In what position should a propane container be transported?

The correct approach for transporting a propane container is to ensure that the pressure relief valve remains in the vapor space of the container. This is crucial because the pressure relief valve is designed to release pressure in case it exceeds safe limits, preventing dangerous situations such as explosions or leaks.

When the valve is located in the vapor space, it can effectively manage the pressure by releasing excess gas, which is essential for maintaining the integrity of the container. If the container were to be placed on its side or upside down, the pressure relief valve may be submerged in liquid propane rather than in the vapor space. This would impair its function, posing safety risks.

Additionally, transporting a propane container in an upright position with the pressure relief valve at the top is important, but it does not address the specific requirement of keeping the relief valve in the vapor space. Thus, ensuring that it is in a position allowing the valve to interface with the vapor phase is paramount for safe transportation.
