Full Breakdown

Wis. Admin. Code ch. SPS 340 incorporates the National Fire Protection Association NFPA 58 Liquefied Petroleum Gas Code as the statewide standard for propane container size, setback distances from buildings and property lines, fill protections, and licensure of LP gas suppliers. Suppliers must hold a Wisconsin Department of Safety and Professional Services credential and follow uniform installation requirements. Wis. Stat. § 101.02 grants DSPS authority over fuel gas safety, and Wis. Stat. § 101.65 generally limits municipal building and mechanical code variations from the uniform state standards, ensuring consistent propane handling rules across communities.

Violations & Penalties

Improper installation or unlicensed work can lead to DSPS orders to correct, civil forfeitures, supplier license discipline, and liability for resulting fires or explosions.
