Which parts are included in the exterior inspection of a water storage tank?

• A. Exterior of the tank, supporting structure, vents, and foundation.
• B. Interior walls
• C. Piping inside the tank only
• D. Electrical panels

Answer: (A)

Exterior inspection focuses on what is visible from the outside and how the tank is supported and anchored. You’d assess the outer surface of the tank for corrosion, dents, or coating failures; check the supporting structure for rust, cracks, misalignment, or instability; verify the vent system is clear, intact, and properly sealed; and inspect the foundation for signs of settlement, cracks, or movement around the base and anchor points. Interior walls, piping inside the tank, and electrical panels aren’t part of this exterior check—they pertain to interior or electrical/system safety inspections rather than the tank’s exterior.
