Explain what “containerization” refers to in hazardous materials transport.

Containerization in the context of hazardous materials transport specifically refers to the practice of using specialized containers designed to safely transport substances that may pose risks to health, safety, or the environment. These containers are engineered to withstand various physical and chemical stresses, preventing leaks and spills that could occur during handling and transport.

Specialized containers often include features such as reinforced structures, secure closures, and materials resistant to corrosion or degradation by the hazardous substances they contain. This method ensures compliance with safety regulations and standards while minimizing the potential for accidents and environmental contamination.

The other concepts presented do not align with the definition of containerization. Storing hazardous materials in open containers, for instance, would increase the risk of exposure and contamination, while labeling methods focus more on communication of hazards rather than the physical means of transport. Transporting materials without containers contradicts the very principles of safe handling of hazardous materials, as it would lead to a significant increase in the risk of spills and accidental releases.
