Risks Of Leaving A Propane Tank On After Grilling

There are many risks associated with leaving on a propane tank after you are done using it. Some of these can result in severe injury, while others can be fatal. So it is very important to always turn off your propane tank after grilling. 

It Can Be A Fire Hazard

A propane tank left on after grilling can become a fire hazard if it is knocked over or if the valve is left open. Imagine if there is someone smoking a cigarette nearby. A small spark is enough to ignite the liquid petroleum gas, and that will always result in an explosion. This can destroy your property and injure you and your family members.

Carbon Monoxide Poisoning

Propane gas can release carbon monoxide, which is an odorless and colorless gas that can be deadly if inhaled in large amounts. If a propane tank is left on in an enclosed space such as a garage or shed, it can lead to a buildup of carbon monoxide and increase the risk of poisoning. 

It Can Result In Loss Of Money

In this time of high financial uncertainty, it is very important to save money wherever you can. However, leaving the LPG tank open when you are not grilling anything means letting the gas leak. This is not just dangerous, but it will also result in loss of gas that you could have used in your next grilling experience.

So if you have lost all the gas in the propane tank, you will have to get the tank filled once again the next time you think about arranging a BBQ, and that will cost you additional money. 

Gas Leak

Leaving a propane tank on can also result in a gas leak which can be dangerous as propane is highly flammable. A gas leak can occur if the valve is not properly closed or if the tank is damaged.


Propane tanks can rust over time, especially if exposed to moisture or other environmental factors. Leaving the tank on can accelerate this process and increase the risk of a leak or other damage.

Rust and corrosion can wither off the outer layer of the LPG tank, causing the liquid petroleum gas inside to leak. Even if the tank is empty and you are not worried about the gas leak, you still have to be careful not to use it at your next grilling event.

It Can Be Risky For Children

When you are having a family barbeque, you are bound to have some kids over. Leaving a propane tank on after grilling can also increase the risk of unauthorized use. If someone else, such as a child or unauthorized person, gains access to the grill and the tank is left on, they could accidentally or intentionally cause harm to themselves or others. It is important to always turn off the tank after use and keep it in a secure location to prevent unauthorized access.

Increased Pressure Inside the Cylinder 

When a propane tank is left on, the pressure inside the tank can increase, causing it to become unstable and potentially dangerous for the things and people in its surroundings.

To avoid these risks, it is important to always turn off the propane cylinder after grilling and store it safely away from heat sources, flames, or other hazards. Additionally, it is a good practice to inspect your propane tank regularly for any signs of damage or wear and to replace it if necessary.

Storing your propane tank properly is as important as turning off the propane tank after use. It can still be hazardous if you don’t store it properly. As mentioned above, it can result in corrosion and gas leaks and may also increase the iteral pressure inside the tank. 

Here are some steps to follow when storing your propane tank

Turn off the Gas Valve

This is one of the first steps and the most basic steps that you need to take. Make sure to turn off the gas valve on the propane container. This will prevent any gas from escaping and reduce the risk of a gas leak.

Disconnect the Tank

Disconnect the propane tank from the grill by unscrewing it from the regulator. Be careful not to damage any of the connections in the process. Make sure both the propane tank and the grill knobs are turned off before you start unscrewing. 

Check for Damages 

Inspect the tank for any signs of damage, such as dents or corrosion. If the tank is damaged, do not use it and dispose of it properly. Even if you don’t feel any leaks right away, a damaged LPG tank can get worse over time, and it can become leaky. So it is very important to get rid of the propane tank that is dented. 

Store in a Safe Location

Store the propane tank in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Propane tanks should be kept outside and not stored indoors as they can release gas and create a fire hazard. Additionally, they should be kept away from flammable materials and sources of ignition.

Final Thoughts

It is highly recommended to turn off your gas tank after you are done with the grilling. Not only does it ensure safety by preventing gas leaks or fire hazards, but it also helps to conserve propane and save money in the long run. Leaving the tank valve open can cause the liquid petroleum gas to escape slowly over time leading to waste and unnecessary expenses. 

Therefore it is always better to take a few extra minutes to turn off the propane tank after grilling and enjoy your meal with peace of mind. Remember to follow proper safety precautions and consult the manufacturer's instructions for your specific grill model.
