Which type of intermodal tank typically carries nonregulated materials?

Intermodal tanks are specialized containers designed for the transportation of various materials, including hazardous and nonregulated substances. The choice of IM 102 intermodal portable tanks is correct because these tanks are specifically designed to carry nonregulated materials. They have a maximum allowable pressure of 100 kPa (15 psi) and can hold liquids and solids that are not classified as dangerous under transportation regulations.

IM 102 tanks are typically used for materials such as food-grade and agricultural products, which do not pose the same risks as regulated hazardous materials. This makes them suitable for applications where stricter hazardous material regulations do not apply.

In contrast, IM 101 portable tanks are intended for regulated materials, including some hazardous substances, while IM 103 and IM 104 tanks are built for the transportation of materials with specific risks associated with them. Both of these options have design features suited to handling certain classifications of hazardous materials, thus distinguishing them from the IM 102 tanks that cater to nonregulated content.
