Full Breakdown

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.

Violations & Penalties

Code violations carry fines up to $500 per day, mandatory abatement, and potential criminal liability for reckless endangerment.

Frequently Asked Questions

Can I store a 20-pound propane tank inside my Connecticut home?

No. The state fire code generally prohibits storing LP-gas cylinders inside dwellings. Tanks must be stored outdoors, upright, in a ventilated location away from ignition sources.

Do Connecticut towns set their own propane rules?

Towns enforce the state fire code through local fire marshals but cannot adopt weaker standards. Technical requirements for LP-gas storage are uniform statewide under CGS 29-291.
