-524(k) governs gas storage tanks under the city's gas-fired equipment code, requiring that every outside storage tank for liquefied petroleum gas exceeding 500 pounds capacity rest on a solid, nonflammable footing with a gravel or stone base extending at least 2 feet beyond the tank in all directions, and that all such tanks be located in accordance with NFPA 58, the national LP-gas code. This sits within Section 4-524's broader gas-fired equipment article, which puts all gas space heating equipment and associated piping under the inspection and approval of the City Inspections Division; the Division can order a gas company or installer to disconnect equipment that does not meet the article's requirements, and the gas company must notify the Inspections Division before discontinuing service.

5 pounds water capacity (about 1 pound of LP-gas). Together, the two sections split propane regulation by scale: Section 4-524(k) for bulk outdoor storage tanks over 500 pounds, and Section 6-12(b) for small grill cylinders on multifamily balconies.
