Final answer:
Compressed gas containers should not be exposed to temperatures exceeding or below the mean atmospheric temperatures unless designed for those conditions, to prevent pressure-induced risks.
Step-by-step explanation:
The requirement for compressed gas containers in relation to temperature exposure is that they should not be exposed to temperatures exceeding or below the mean low atmospheric temperatures unless they are specifically designed to be used under those conditions. This means that compressed gas containers should be protected from extreme temperatures to prevent the risk of explosion or structural failure due to pressure changes within the container. As temperature affects the pressure inside the container, it is critical to follow the specified temperature guidelines for safe storage and use.
