What potential hazard does thermal stress pose to containers?

• A. Changes in chemical composition
• B. Container freezing
• C. Loss of structural integrity
• D. Non-hazardous material release

Answer: (C)

Thermal stress can lead to the loss of structural integrity in containers. When containers are exposed to extreme temperature variations, such as rapid heating or cooling, materials can expand or contract. This can result in physical stresses that compromise the container's ability to withstand internal pressures or external forces. If the structural integrity is compromised, it could lead to leaks, ruptures, or failures that pose significant risks, especially if the container holds hazardous materials.

While the other options might represent concerns in specific circumstances, they do not capture the overarching risk associated with thermal stress in relation to the fundamental integrity of the container itself.
