Storage Tank Maintenance Checklist

This brief guide outlines all the necessary stages in storage tank maintenance, for the safe containment of oil, chemicals, pulp, paper, etc. Regular and thorough tank inspections are critical to proactively identifying and repairing potential problems, which might lead to tank failure and disastrous environmental contamination or workplace injuries.

Tank Inspection and Maintenance

All storage tank inspections must be performed against the approved drawings, specifications, and standards, and according to any applicable legislation.

Inspections are carried out periodically:

• Monthly in-service routine inspections undertaken by the owner’s inspector.
• Annual in-service routine inspections undertaken by the owner’s inspector.
• 5-yearly inspection undertaken by a certified external inspector.

Monthly Tank Maintenance Inspection

Regular storage tank repair and maintenance will extend safe operating life. You can use the following storage tank inspection checklist for routine monthly maintenance:

• If all your answers are “Yes”, your tank is in good condition.
• If any answers are “No”, schedule repairs in the comments section. Welding, grinding, and other hot works require the tank to be taken out of service.

Annual Tank Inspection

These important annual checks supplement the monthly checklist:

5-Year Inspection

T he external inspector examines all the annual inspection items. Structural evaluation tests are conducted, including assessing the condition of the interior and exterior coatings.

The inspection encompasses site restrictions, proximal electric lines, or other structures that could interfere with containment.

Federal U.S. EPA, state-level public health considerations, and OSHA regulations must be considered if the tank requires upgrades. If tank rehabilitation is necessary, checks are conducted to establish if there is sufficient space to stage the necessary equipment.

Why is it Important to Clean and Inspect Tanks?

Scheduled tank inspections and maintenance should be your top priority, to keep your tank in optimal condition. This is essential to:

• Prevent hazards: Cracks, thinning walls, corrosion, or bad welds may cause dangerous leaks and hazardous working conditions. With ongoing inspection and rectification, you’ll maintain your daily production and safeguard your employees.
• Extend the tank’s lifespan: Periodically checking your tank’s status extends its reliability and lifespan. You’ll get the greatest possible return on your investment.
• Comply with standards and regulations: When a fuel tank is regularly checked and maintained against legal and industry standards, your company is protected from liability.

National Fire Protection Association (NFPA) and American Water Works Association (AWWA)

Your tank must be fully compliant with federal, state, and local regulatory requirements. The applicable NFPA and AWWA regulations and inspection frequency are dictated by the type of tank and its contents. For example, is the storage tank underground or above ground? Is it steel or concrete? Does it store hazardous substances? Complete in-service and out-of-service inspections should be completed by certified technicians in accordance with NFPA and AWWA standards.
