How must hazardous materials be packaged?

Hazardous materials must be packaged in approved containers that meet specific safety standards to ensure safety during transport and handling. These standards are designed to prevent leaks, spills, or ruptures that could occur during movement, loading, or even routine handling. Approved containers are tested for their ability to withstand various conditions that might occur in transport, such as changes in temperature, pressure variations, and mechanical impacts.

Specialized packaging regulations also take into account the nature of the hazardous material itself, requiring that materials be contained in ways that mitigate risks related to fire, corrosion, or toxicity. For example, toxic substances may need to be packaged in double-walled containers to ensure that if the outer layer is compromised, the inner layer still provides a barrier.

In contrast, the other options, such as cardboard boxes, plastic bags, or metal barrels, do not necessarily comply with the stringent regulations required for transporting hazardous materials unless they have been specifically tested and approved for that purpose. This distinction is crucial for ensuring public safety and preventing environmental hazards associated with hazardous materials transportation.
