Why is it important for storage cylinders to be on stable foundations?

Storing cylinders on stable foundations is crucial for safety reasons. When storage cylinders are properly secured and on a stable surface, the risk of them tipping or falling over is significantly minimized. This stability is vital, especially considering that compressed natural gas (CNG) is stored at high pressures. If a cylinder were to tip over, it could create a hazardous situation, potentially resulting in leaks or dangerous gas releases, as well as posing a risk of physical damage or injury. Therefore, ensuring that storage cylinders are placed on stable foundations is an essential safety measure in preventing accidents and maintaining operational integrity. The other options address lesser concerns and do not prioritize the critical safety aspects associated with the proper storage of CNG cylinders.
