When it comes to using propane tanks, you want to make sure that you are deploying them according to the orientation recommended for that specific tank.
Some tanks can be tipped on their side and used horizontally (especially tanks made to be used that way), but when it comes to flipping tanks intended to be used vertically to the side you can run into a whole host of safety issues.
It’s generally not advised.
To learn a little more about what we’re talking about, let’s jump into the rest of this quick guide.
The Design and Function of Vertical and Horizontal Propane Tanks
Vertical and horizontal propane tanks are designed differently to accommodate the different positions in which they are used.
Vertical propane tanks are cylindrical in shape and are designed to be used in a standing position, with the valve and fittings located at the top of the tank.
These tanks are typically used for stationary applications, such as providing fuel for a home heating system or powering outdoor appliances.
Horizontal propane tanks are also cylindrical, but they are designed to be used in a horizontal position, with the valve and fittings located at one end of the tank.
These tanks are often used in portable applications, such as powering outdoor grills or providing fuel for recreational vehicles.
The main difference between vertical and horizontal propane tanks is the position in which they are used and the location of the valve and fittings.
It is important to use propane tanks in the position they are designed for, as using them in an improper position could cause safety issues or prevent them from functioning properly.
The Safety and Legal Implications of Using a Vertical Propane Tank Horizontally
You can run into a whole mess of problems when you flip a propane tank designed to be used vertically on its side, including (but definitely not limited to):
- Access to the valve and fittings may be blocked: When a propane tank is used in a horizontal position, the liquid propane inside the tank can block the valve and fittings, making it difficult or impossible to access them. This can prevent the tank from functioning properly and may cause safety issues.
- Leaks may occur: Using a propane tank in an improper position can increase the risk of leaks or other types of damage to the tank. This can be dangerous, as propane is a flammable gas that can ignite if it comes into contact with an open flame or spark.
- Safety devices may not function properly: Propane tanks are equipped with safety devices, such as relief valves and excess flow valves, that are designed to protect against overpressure and leaks. These devices may not function properly if the tank is used in an improper position.
In terms of legal risks, using a propane tank in an improper position may violate local laws or regulations governing the use of propane. Depending on the jurisdiction, this could result in fines or other penalties.
The governing bodies responsible for propane safety vary by country and region. In the United States, the National Propane Gas Association (NPGA) is a national trade association that works to promote the safe and efficient use of propane.
The NPGA develops codes and standards for the propane industry and provides resources and training to help ensure the safe handling and use of propane.
On top of the NPGA, the U.S. Department of Transportation (DOT) has regulatory authority over the transportation of propane, while the Occupational Safety and Health Administration (OSHA) sets safety standards for the handling and use of propane in the workplace.
You certainly don’t want to be running crosswise of the folks at OSHA when it comes to improperly using propane systems, that’s for sure.
Methods for Using a Vertical Propane Tank Horizontally
Before we get into how you could – could – use a vertical propane tank in the horizontal position, remember that this is not advices.
This isn’t something you’re going to want to do a whole lot (if at all, unless very necessary in the short term).
If you absolutely need to use a propane tank in a horizontal position, you should consult the manufacturer or a certified propane professional to determine whether it is safe to do so and to obtain any necessary modifications or precautions.
Some possible options for using a vertical propane tank in a horizontal position safely may include:
- Modifying the tank: If you need to use a propane tank in a horizontal position, you may be able to have the tank modified by a certified professional to make it suitable for use in this position. This could involve adding additional fittings or valves or making other modifications to the tank.
- Using an adapter: An adapter may be available that allows you to connect a vertical propane tank to a horizontal appliance. This could allow you to use the tank in a horizontal position without modifying the tank itself.
- Using a different type of tank: If you need to use a propane tank in a horizontal position, you may be able to use a horizontal propane tank instead. These tanks are specifically designed for use in a horizontal position and may be a safer option than using a vertical tank in a horizontal position.
Considerations for Using a Vertical Propane Tank Horizontally
Don’t just jump right into flipping a vertical propane tank on its side, either.
There are a couple of things you need to be thinking about before you do this, such as:
- Safety: Using a propane tank in an improper position can increase the risk of leaks or other safety issues. You should consult the manufacturer or a certified propane professional to determine whether it is safe to use a vertical propane tank in a horizontal position and to obtain any necessary modifications or precautions.
- Access to the valve and fittings: When a propane tank is used in a horizontal position, the liquid propane inside the tank can block the valve and fittings, making it difficult or impossible to access them. This can prevent the tank from functioning properly and may cause safety issues.
- Compatibility with the application: You should ensure that the hardware you are using the propane tank with is compatible with the tank and can be safely connected in a horizontal position.
- Local laws and regulations: Using a propane tank in an improper position may violate local laws or regulations governing the use of propane. You should familiarize yourself with these laws and regulations and ensure that you are complying with them.
- Proper handling and storage: When using a propane tank, it is important to handle and store it properly to reduce the risk of accidents or injuries. This includes following proper handling and storage procedures and taking precautions to prevent damage to the tank.
Alternatives to Using a Vertical Propane Tank Horizontally
There are several alternatives to using a vertical propane tank in a horizontal position:
- Use a horizontal propane tank: If you need to use a propane tank in a horizontal position, you may be able to use a horizontal propane tank instead. These tanks are specifically designed for use in a horizontal position and may be a safer option than using a vertical tank in a horizontal position.
- Modify the appliance: If you are using a propane tank with an appliance that is not compatible with a vertical tank, you may be able to modify the appliance to allow it to be used with a vertical tank.
- Use a different fuel source: Depending on the appliance you are using, you may be able to use a different fuel source, such as natural gas or electricity, instead of propane.
- Use a portable propane tank: If you need a portable fuel source, you may be able to use a small, portable propane tank that is designed for use in a horizontal position. These tanks are often used with outdoor grills and other portable appliances.
Final Thoughts
If you can, as much as possible, really try to avoid using a propane tank designed for vertically applications on its side.
These tanks just aren’t intended for that kind of application and you run a ton of safety risks when you ignore this reality. We’re not talking about minor accidents waiting to happen, either.
We mean accidents that can prove to be life changing – if not life ending.
Should you absolutely need to use a vertical tank in the horizontal position, though, be sure to keep everything we highlighted above in mind. Be quick, be safe, and hunt for alternatives before you go down this road.
