Is it safe to store gasoline, propane cylinders, or aerosol cans in the same space as a fireplace or stove?
No — none of those belong in the same space as anything that makes fire. Gasoline vapor travels invisibly along the floor and can find a pilot light clear across the room; propane cylinders should never be stored inside the house at all; and aerosol cans rupture when they get hot. Fuels live in a detached shed — not the hearth room, not beside the stove.
Gasoline: it's the vapor that gets you
The liquid in the can isn't the hazard — the invisible vapor rising off it is. Gasoline vapor is heavier than air, so it flows across a floor like water finding a drain, and it only takes a pilot light, a relighting burner, or an ember behind a stove door to ignite a trail that leads straight back to the can. This is exactly why code requires gas appliances installed in garages to sit well off the floor — the ignition source gets lifted above where vapors pool. We see the risky version weekly in the cabins up our mountain roads: chainsaw gas and a mower can wintering in the same mudroom as the wood stove. Move them out. A detached shed or outbuilding is the right home for every drop of gasoline on the property.
Propane cylinders belong outside, full stop
This one isn't a judgment call — safety codes prohibit storing propane cylinders inside the home, and that includes the basement, an attached garage, and yes, the 20-pound grill bottle that migrated indoors for winter. A cylinder valve that seeps in an enclosed space lets heavier-than-air propane pool silently at floor level. Cylinders live outdoors, upright, away from doors and ignition sources. If your home runs on propane — Fairview, Candler, Brevard, and half the coves in between — notice that your supplier put the big tank outside in the open air. Same principle, every size.
Aerosols and the catch-all shelf
Nearly every hearth room has one: the shelf or mantel corner collecting spray lubricant, spray paint, bug spray, hairspray. Aerosol cans are small pressure vessels, and radiant heat from a stove or fireplace can over-pressurize them until they rupture — spraying flammable propellant toward the fire that heated them. Keep aerosols, along with kindling piles and stacked firewood, outside the appliance's clearance zone. Two better things to keep near the hearth room instead: a fire extinguisher mounted by the exit, and our number — (828) 545-0525 — for an annual inspection that includes a look at what's living too close to the fire.
