When inspecting an oil storage tank, what should be checked for leaks?

When inspecting an oil storage tank for leaks, examining the base and seams is essential. These areas are particularly vulnerable to leaks due to the potential for corrosion, structural stress, or damage from external factors. The base is where the tank makes contact with the ground, and any deterioration or issues in this area can lead to leaks. The seams, where different sections of the tank are joined, are also critical points for inspection because they can be weak points that may develop cracks or gaps over time.

While it is important to conduct a visual inspection of the lid to ensure it is sealed properly and to check all pipes connected to the tank, these areas do not cover the critical points where leaks are most likely to occur. Focusing on the structural integrity at the base and seams helps identify potential leaks before they lead to more serious issues, such as environmental contamination or loss of fuel.
