Aboveground storage tanks play an important role in agricultural and industrial operations, storing everything from fuel and chemicals to water and other essential liquids. While these tanks are built for durability, regular inspections are necessary to identify potential problems before they lead to leaks, equipment damage, environmental concerns, or costly downtime.
A monthly Aboveground Storage Tank Inspection helps facility managers and maintenance teams stay ahead of developing issues while protecting employees, equipment, and surrounding property.
Why Monthly Tank Inspections Matter
Storage tanks are constantly exposed to changing temperatures, weather conditions, and operational demands. Over time, corrosion, worn seals, damaged fittings, and structural deterioration can compromise tank integrity.
Routine inspections help identify warning signs early, allowing maintenance teams to address problems before they become more serious.
Monthly visual inspections can also support broader maintenance programs and help facilities maintain accurate records of tank conditions.
Inspection frequency and specific requirements may vary depending on the tank’s contents, construction, location, and applicable regulations.
1. Inspect the Tank Exterior
Begin by examining the tank’s exterior for visible signs of damage or deterioration.
Look for:
- Rust, corrosion, or peeling protective coatings
- Dents, cracks, or unusual deformation
- Leaks around seams, welds, or connections
- Discoloration or staining
- Signs of settlement or shifting
Any unusual condition should be documented and evaluated before it becomes a larger problem.
2. Check Valves, Fittings, and Connections
Valves and connections are common locations for leaks.
Inspect accessible components for signs of corrosion, damaged seals, loose connections, and visible leakage. Make sure valves are properly identified and accessible.
Do not attempt to tighten, disconnect, or repair components containing hazardous materials without following approved procedures.
3. Examine the Tank Foundation and Supports
A tank’s structural stability depends on the condition of its foundation.
Check for cracks, erosion, uneven settlement, damaged supports, or standing water around the tank base.
Foundation problems can create additional stress on the tank and connected piping.
4. Inspect Secondary Containment
Secondary containment helps prevent spilled or leaked materials from spreading beyond the storage area.
During an Aboveground Storage Tank Inspection, check containment walls, floors, liners, and drainage systems for visible damage.
Remove accumulated rainwater only according to approved facility procedures, after confirming it is not contaminated.
5. Check Vents and Safety Equipment
Properly functioning vents and protective devices are important for safe tank operation.
Inspect accessible vent openings for visible obstructions, corrosion, or damage. Verify that emergency equipment, warning labels, and other safety components remain accessible and in good condition.
Testing or servicing pressure relief devices should be performed by qualified personnel according to applicable requirements.
6. Look for Signs of Leaks or Spills
Walk around the tank and surrounding area to identify unusual odors, stains, wet spots, or pooled liquids.
Check nearby piping and transfer areas as well.
Any suspected release should be reported immediately and handled according to the facility’s spill response procedures.
7. Document Findings and Corrective Actions
An inspection is only valuable when identified problems lead to action.
Record the inspection date, tank identification, observations, and any maintenance needed. Assign responsibility for corrective actions and track them until completion.
Consistent documentation also helps identify recurring issues and changes in tank condition over time.
