What is the function of a "cargo tank"?

A cargo tank serves as a specialized tank designed specifically for the transportation of liquids or gases in bulk. These tanks are typically mounted on vehicles, such as trucks or railcars, allowing for efficient and secure transport of various substances, including hazardous materials.

Cargo tanks are constructed to meet stringent regulatory standards that ensure the safety and integrity of the materials being transported, thereby minimizing the risk of spills or leaks during transit. This makes them essential for industries that require the movement of large quantities of liquids or gases, providing a solution that is both practical and compliant with safety regulations.

In contrast, the other options do not accurately describe the function of a cargo tank. For example, a container for solid waste pertains to a different type of storage solution, while a separate storage facility for hazardous waste would be designated for holding materials rather than transporting them. Additionally, lightweight packaging refers to packaging typically used for smaller quantities and different types of materials rather than bulk transport solutions.
