What is the minimum clearance under an outside oil tank to any surface?

The minimum clearance under an outside oil tank to any surface is specified to be 4 inches. This requirement is established to ensure proper ventilation and to prevent moisture accumulation, which can lead to corrosion or other issues with the tank and surrounding area. Adequate clearance is critical for maintaining the integrity of the tank and minimizing the risk of environmental contamination.

Moreover, this clearance facilitates access for inspection and maintenance activities, ensuring that technicians can safely work on the tank and surrounding components. Following this guideline is essential to comply with safety regulations and best practices in fuel storage management.
