Ben Hirst Hazardous Materials Awareness and Operations Practice Exam

IM-101 intermodal portable tanks are designed for transporting liquids, specifically flammable liquids (Class 3). They are non-pressurized containers used in intermodal movements across rail, truck, and ship, and they’re chosen for liquids that have flash points and hazards typical of flammable fuels and solvents. Hydrogen, being a gas at ambient conditions, requires a pressurized gas vessel rather than an IM-101 tank. Radioactive materials need specialized shielding and packaging types, not standard intermodal tanks like IM-101. Nonregulated materials don’t require these specialized tanks at all. So the category most commonly associated with IM-101 is flammable liquids.
