Vehicle impact protection
Required by NFPA 58 when the tank is potentially exposed to vehicle traffic — typically near driveways, parking areas, or commercial properties. Acceptable protection methods:
- Bollards — typically 4–6 inch steel pipe, concrete-filled, set in concrete, 36+ inches above grade
- Concrete curbs — 4–6 inch poured curbs creating a barrier zone
- Strategic landscape barriers — large rocks, raised beds, fencing positioned to block vehicle access
Weather protection
- Paint maintenance — touch up every 5–10 years. Use light colours (white, off-white) to minimize heat absorption
- Cathodic protection (underground tanks) — sacrificial anode prevents corrosion; replace per manufacturer schedule
- Snow load consideration — keep tank free of heavy snow accumulation; clear vent areas and fittings
- Flood protection in flood-prone areas — anchor tank to prevent buoyant rise; verify with your dealer
Vandalism and tampering
Rare but real consideration in some areas. Mitigations:
- Locking caps on tank service and fill valves (available from dealer)
- Fencing around the tank pad — must respect NFPA 58 access requirements for the delivery truck
- Outdoor lighting over the tank area at properties prone to nighttime trespass
Natural hazard protection
- Wildfire areas: NFPA 58 requires a 10-ft clear zone around the tank; in interface zones, extend clear zone further
- Hurricane/storm zones: ensure tank is anchored per dealer specifications; clear surrounding debris before storms
- Earthquake-prone areas: California specifically requires seismic shut-off valves on residential gas systems
- Falling tree hazards: remove or trim trees that could fall on the tank
What NOT to do
- Don't enclose the tank in a building, garage, or shed — NFPA 58 prohibits indoor residential bulk tanks
- Don't paint the regulator, valves, or any fittings — paint interferes with venting and operation
- Don't store flammable materials nearby (wood piles, fuel containers, debris)
- Don't allow vegetation to overgrow the tank — visibility and fire-prevention matter
FAQ
Do I need bollards for my propane tank?
Required if vehicle impact is a realistic risk — typically tanks near driveways or roads. Not required for tanks in protected backyard locations. Your installer or dealer can advise on whether bollards are needed in your specific configuration.
Can I build a fence around my propane tank?
Yes, with two constraints: the fence must not enclose the tank (no roof or walls creating an enclosed space); and access for the delivery truck to the fill valve must be maintained (typically the dealer needs ~25 ft of clear truck access).
