Which of the following sets lists the three common causes of container stress?

Containers experience stress when what they’re exposed to pushes them beyond what they were designed to handle. The three most common stressors are heat, chemical attack, and physical forces. Thermal stress comes from exposure to high or low temperatures, causing materials to expand or contract, weakening seals, embrittling metals, or degrading liners. Chemical stress happens when contents are corrosive or reactive with the container material or its lining, leading to thinning, pitting, or loss of integrity. Mechanical stress results from external forces like impacts, drops, vibrations, stacking, or punctures, which can deform or rupture the container. Internal pressure is related to these processes and is typically considered a result of thermal or chemical effects, so it’s usually encompassed under mechanical stress in hazmat contexts. Therefore, Thermal, Chemical, and Mechanical cover the main ways a container can be stressed.
