[Safety facts] Can Propane Tanks Explode in the Sun?

Yes, propane tanks can explode in the sun. But it depends on how long you have kept the tanks in the sun. If you keep the tanks outside in the sun for a long time, the temperature of the tanks will increase, and the pressure inside will also increase. So, there is a chance of exploding the tanks.

However, we use these tanks for cooking and other day-to-day tasks. Often we use these tanks outside also. But you might not know that keeping these tanks outside in the sub for a long time is not safe. Moreover, knowing about safety is essential.

Let’s see details about it.

Can Propane Tanks Explode in the Sun?

What temperature causes the propane tank’s explosion?

Temperatures above 120 degrees Fahrenheit or 49 degrees Celsius can cause propane tanks explosion. Generally, this gas tank can withstand very low temperatures or room temperature. When you put this tank outside in the sun, the temperature might not be 49 degrees Celsius at once.

But if you keep the tank outside for a long time, the tanks will easily reach up to the temperature. So, keeping these tanks outside is risky. Moreover, it is unpredictable before the tank explodes. So, you must keep safe while using these tanks.

Why do propane tanks explode at high temperatures?

When the propane tanks get high temperatures, they can explode. Because after getting a high temperature, the tank’s body gets hotter. So, the pressure inside the tank increases. The more the temperature, the high the pressure rises.

So, when the tank gets excessive pressure, the tank can’t hold it anymore. So, an explosion occurs. That’s how high temperatures can explode the tanks.

Can you keep propane tanks in the garage?

No, you can’t keep propane tanks in the garage. Generally, these tanks should be stored in a shaded and ventilated place. But the garage doesn’t have much ventilation. Moreover, the garage is generally a confined area.

Gas and gas tanks should not be kept in a confined area. While keeping these tanks, ventilation is a must. Besides, the garage might have a high temperature being a confined area. This issue is also not suitable for keeping these tanks in the garage.

Is propane gas flammable?

Yes, propane gas is highly flammable. That means catching on fire is easy for this gas. Moreover, this gas can catch on fire at a lower or medium temperature. Besides, this gas can readily create an explosive mixture with air.

So, you must be careful about keeping propane tanks. Once the gas is leaked, it can become highly dangerous.

Is it possible to explode propane tanks in cold weather?

No, propane tanks can’t explode from cold. When you keep these tanks outside at a freezing temperature, the gas will freeze. You might know that liquid gas is stored in tanks. That liquid gas will freeze.

But there is no chance of exploding the tanks. One problem might arise if the gas freezes. You have to wait until the frozen gas is not liquid again.

Where can you store propane tanks?

Now that you know you should not keep propane tanks outside in the sun, you might want to know where you can store them. You can store these tanks in a shaded area. That doesn’t mean that you have to keep these tanks in a confined area.

A confined area can also be risky for these tanks. So, ventilation should also be there. So, you can keep these tanks stored in a shaded and ventilated place. 

Can you keep propane tanks inside your house?

Generally, you can keep these tanks inside the house if there is enough ventilation. But you should not keep these tanks inside your house for safety purposes. Propane tanks can explode from high temperatures and pressure.

So, you can’t always know the situation of these tanks inside the house. Moreover, you can’t see any symptoms of exploding the tanks. That’s why these tanks should be kept far away from your house.

What is the use of the gas valve of propane tanks?

Propane tanks have gas valves on them. These valves are for safety so that the tanks don’t leak gases. Generally, propane is difficult to detect since it is odorless. So, you might not know if the tanks have leakage or gas leaks from the gas valve.

So, you must shut the gas valve after every use. Otherwise, the open gas valve can be risky.

Can you leave a propane tank in the car?

You should never leave a propane tank in the car when all the windows are closed. Generally, before starting the car, the temperature of the engine and inside parts are not too high. But when you drive the car and leave it in a place for parking, you should not close all the windows.

Because after driving a long way, the engine and inside parts of the car are at high temperatures. A closed window will also not allow ventilation. So, the pressure of the tank will rise and can cause an explosion.

What are propane tanks made of?

Generally, the body parts of the propane tanks are made of steel. Sometimes, aluminum and composites are also used to make the tanks. Now that you know these tanks can get extremely hot at high temperatures, you might want to know how.

Generally, the tanks’ steel, aluminum, and composites are all heat-conductive materials. So, the more temperature they get, the hotter they become.

1. Can small propane tanks explode in the sun?

Generally, the size of the propane tanks doesn’t matter. If the tanks get extremely hot and the pressure inside increases, the tanks can explode. So, if you put small tanks in the sun for a long time, there is a chance of explosion.

What are the common causes of propane tanks’ explosions?

An open bleeder valve in the propane tanks can cause an explosion. Moreover, fire can cause the tanks to be explosive. If the temperature of the tanks is extremely high, the tanks can explode. These are some common reasons for tanks’ explosions.

Can you leave a propane tank outside in the summer?

No, you should not leave a propane tank outside in the summer. In the summer, the outside temperature is excessively high. So, it can raise the tank’s temperature and inside pressure. For these reasons, an explosion can occur.
