What must underground and mounded containers be protected against?

Underground and mounded LP gas containers must be protected against corrosion because they are often in contact with soil and moisture, which can lead to deterioration over time. Corrosion can compromise the structural integrity of the container, potentially leading to leaks or failures that can create hazardous situations. To prevent this, various protective measures such as coatings, cathodic protection systems, or using materials resistant to corrosion are often implemented.

While factors like UV radiation, earthquakes, and fuel leaks are significant in their own contexts, they do not pertain specifically to the primary concern regarding underground and mounded containers. UV radiation applies more to above-ground installations where sunlight exposure can degrade materials. Earthquakes are a consideration for all structures but specifically relate more to seismic safety than to your primary concern of corrosion. Fuel leaks are an outcome of improper handling or maintenance rather than a condition to shield against in the context of underground and mounded container installation.
