Can Propane Tanks Explode in the Sun?

Propane tanks are often used in small camping stoves and can be found at home improvements. They are made of different materials, such as steel and aluminum, and they are all under constant pressure, which can lead to catastrophic consequences if not handled properly. However, can propane tanks explode in the sun?

Propane tanks can explode in the sun. The reason is that propane is a liquid at room temperature but turns into gas when it’s pressurized. When you fill a propane tank, it’s pressurized and ready to use. But when you let the tank sit for too long while you’re not using it, the pressure inside remains high enough to explode if the temperature rises too much. 

Furthermore, propane tanks are not designed to withstand intense heat because it’s a highly flammable gas that can explode when exposed to too much heat. If you have a tank that’s been left out in direct sunlight for an extended period, the gas inside can be so pressurized with air that it can explode.

Do Propane Tanks Explode?

Do Propane Tanks Explode

Propane tanks do not explode. This common misconception started with a false urban legend claiming propane companies would set their tanks on fire and then blame the explosion on the tank itself. The truth is, there are never any reported incidents of propane tanks exploding.

People believe propane tanks explode because they associate the word “explode” with “fire.” When you hear someone say that a propane tank has exploded, they’re probably just talking about how much havoc was done to the surroundings because of a fire.

While it’s true that there have been situations where propane tanks have started fires in their storage facilities, these fires are always caused by human error or criminal activity. There have not been circumstances where a commercial facility storing propane tanks has been destroyed due to an explosion or fire caused by the propane tanks.

Can Propane Tanks Explode in Heat?

Propane tanks are often used as an alternative to the more traditional fuel sources. Propane is a gas found in most households and is easily transported by car. Also, Propane tanks are filled with propane gas, which is lighter than air. When they are filled, they will stay at their original height because there is no air in the tank. This means that if you put a small amount of weight on your propane tank, it would not expand as other fuels would.

It means that propane tanks do not explode in heat like other fuels, such as gasoline or diesel fuel. However, it does not mean they cannot cause fire or explode when heated up. This is because propane has a lower flash point than other fuels and will ignite easily in a climate below 140 degrees Fahrenheit (60 degrees Celsius).

However, they get hot when used—which can affect how the tank reacts to temperature changes. Propane tanks are made of metal, so if you leave them outdoors in the sun for an extended period, they can reach temperatures high enough to cause them to explode. It’s also possible for them to explode if they’re taken indoors and left in direct sunlight for a prolonged time.

Can Propane Tanks Explode in Cold Weather?

Propane is a gas that’s used in stoves and other appliances. When you store propane in your tank, it turns into a liquid to prevent it from freezing. But when the temperature drops below -34 degrees Fahrenheit, the liquid becomes a gas again and can cause a dangerous explosion.

If you’re storing propane tanks indoors, ensure they are kept at least three feet above any hard surfaces, even if they’re only just inches away from each other. If possible, store them in a well-ventilated area and away from flammable materials such as paper or furniture.

Never use an outdoor grill or stove with an attached propane tank indoors. It’s too dangerous. If you have children, you should never use an outdoor grill or stove with your indoor tanks because it could cause an explosion or fire.

 Will Propane Tanks Explode in a Fire?

Propane tanks explode in fire, but it’s not a guaranteed thing. It depends on the size, how much fuel is inside, and whether or not there are any released products to help slow down the explosion. The reason that propane tanks can explode in a fire is that they contain pressurized liquids. When those substances reach temperatures too high to handle without exploding, they do so with force.

Most people believe propane tanks are more likely and dangerous than gasoline or diesel fuel tanks when it comes to an explosion because propane has such a high boiling point compared to other types of fuels. 

Therefore, for a propane tank to explode in a fire, it must be punctured by fluids that contain oxygen or air (for example, if water gets into the tank). This can happen if someone cuts themselves. If enough oxygen or air escapes inside the tank, it will ignite and explode violently. 

In addition, propane tanks can explode if filled with flammable liquids. As soon as the tank is opened for any reason, there’s an automatic release valve that lets out some gas inside. Any fire or explosion at that point can set off the tank’s internal pressure and cause it to explode. This only happens when you’ve opened up a propane tank for refilling purposes; if there are no flames or other sources of heat nearby, then it won’t explode.

Is It Bad for a Propane Tank to Be in the Sun?

It’s not good to place your propane tank in direct sunlight, and it’s also not something you should sweat about. Many people think putting their propane tank in the sun will damage or degrade its contents, but the truth is that the sun has nothing to do with any issues that could arise from putting your tank in direct sunlight.

The biggest concern is heat, especially when dealing with a tank that has already been used and stored for some time.

Some tanks have special additives added to them to help prevent degradation caused by heat exposure; others are made with materials that are resistant to degradation by heat, like stainless steel. If you’re storing your propane tanks outside, in a shed, garage, or basement, and you stay the climate can get over 100 degrees Fahrenheit, it is terrible for the tank to be in direct sunlight. 

If there is no sun at all and it’s cold enough to be below freezing, this might not matter as much. This is because propane is stored through a process called phase separation.

Propane molecules are stored as a liquid under pressure until they reach their boiling point of -42 degrees Celsius (or -44 degrees Fahrenheit), which causes them to turn into gas. When this happens inside a container, it can explode if there isn’t enough pressure to force them out of its liquid state quickly enough. This happened with propane tanks that were left out in direct sunlight.

Does Propane Go Bad?

Propane is colorless, odorless, with a gas-like burning sensation. It is produced mainly from natural gas, oil shale, and coal. Propane has been used for years for cooking and heating homes.

However, it’s important to note that propane does not deteriorate slowly over time. Instead, propane can go bad quickly if it isn’t stored properly or if you use it near an incompatible source (such as a fire or open flame). 

The main reason propane goes bad is that some components of the gas lose their ability to hold on to each other.

When this happens, the chemicals can break propane and cause an explosion. This can happen during regular use or when you use your propane tank outdoors without an air filtering system. When exposed to extreme heat, propane can become volatile and explode. Store Propane tanks in a cool location away from direct sunlight or other heat sources. 

Additionally, propane tanks should be adequately maintained, so they don’t leak or develop cracks over time. If you notice that your propane tank isn’t working as well as it once did, check with your propane supplier to know if they have any recommendations for replacing your tank or any other repairs that need to be done.

Why Do Propane Tanks Freeze?

Propane tanks can freeze due to different factors, including pressure and design. When the temperature inside your propane tank drops below freezing, it can cause the interior of the tank to crystallize. This crystallization is caused by freezing water in the propane tank when it is exposed to subzero temperatures.

If you have a propane tank left outdoors during cold weather, it may also freeze because of condensation buildup on the outside of the tank. The condensation builds up due to warm air being trapped inside your propane tank and unable to escape through its vents or valves. This prevents moisture from evaporating inside your tank, causing it to freeze over time.

Additionally, suppose you have a large quantity of fuel in your propane tanks or are located close together within an area that gets very cold during the winter (such as an apartment building). In that case, there is more potential for them to freeze at once.

Another reason propane tanks freeze is that the water in the tank is either too cold or too warm. Ice crystals can form when the temperature of the water inside a propane tank is too cold. These crystals can damage the tank and cause it to crack or leak. If the tank water is warm, it could cause condensation, the process by which molecules collect on each other and turn into liquid water. 

Condensation can also cause rust on your equipment, so propane tanks should be kept away from direct sunlight and never stored under an upside-down roof.

Is It Dangerous When a Propane Tank Freezes?

A propane tank can freeze if the temperature drops below freezing, but it’s not very common. Propane tanks are made from steel and are insulated, so they don’t freeze as quickly as other types of tanks.

However, if you stay in a cold area where temperatures drop below freezing during the winter, consider bringing your propane tank indoors to prevent it from freezing.

If your tank gets too cold, it can crack and leak. If this happens, you’ll need to replace it immediately. In addition to the damage caused by frozen tanks, there are also safety concerns associated with them: You should never refill your tank until it’s been properly repaired or replaced by an authorized dealer. In addition, when a propane tank freezes, the liquid inside expands while the tank is below freezing temperatures.

As a result, the liquid expands faster than outside the tank. This can cause internal pressure to build up. If this pressure becomes too high, it could cause an explosion.

If you own a propane tank and notice that it has frozen, you should immediately turn off all heat sources in your home and storage area so that the liquid does not expand faster than its surroundings.

Also, you should ensure that no one else uses any appliances or devices with electricity or power. It would help if you opened all doors and windows as soon as possible because propane gas can escape through cracks in walls or doors during this period.

Why Do Propane Tanks Get Cold?

Propane tanks sometimes get cold because they’re out in the elements. You may have heard propane is a flammable gas, but it’s safe and doesn’t cause as much damage as other common fuels.

The most common way to get propane into your tank is by pumping it directly from a pipeline, which can be dangerous if not done correctly. In addition to keeping your tank free of debris and water, periodic maintenance helps prevent leaks and corrosion.

Also, it is also made of steel. Steel absorbs and holds heat, but it’s also conductive. That means if you put a propane tank in a cold place, it will absorb the cold and hold it until you turn up the heat on your stove. While propane tanks are often made of steel, their insulation must withstand temperatures up to 1350 degrees Fahrenheit (700 degrees Celsius). If it’s unable to do this, it can become cold.

If your tank has been empty for a while and you live in an unheated space with temperatures around freezing or below, your tank could get very cold as it absorbs energy from its surroundings to keep its contents warm.

Can You Lay a Propane Tank on Its Side?

You can lay a propane tank on its side. But you need to be careful. Properly storing your propane tank by placing it upright will help to keep it from leaking. However, if you store it on the side, you must use a secure fitting to keep the valve from being knocked out of place and leaking.

Also, you’ll need to make sure that the tank is empty. You can’t use a full tank, creating a fire hazard if the gas leaks.

Additionally, when laying the propane tank flat on a table or work surface, ensure it’s completely flat and stable. And turn off all power to the area where you’re working with propane tanks. Ensure there are no other ignition sources nearby, such as appliances or lights, that could spark an explosion.

If your home has pure gas lines nearby, disconnect them from their connections before moving your tank. Natural gas is highly flammable and could cause an explosion if you don’t disconnect it from its connection point before moving it around.

How to Disconnect Propane Tank from Grill?

How to Disconnect Propane Tank from Grill

Disconnecting the propane tank from your grill is a simple step that can be done. These are some steps you should take:

1: Turn off the valve by turning counterclockwise.

Shut off the gas valve. This is located on top of the grill, near where your propane tank connects. If it’s not there, look on the other side of the grill. It’ll be a metal lever with a circular knob on top. Pull this lever back and then push it down again until it clicks. This will turn off the gas valve and prevent any further use of propane.

2: Remove the propane tank from its mounting plate or bracket on the grill.

 If you’re looking to disconnect your propane tank from your grill, there’s no need to get out the pliers and break out a wrench. You can do it with just a hand. Pull out your long-handled tool (like pliers) and grasp the metal ring that connects your propane tank to your grill.

With one hand holding onto this ring, use your other hand to grab your propane tank’s handle (the one closest to where you connect it). With both hands wrapped around these two handles, gently pull them apart until they separate and fall away.

3: Remove any screws or bolts that secure your grill’s burner control box.

You may need to move a small, spring-loaded plate under your grills burner control box to access these screws or bolts, depending on how much space is available beneath your grills burner control box when you remove it from its mounting bracket on top of its mounting bracket.

Where to Store Propane Tank in Summer?

If you have a propane tank, you’re probably wondering where to store it when the weather gets warmer. You might want to be able to use your tank, but you also want to make sure it’s safe and secure, and that’s not always easy when the temperatures rise.

Luckily, here are some ways to keep your tank in good shape this summer. If you have a tank with a hose hookup, it’s easy to store it with the rest of your outdoor equipment in the summer. But if your propane tank doesn’t have a hose hookup, or if you want an extra outlet for other appliances, consider storing your tank in an outdoor enclosure. 

Your local hardware store should carry these enclosures, often called propane sheds or barns. They come in different sizes and styles to find one that fits your needs perfectly.

In addition, it’s essential to keep your propane tank in a cool, dry, and well-ventilated area. Propane tanks need to be stored in a well-ventilated location above ground level. Keep the tank on a wall or under a roof (not inside the house). The temperature in your home may be warm for your tank and can cause leakage.

If you don’t have access to any cool storage space inside your home or garage, consider renting a commercial space with enough cool air circulating through it so that the room temperature isn’t too hot for storing fuel tanks time of year.

Can You Leave Propane Tank Outside In Winter?

You can leave a propane tank outside in the winter, but it’s not always advisable. The first you need to do is make sure that the tank is thoroughly insulated. You can use foam around the top of the tank to keep the cold out and your heat.

Also, ensure that the outlet valve is closed tightly so no cold air can get in. If you use a chimney in your home, you can use an adapter to connect your propane tank.

This will let you use your fireplace with this propane tank without worrying about freezing temperatures freezing up your gas lines or tanks. If you stay in an area with snow on the ground all year round, this may not be required since there won’t be any need for heating or cooling systems inside your house during the winter months.

So you can leave your propane tank outside in winter, but it will be safer if you don’t. When storing your propane tank in winter, ensure that it’s securely covered with a tarp or something else to keep the cold out and protect against snow and ice.

This way, if there is any chance of a crack developing in your propane tank over time, it won’t get worse than just needing to be repaired by someone who knows what they’re doing.

How Low Can I Safely Let My Propane Tank Get?

Letting your propane tank get low means you’re going to let it empty or run out of gas. And as you know, when a propane tank empties, it needs to be refilled with new propane before it can be used again.

So, how low can you safely let your propane tank get? This is how many people run into problems. They don’t know how low they can safely let their tank get before it needs more propane. 

They might not know whether they need to top off their tank again before they empty it or if they even need an extra helping of propane. You’ll want to track how long it takes for the air in your tank to fill back up after each use. This will help you decide when to refill it. If it takes longer than 10 minutes for the air in the tank to fill back up after each use, then you probably need to refill more often than once every five days.

If it doesn’t take up to 10 minutes for the air in the tank to fill back up after each use, then you probably don’t need to refill as often. Propane tanks are safe when full, but that doesn’t mean you shouldn’t take precautions. It’s good to keep your tank topped up, and you should also ensure it has enough propane to get you through a few days.

How Long Does a 1 Lb Propane Tank Last on a Gas Grill?

The average propane tank lasts about 1.5 hours on a gas grill. That’s because propane is a very volatile fuel that only stays warm for almost that long. 

However, it’s essential to remember that the propane tank is not filled all the way up with gas, and you’ll want to fill it up about halfway before you turn on your grill. This will ensure that you have enough room for the heat generated by your grill and any average heat loss from vaporization or evaporating liquid inside the tank.

You can use a smaller propane tank if you have a smaller grill or vice versa. The size of your grill determines how much propane you need—you’ll need less propane on a small grill than on one with larger cooking areas like a kettle grill or a built-in charcoal grill. Also, how long a propane tank last on a gas grill depends on how much you use your grill and how you store it.

If you use your grill regularly and it sits in a garage or other location that is not well-ventilated, the tank will last up to 3 years before it can be replaced. If the grill is stored indoors, there is no point in storing it for more than a year at a time. 

Meanwhile, some people have reported keeping their tanks for up to two years. If you want your grill run longer, consider upgrading to a bigger tank.

How to Put Out a Propane Fire?

How to Put Out a Propane Fire

If you have a fire outbreak in your home, you must know how to put it out. There are different ways to put it out, and one is using a fire extinguisher. However, if you don’t have one at your disposal and cannot call for help, there are other ways you can try.

1. Turn off the gas valve. 

If this is not viable, turn off the gas supply line under the house or in your yard. 

2. Move away from the fire and let it burn itself out.

 Move away from open flames and get out of the area where the fire is located. If you can’t leave immediately, move as far away from any flames as possible and call 911 immediately so that the first responder can help get you out of danger.

3. Call 911

If there is no way to turn off the gas supply once out of the building, or if there are no working phone lines at your residence or business location, call 119 if you can. 

Once outside, use a garden hose with an adjustable nozzle to douse the flames. You can also use water from a bucket or even an empty soda bottle to put out the fire.

4. Removing any flammable materials 

The next step will be removing any flammable materials, such as furniture or curtains, from around where the fire occurred so that they will not catch

Now that your house has been saved from danger, it’s time for you to figure out what caused this catastrophe in the first place. If possible, take some photos of what happened to prove this was not just an accident but an actual emergency that needed immediate attention from authorities to prevent further damage or loss of life due to this unfortunate event happening within your home.

Can a Propane Tank Explode in a Hot Car?

A propane tank can explode in a hot car. Propane tanks require regular maintenance and cleaning and are susceptible to temperature changes. If you leave your tank in the heat of your car when it’s not empty, it could rupture, and a direct flame or high temperature can damage it.

So, if there is any damage to the tank itself, it can leak and create a spark that could cause an explosion. A propane tank can also explode in a hot car. If there’s not enough air pressure in a hot car, the tank will explode because there will be no oxygen available for the gas to burn off.

Therefore, the best thing is to keep your car in the shade and away from direct sunlight, which will help lower temperatures and allow for more oxygen flow into the system. You should also check for leaks before leaving your vehicle; if you see any signs of leakage, be sure to plug them immediately.

Is It Safe to Travel with Propane Tank in Car?

You can safely travel with a propane tank. However, you should constantly check the gas gauge and ensure enough gas for your trip. The car will stop running without warning if insufficient propane is in the tank.

Also, it would help if you were cautious when using a propane tank in the car. Therefore, you need to ensure that your car’s air conditioner is working properly and that your car is safe from leaking fuel. The gas inside the tank can leak, and the risk of explosion is high. When you’re traveling with your propane tank, be sure to keep it in your trunk or on a backseat shelf.

The last thing is you or anybody in your car while driving gets hurt because there was an explosion. If an explosion happens while someone is in the back seat of a vehicle during a road trip, they could quickly die or suffer serious injury. 

How to Secure Propane Tank to Grill?

How to Secure Propane Tank to Grill

Propane tanks are heavy, so they can be dangerous to transport. You’ll need tools and a few materials to secure your propane tank to your grill.

1. Remove the Propane Tank from its Tank Carrier

You must remove your propane tank from its original carrier for this process to work. You’ll have to use a wrench or socket wrench to remove this part of the tank. You should also ensure that you have some extra parts to put back together later if something goes wrong during this process.

2. Get A Solid Stand For The Propane Tank

 Get your hands on some rope or bungee cord. You can use this just like any other rope. Tie it around the tank’s top and secure it with a nail or screwdriver.

Next, you’ll want to use zip ties or hooks to attach all of the lids of the propane tanks. This will ensure that they stay closed while using them on your grill.

3. Attach the Propane Tank to Your Grill

Once you’ve removed it from its original carrier, it’s time to attach it to your grill. This is done by using two different types of screws or bolts depending on which type of grill you have and where they need to go for this part of the installation process to work properly.

If there’s no space where these screws should go, don’t worry about them; just find another way around this problem instead of trying again. 

Do Propane Tanks Explode When Shot?

 Propane tanks do explode when shot. It’s not a regular occurrence, but it does happen. A likely explosion cause of an explosion is a leak caused by a damaged valve, seal, or even a broken handle. If you notice any uncommon smells or sounds coming from your tank, take it offline immediately.

In addition, propane tanks are filled with liquid propane gas at pressure. The liquid expands when heated in the tank, vaporizing some of the propane and causing it to expand further. This expansion can cause cracks in the tank’s walls, allowing more gas to escape.

Some models of propane tanks have vents that release excess pressure when shot at by accident or intentionally by someone who doesn’t know what they’re doing. This venting can also cause damage to the tank itself or its contents if done improperly or too many times.

What to Do with Propane Tanks When Moving?

When you’re moving, there’s a lot to think about. Your house is packed, and you must get it set up in the new place as quickly as possible. But what about your propane tanks?

While this might not seem the most pressing concern at first glance, it’s worth considering before you pack boxes for your move. 

So how do you constantly keep an eye on those tanks? The first step is keeping an eye on them yourself. Ensure they’re secure and safe from any potential damage during transit or storage (ensuring they aren’t sitting in direct sunlight).

Then, once everything has been unpacked and settled, ensure everything has been appropriately disconnected from their sources of supply (including any cables connecting them), so they can’t accidentally be hooked back up again later during use.

Is It Illegal to Have a Propane Tank Indoors?

It is not illegal to have a propane tank indoors, but some laws prohibit indoor combustion in certain areas. Still, these are primarily meant for public spaces like offices or apartment buildings. Those living in those spaces can still use their propane tanks within their homes.

If you live in an apartment with other people and want to use your tank inside your home, you should consult with your landlord about whether or not it would be proper.

You should also be sure that you have permission from the building owner or manager before installing a propane tank indoors. This is especially important if there are rules about how many tanks can be installed in each unit.

Additionally, when it comes to propane tanks, some laws apply to them even if they’re indoors. A propane tank inside your house can be illegal if you live or work in a home or building with more than two floors.

However, most propane tanks are not very big and can fit easily into corners and closets in your home. Additionally, many states have passed laws allowing homeowners with smaller tanks to keep them outdoors for cooking or heating their homes in cold weather conditions.

Should You Turn Off the Propane Tank After Grilling?

You should put off your propane tank after grilling. Doing so will reduce the chance of a gas leak and ensure that your grill is safe for use in the future.

Fires caused by careless handling of propane tanks are not uncommon. If you enjoy the smell of their grills after they’ve been used, then you should turn off your propane tank before storing it away.

You should turn off the tank after using it because it can be dangerous if left without being off. Another reason you should turn off your grill after using it is that there are many dangers associated with leaving a propane tank on while still being filled with gas.

And if your grill was left on while being filled with gas, there’s a chance that someone could get hurt because they might trip over the hose or run into something else.

 Also, they could be seriously injured if someone were to run into something while trying to remove the hose from their grill. If your grill was on while being filled, there’s also a chance that someone could get hurt.

How to Prevent Propane Tank from Freezing?

There are so many ways to stop your propane tank from freezing. The most important thing is to keep the tank clean and covered, so water doesn’t get in and cause rust.

1. Never store a propane tank where it will freeze. It should be stored in an unheated garage or shed during cold weather. This will prevent any damage to the tank and ensure it remains operational even during extreme temperatures.

2. If you are going to leave your tank outside, put it in a heated building or garage that has plenty of ventilation so that condensation does not build up inside the tank and freeze up around the valves or seams where they meet the body of the tank itself (the bottom).

3. Try not to use your tank when it’s freezing out. This could cause condensation buildup on top of your tank, causing rust stains and corrosion, eventually leading to the failure of some parts within your tank overall.

Does Cold Weather Affect Propane Tanks?

Cold weather can affect propane tanks. The cold affects the gas molecules in the tank, which can cause it to freeze and harden. This can result in a leak or leaky tank, which can be dangerous if you have open flames at home. 

If your tank is losing pressure, check the propane gauge on the tank itself. You’ll need to check this gauge every day during the winter months, but especially in the early spring and fall.

And if there’s no pressure reading present, then something may be wrong with your tank, and you should contact a propane repair professional immediately. If you see any leak in the line between your tank and regulator (or vice versa), there’s a good chance that cold weather has caused it.

This can happen if an air gap forms between the two pieces of equipment when temperatures drop below freezing or below 32 degrees Fahrenheit (0 degrees Celsius). Once this happens, there will be no way for any gas from your tank to reach your regulator—which means there’s no way for it to flow through your system and into the home where it belongs. 

This means all appliances in that space could stop working if they’re connected directly to those pipes.

How Much Heat Can Propane Tank Withstand?

How Much Heat Can Propane Tank Withstand

How big your tank is and how much heat you put into it. E.g., if you have a small tank and you’re using it for cooking, you’ll probably want to keep it in your kitchen and not put any heat source inside. 

But if you have a large tank and are heating water for bathing or something like that, you might want to use a camp stove or grill outside the tank so that the flames don’t get close enough to set off any alarms or blow out windows nearby.

In both cases, it’s essential that whatever heat source you use doesn’t melt or damage anything inside the tank itself, including any plastic parts like valves or pipes. So make sure whatever device has been chosen is strong enough to withstand high temperatures and capable of showing no signs of damage after being used at maximum capacity for an extended period without problems. 

Additionally, a propane tank will withstand the heat of direct sunlight to a certain extent. The temperature range of a propane tank is between 100°F and 350°F. In other words, a propane tank can be exposed to direct sunlight for about an hour before it becomes damaged. However, if you let your tank sit out in the sun without storing it properly (such as by leaving it wrapped with its valve open), you risk damaging your tank.

On the other hand, if you let your tank sit in direct sunlight for several hours at a time, such as at a beach where there are no trees to shade it from the sun, then yes—you will probably start seeing damage to your tank after about five or six hours.


 Propane tanks are often used in small camping stoves and can be found at home improvements. They are made of different materials, such as steel and aluminum, and they are all under constant pressure, which can lead to catastrophic consequences if not handled properly. However, Can Propane Tanks Explode in the sun?

The propane tank is typically stored indoors and has a built-in safety mechanism that prevents the gas from escaping if it becomes too pressurized. When properly charged, a propane tank is stable and safe. However, when the tank loses pressure, pressure can build up quickly.
