What type of damage does the 'stress' phase of a container undergo?

The 'stress' phase of a container primarily involves physical or thermal damage. During this phase, containers can experience physical forces that may cause deformation or cracks due to external pressure, impact, or overpressurization. In addition, thermal stress can occur when there is a significant temperature difference across the container materials, leading to expansion or contraction. This can weaken the structural integrity of the container, making it more susceptible to leaks or failure.

In practice, understanding this phase is critical for responders dealing with hazardous materials, as recognizing the signs of stress can help in assessing the risk of a container breach and determining the appropriate response measures. By identifying that the damage is primarily physical or thermal, responders can make informed decisions to mitigate potential hazards effectively.
