The correct answer is that only DOT-approved containers are acceptable for transporting LP-gas. The Department of Transportation (DOT) sets stringent safety standards for the transportation of hazardous materials, including liquefied petroleum gas (LP-gas). These standards are mandated to ensure that containers can safely withstand the pressures and potential hazards associated with transporting LP-gas.

DOT-approved containers are designed specifically to accommodate the unique characteristics of LP-gas, including its pressurization and flammability. They are subject to rigorous testing and certification processes to ensure their structural integrity and safety during transit. Using containers that are not DOT-approved could lead to leaks, ruptures, or other hazardous situations that pose risks to both people and the environment.

Open containers, standard plastic containers, or homemade containers do not meet the safety specifications or regulations required for transporting LP-gas. They could easily fail to contain the gas under pressure, leading to leaks or accidents. Therefore, adherence to DOT regulations is crucial for the safe transportation of LP-gas, making DOT-approved containers the only acceptable option.
