Choose the Correct Propane Containers

It is important to be familiar with the type of propane container or containers you own or use. Cylinders and tanks are two different classes of containers. 

• Cylinders are designed to be easily portable and used without permanent mounting, like those for barbecues, R.V.’s and forklifts. 
• Tanks are generally larger and are designed to be more stationary, like the tanks outside homes and businesses or at gas stations.

In many applications, such as on construction sites for example, the cylinders can be as large as tanks, but the rules for storing, transporting and securing the different types of containers vary, so always rely on your propane service provider for direction.

Horizontal Versus Vertical Cylinders

All portable propane cylinders are not alike. Installing the incorrect cylinder could allow propane liquid to enter the piping system, causing your appliances to malfunction and creating a fire and explosion hazard.

Most propane cylinders are vertical (upright) style with the vapour withdrawal valve mounted on the top. These are the type of cylinders you also see in cylinder exchange programs across Canada. Some propane cylinders are designed to be mounted in a horizontal position.

In either case, the cylinder must be used and stored in the position for which it was designed to ensure that the pressure relieve valve is in the vapour space and will activate correctly if the cylinder has been overfilled or is exposed to excessive heat. 

• Never place a cylinder that has been designed for vertical use on its side. 
• Never place a cylinder that has been designed for horizontal use in a vertical position.
• Forklift cylinders are designed to be installed in a horizontal position and stored in a vertical position.  

When you purchase a new cylinder, be sure it fits the bracket you have for your barbecue or appliance, and be sure the cylinder valve connection is compatible with the connection type on your barbecue or appliance.

If you use a cylinder exchange service, be sure the cylinder you receive is the same type you turned in. A propane supplier can confirm that you are using the right type of container.

Older Model Valves

In older model cylinders, the cylinder valves have a left-hand (counter-clockwise) thread for connecting the hose from the appliance, unlike newer models which have a clockwise thread.

Some of the fittings for the older model valves have a rubber “O” ring that requires replacement over time. If your fitting has a rubber “O” ring, check it every time you connect the cylinder, and replace it if it has lost its shape, or is torn, cracked or disintegrating.

Underground Tanks

In some jurisdictions in Canada, underground tanks are used to store propane for a home propane system. Contact your propane supplier to see if underground tanks are available in your area and for details.

A Tip About Colour

The most protective paint colours for the outside of your container are light-coloured, heat reflective choices (normally white). A good paint job will help protect against rust and corrosion and the reflective colour will reduce the increased pressure as temperatures rise, which can lead to a possible discharge from the pressure release valve.
