Having an extra propane tank on hand can be very convenient, especially if you use propane frequently for heating, cooking, or other purposes. However, propane tanks must be stored properly to avoid potential hazards. In this article, we will discuss the pros and cons of various storage options to help you determine the safest place to keep your spare propane tank.
Should you store propane tanks indoors or outdoors?
Many people’s first instinct is to store a spare propane tank in the garage or basement where it is easily accessible. However, this is generally not recommended, as propane is flammable and keeping it indoors can pose risks. The National Fire Protection Association states that propane tanks should not be stored in a building, garage, basement, crawlspace, shed, or other enclosed area [1]. Instead, it is safer to store spare tanks outdoors.
Some advantages of outdoor propane tank storage include:
– Reduced risk of explosion or fire. Storing propane outdoors eliminates the risk of gas leaks and explosions inside the home. Propane is denser than air, so any leaks will dissipate outdoors rather than collect in an enclosed space.
– Better ventilation. Outdoors, there is ample air circulation to dissipate any leaked gas. Indoors, leaked gas could build up and cause an explosion hazard.
– Avoiding building code violations. Most building codes prohibit propane storage indoors or in attached structures like garages. Storing tanks outdoors complies with codes.
– Peace of mind about safety. Keeping propane outside provides significant safety benefits for your home and family.
The main downside to outdoor storage is that the tanks are exposed to weather elements, including potential corrosion and damage from sun exposure. However, proper precautions can mitigate this risk (more on this later). Overall, the safety reasons overwhelmingly favor keeping spare propane tanks outside.
Where are the best places to store a propane tank outside?
When selecting an outdoor location for propane storage, keep these guidelines in mind:
– At least 10 feet from buildings and air intake vents. This creates a safety buffer in case of leaks or explosions.
– Away from ignition sources like grills, open flames, or electrical outlets.
– In a well-ventilated area, not in an enclosed shed or space.
– Away from areas where children play.
– Not under roof eaves or overhangs where gas could collect.
– Away from damp areas like patios or pools where corrosion could occur.[2]
With these criteria in mind, some ideal places to store extra propane tanks include:
– In a propane tank enclosure or locker specifically designed for the purpose. These protect the tank from weather and provide good ventilation. They are available from hardware stores and online retailers.
– Against an exterior wall of the home, at least 10 feet from doors, windows, appliance vents, etc. This puts the tank close by for convenience but keeps it far enough away from openings.
– At the edge of your property near the propane tank hookup point, if you have an on-property filling station. This avoids long hose runs during tank refills.
– In your side or back yard on a level surface, well away from areas where people gather.
– On a back deck or patio, as long as it’s at least 10 feet from the home.
– In a detached shed or workshop beyond the 10 foot clearance zone. The building must be well ventilated.
Avoid placing spare tanks near trees/branches that could fall on them in storms, or in areas like sloped yards where the tank could roll or tip over. Select a level, stable surface.
What’s the best way to store a propane tank outside?
Once you select an ideal outdoor spot, follow these tips for safe propane tank storage:
– Keep the tank upright and firmly in place. Use brackets, chains, or straps secured to a wall or post to prevent tipping and rolling. Never store tanks horizontally.
– Place the tank on a flat, stable surface like concrete, pavers, gravel, or composite decking. Avoid direct contact with soil or vegetation.
– Use plastic or wood panels beneath the tank to prevent corrosion from wet ground.
– Protect the tank valve from bumps and damage, which could cause leaks. Turn the valve away from yard traffic areas.
– Allow space around all sides of the tank for ventilation and gas dissipation.
– Install protection like a cover, enclosure, or fencing to protect the tank from weather, falling objects, and tampering.
– Consider locking outdoor tank storage areas or using lockable propane covers for added security.
– Post “No Smoking” signs around propane storage areas along with the fire department’s phone number.
– Avoid painting tanks different colors, which can disguise leaks. Rust should be visible indication of leaks.
Proper outdoor storage arrangements like these will help keep your spare propane supply safe and secure.
How can I protect an outdoor propane tank from weather and corrosion?
When tanks are left outside, the elements can take a toll over time. Here are some ways to minimize weathering and corrosion on your spare propane tank:
– Keep it repainted – Fresh paint protects the steel tank from rusting. Spot paint any scratches or damaged areas.
– Use a cover or enclosure – A snug tank cover protects from rain, snow, UV rays, falling debris, etc. Ventilated enclosures work even better.
– Place it on risers – Wood or composite risers elevate the tank above wet ground or snow accumulation.
– Add padding underneath – Placing the tank on wood, Styrofoam or recycled pads minimizes corrosion from below.
– Use plastic wraps or shields – Special tank wraps help control exposure to moisture and abrasion.
– Install anodes – Sacrificial anode rods attached to the tank actively inhibit corrosion by absorbing it instead.
– Consider galvanized or stainless steel tanks – More expensive but naturally corrosion resistant.
– Bring tanks indoors in severe weather – Only very briefly, and only when necessary during storms or winter.
– Monitor condition and do leak checks – Periodically inspect tanks for any signs of rust, damage or leaks.
With the right combination of precautions, an outdoor spare propane tank can maintain good condition for years of safe service. Proper storage and care are vital for getting the longest life from your tank investment.
How often should I check or replace backup propane tanks?
Industry experts recommend checking spare propane tanks at least 2-3 times per year [3]. Follow these guidelines for tank inspection and replacement:
– Do a thorough visual inspection every 3 months. Look for dents, rust, bulges, leaks and valve damage. Confirm nothing will impede safe operation.
– Do an annual leak check using a commercial leak detector solution or soapy water. Ensure there are no leaks at the tank valves or fittings.
– Weigh tanks annually to check for loss of propane. A 10% unexplained drop in weight could indicate a slow leak.
– Replace rubbers hoses and fittings every 5 years. Cracking from age can cause gas leaks. Use only approved propane parts.
– Adhere to tank expiration dates, which are 12 years for steel tanks and 20 years for fiberglass [4]. Expired tanks should be removed from service and replaced.
– Replace any tank that fails inspection due to damage, leaks or other safety issues. Do not attempt DIY repairs on tanks.
– Always have tanks requalified by a licensed propane provider after any major repairs or modifications.
Following this inspection schedule ensures your spare propane tanks stay in safe, working order. Never use damaged or expired tanks, which pose significant hazards.
How can I safely transport and handle propane tanks?
When you need to move propane tanks, follow these safe handling tips:
– Transport tanks upright and secured in an approved carrier, trolley or cage designed for propane. Never transport in a passenger area.
– Make sure tank valves are closed tightly to avoid leaks and damage in transit. Use valve covers if available.
– Load and unload tanks carefully without dropping, and position them carefully in the storage area. Avoid falls onto hard surfaces.
– Never roll, drag or slide tanks, which can loosen fittings and cause leaks. Always fully lift and place tanks.
– Leave 20-30% capacity in tanks during transport to allow for expansion if temperatures rise [5]. Never transport completely full tanks.
– Drive slowly and avoid sudden stops/turns when transporting tanks.
– Avoid leaving tanks in direct sun or unattended in vehicles, where heat buildup can occur.
– Wear leather gloves and close-toed shoes when handling tanks to prevent injury if valves or fittings are damaged.
– Use caution when connecting and disconnecting regulators. Avoid cross-threading.
– Ensure adequate ventilation when transporting and handling tanks.
Careful propane tank handling habits are crucial for avoiding costly leaks and accidents. Always put safety first when moving tanks.
What codes apply to propane tank storage and handling?
There are some key codes and standards that provide guidance on propane system safety, including tank storage:
– **NFPA 58** – National Fire Protection Association standard on liquefied petroleum gases, including propane [6].
– **IFC 6104** – International Fire Code requirements for propane tank location, design, installation and transportation [7].
– **ASME Tank Specification** – Construction standards for propane tanks from the American Society of Mechanical Engineers [8].
– **DOT Cylinder Specification** – U.S. Dept. of Transportation requirements for propane cylinders and requalification [9].
– **OSHA 1910.110** – Occupational Safety & Health Administration standard for storage and handling of liquefied petroleum gases [10].
– **Local city/county fire codes** – Many municipalities have their own propane tank ordinances. Check with your local fire department.
Key requirements include 10 foot separation from buildings, no indoor storage in dwellings, appropriate tank restraints, certified tank reinspection every 12 years, approved transportation methods, and licensed personnel for tank installation. Following the codes helps ensure propane systems are safe for public use. Tank owners can be held liable if violations lead to accidents or damage.
Should I tell my home insurer that I store a propane tank outdoors?
Yes, it is wise to inform your insurance company when you store a spare propane tank on your property. This serves multiple purposes:
– It makes the insurer aware of any enhanced property risk from having propane present. Certain coverage limits or exclusions related to flammable gases may apply.
– It provides documentation that your propane setup meets code and is not an unauthorized hazard. This protects you if an incident occurs.
– The insurer can confirm you are following proper storage location and safety precautions based on code.
– Premiums can be adjusted if needed to account for the presence of propane systems. This avoids problems at policy renewal.
– Early disclosure puts you in the best position if a claim involving your propane system ever occurs. There won’t be accusations of misrepresentation.
– The insurer may have helpful risk management advice related to outdoor tank storage locations, protective enclosures, securing tanks, etc. Their expert input can further protect your property.
Being transparent with insurance companies about propane systems helps ensure you have appropriate coverage and avoid potential legal issues after a loss. They have a vested interest in your storage setup being safe and responsible.
