Store portable propane tanks outdoors , upright, and away from doors, windows, or ignition sources—never inside your house, basement, or vehicle. A shaded, well‑ventilated spot on a solid surface is ideal, keeping the tank within about −40°F to 120°F (−40°C to 49°C).

Quick Scoop

  • Store propane tanks outside, upright, on a stable, non-flammable surface like concrete, pavers, or a pressure-treated board.
  • Keep them in a cool, shaded, well‑ventilated area, away from direct sun and away from anything that can spark or burn (grills, fire pits, AC condensers, electrical panels).
  • Never store cylinders in your home, basement, crawlspace, or inside a vehicle; gas can pool if there’s a leak and create an explosion hazard.
  • Ideal temperature range is roughly −40°F to 120°F; in heat waves, focus on shade and airflow so the tank doesn’t sit in baking sun for hours.
  • Close the valve tightly, use the protective cap if present, and keep tanks where they won’t be knocked over or hit.

Best places to store a propane tank

  • Along an exterior wall in the yard, a few feet from the grill, with the valve closed and the tank upright.
  • On a small stand or pad: concrete paver, patio, or a level board to keep it off bare soil and out of puddles.
  • In a detached, well‑ventilated structure (like an open‑sided shed) if outdoor exposure is a problem, as long as air can freely move through.

Places you should avoid

  • Inside your living space (kitchen, closet, hallway, attached garage, basement, or apartment balcony closet).
  • In enclosed, unventilated storage units or tightly sealed sheds, where leaked gas could concentrate.
  • Next to heat sources: dryers, water heaters, space heaters, generators, vehicles that idle nearby, or open flames.

Simple storage checklist

  1. Put the tank outside on level, non-flammable ground or pad.
  2. Make sure it’s upright, with the valve turned fully off and the cap on if it has one.
  1. Check that it’s in shade or partial shade, and not trapped in a hot corner.
  1. Confirm there’s at least several feet between the tank and anything that can ignite or get very hot.
  1. Keep children and pets from playing with or climbing on the tank area.

If you’re in doubt

  • If a tank smells strongly of gas, is badly rusted, or has physical damage, keep it outdoors, upright, away from buildings, and contact your propane supplier or local fire department’s non‑emergency line for guidance.
  • Local fire codes can be stricter, especially in apartments or multi‑unit buildings, so it’s smart to check building or city rules about where to store propane tanks.
