Which of the following gases is typically transported in a pressure cargo tanker?

Transporting gases in a pressure cargo tanker is a common practice and essential for ensuring safety and efficient delivery. Both propane and chlorine are gases that can be transported this way due to their properties and usage.

Propane is a flammable hydrocarbon gas stored under pressure, which allows it to be transported in liquid form. When transported in a cargo tanker, maintaining pressure keeps propane in the liquid state, minimizing its space requirement and reducing the risk associated with flammability when handled appropriately.

Chlorine, on the other hand, is a toxic gas that is also transported under pressure. Chlorine is often stored as a gas but can be liquefied under high pressures, allowing for its safe transport in specialized tankers designed to handle hazardous materials. This method effectively manages the risks of leakage and ensures containment during transit.

Transporting both of these gases in pressure cargo tankers adheres to safety regulations and standards that govern the movement of hazardous materials. The correct response acknowledges that both gases can be safely and effectively moved using this specific type of tanker, thereby confirming the suitability of pressure cargo tankers for transporting these potentially hazardous substances.
