Key Facts

Full Breakdown

Title 25 M.R.S. Chapter 313 and Office of State Fire Marshal Rule Chapter 34 adopt the National Fire Protection Association NFPA 58 Liquefied Petroleum Gas Code as the statewide standard for propane installation, storage, and use. The code sets clearance distances from buildings, property lines, and ignition sources based on tank water capacity, requires licensed installers, and mandates pressure relief and gas detection. The State Fire Marshal licenses LP gas installers and inspects bulk plants. Municipalities may not adopt less stringent rules but may add zoning controls.

Violations & Penalties

Installing or storing propane in violation of NFPA 58 carries Fire Marshal civil penalties up to $1,000 per violation, license suspension for installers, and removal orders.
