Which of the following is true regarding the transportation of propane?

The transportation of propane must be conducted in approved cylinders due to safety and regulatory standards. Approved cylinders are designed specifically to contain liquefied petroleum gases like propane, ensuring they can withstand high pressures and prevent leaks or explosions. These cylinders are built to comply with various safety regulations, including those established by organizations such as the Department of Transportation (DOT) in the United States, which mandates the use of compliant packaging for hazardous materials.

Choosing to use unapproved containers or lacking the appropriate safety measures could lead to serious safety hazards, including leaks, fires, or explosions. Proper transportation practices not only protect those handling the propane but also minimize risks to the public and the environment.
