Is it safe to store the propane tank inside the base of a fire pit table?
Only if the table was designed for it — meaning a dedicated, ventilated tank compartment — and only for the tank in use. Sealing a cylinder inside an unventilated base is how leaked propane pools beneath a running burner. Spare tanks never go inside anything, and a permanent fire pit is better served by a buried line with no tank near the flame at all.
Propane sinks — that's the whole issue
Propane is heavier than air. When a fitting weeps or a valve is left cracked, the gas doesn't drift off on the breeze — it slides downward and pools in the lowest enclosed space it can find. If that space is the sealed cabinet of a fire pit table with a burner running eighteen inches above it, you've built the delayed-ignition scenario on purpose. That's why every legitimate fire pit table with a tank compartment ventilates it: openings low in the cabinet so any leaked gas drains out instead of accumulating.
Using a tank enclosure the way it was engineered
If your table came designed for an internal cylinder, use it as designed: tank upright in the factory bracket, hose and regulator routed the factory way with nothing kinked or pressed against hot metal, vent openings never blocked by a fitted cover or a wall, and the cylinder valve closed after every burn. Don't retrofit a tank into a decorative base that was never vented for one — and don't stash the spare cylinder in there either, or in the garage or basement. Spares live outdoors, upright, away from the flame.
For a permanent pit, get the tank away from the fire entirely
The cleaner solution — and what we build most out in propane country like Fairview, Candler, and Brevard — is a buried, permitted gas line feeding the pit from the home's propane system, with the tank sited at proper distance and no cylinder anywhere near the flame. Along the Asheville and Hendersonville gas mains, natural gas does the same job with no tank at all. Running either line is licensed work in North Carolina. We design it, permit it, and pressure-test it: (828) 545-0525.
