Connecticut adopts the State Fire Prevention Code based on NFPA 58 and the International Fire Code, governing propane (LP-gas) cylinder storage uniformly statewide. Local fire marshals enforce, but technical standards including container limits and setbacks are set by state code.
Connecticut General Statutes Section 29-291 directs the State Fire Marshal to adopt the Connecticut State Fire Prevention Code, which incorporates NFPA 58 (Liquefied Petroleum Gas Code) and IFC chapter 61. The code establishes uniform requirements for LP-gas container storage including maximum residential cylinder size (typically 100 lbs water capacity for storage inside dwellings is prohibited; outdoor storage limits and distance setbacks from buildings, property lines, and ignition sources). Containers over 125 gallons require permits from local fire marshals using state criteria. Municipalities may enforce the code but cannot adopt amendments weaker than statewide minimums under Section 29-292.
Code violations carry fines up to $500 per day, mandatory abatement, and potential criminal liability for reckless endangerment.
