How should new propane cylinders be transported according to the guidelines?

The safest and most appropriate way to transport new propane cylinders is by ensuring that they have never contained propane. Transporting cylinders that have never held propane inside a vehicle minimizes the risk of leaks or explosions associated with flammable gases. This practice aligns with safety regulations designed to protect the transporters and the public from potential hazards.

Transporting cylinders outside of the vehicle is often preferred, particularly for those that have previously contained propane, due to the increased risk of leaks from older tanks. Mounting cylinders on the roof is not a standard or safe practice and could lead to dangerous situations, such as falling or being subject to improper handling or environmental exposure. Thus, knowing the condition of the cylinder is crucial for safe transport, making it essential for anyone handling propane to adhere strictly to these regulations.
