To maintain safe fuel storage, what must be regularly checked?

Regularly checking the structural integrity of fuel storage tanks is essential in maintaining safe fuel storage. This practice ensures that the tanks remain intact and free from leaks or structural failures that could lead to contamination, environmental hazards, or safety incidents. Over time, tanks can experience corrosion, material fatigue, or damage due to external factors. Ensuring that the tanks are structurally sound helps mitigate risks associated with fuel spills, which can have significant environmental and safety implications.

While the other aspects such as soil conditions, ambient air quality, and external temperature can influence fuel storage safety, they are not as directly linked to the integrity of the fuel storage infrastructure. Soil conditions may affect tank installation or underground tanks but do not directly address the condition of the tanks themselves. Ambient air quality and external temperature may impact operational procedures but do not relate to the physical condition and safety of the tanks in direct ways as structural integrity does. Therefore, prioritizing the structural health of the tanks is key in ensuring safe fuel storage operations.
