Crude Oil Storage Tank Inspection Checklist [FREE PDF]

Crude oil storage tanks are subject to strict federal and industry regulations including OSHA 29 CFR 1910.119 Process Safety Management, EPA 40 CFR Part 112 Spill Prevention Control and Countermeasure (SPCC), and NFPA 30 Flammable and Combustible Liquids Code. Regular inspections are essential to prevent catastrophic releases, fires, and environmental contamination. This checklist aligns with API Standard 653 Tank Inspection, Repair, Alteration, and Reconstruction requirements to ensure structur

Industry: Oil & Gas
Frequency: Monthly
Estimated Time: 45-60 minutes
Role: Production Operator
Total Items: 42
Compliance: OSHA 29 CFR 1910.119 Process Safety Management, EPA 40 CFR Part 112 SPCC, NFPA 30 Flammable and Combustible Liquids Code, API Standard 653 Tank Inspection, API RP 575 Inspection of Atmospheric and Low-Pressure Storage Tanks

Shell & Structural Integrity

Assess external condition of tank shell, roof, and foundation for signs of deterioration or failure.

Is the tank shell free of visible corrosion, pitting, or wall thinning?
Is the tank roof (floating or fixed) free of structural damage, tears, or deformation?
Is the tank foundation and base plate area free of settlement, erosion, or undermining?
Are all shell nozzles, manholes, and connections free of leaks or visible damage?
Are any weld seams showing signs of cracking or separation?
Provide notes on any observed structural defects or anomalies.

Secondary Containment & Dike Integrity

Verify that secondary containment systems are functional and meet regulatory capacity requirements.

Does the secondary containment dike hold the required volume (110% of largest tank)?
Is the dike free of cracks, erosion, or breaches that could compromise containment?
Are dike drainage valves in the closed/locked position when not in use?
Is the containment area free of accumulated liquid, debris, or vegetation that could impair function?
Are containment liner or impermeable surfaces in good condition with no visible perforations?

Venting & Pressure Relief Systems

Inspect all tank vents, pressure-vacuum valves, and emergency relief devices for proper operation.

Are all normal vents (breather valves) free of blockage, corrosion, or ice buildup?
Are emergency pressure/vacuum relief vents operational and set to design specifications?
Are flame arrestors installed and free of plugging or damage?
Are all vent openings facing away from ignition sources and positioned per design?
What is the last recorded relief valve test date?

Floating Roof & Seal Condition

Evaluate the condition of floating roof components, seals, and drainage systems.

Is the primary seal between the floating roof and tank shell intact and undamaged?
Is the secondary seal free of tears, gaps, or liquid accumulation above the roof?
Are the roof drain lines and sump free of blockage and operating properly?
Are roof support legs in good condition and correctly positioned?
Is the roof level (not tilted or listing) when observed from the tank top?

Instrumentation & Level Gauging

Check tank level gauges, alarms, and monitoring instrumentation for accuracy and function.

Is the primary level gauge (manual or automatic) reading accurately and in good condition?
Is the high-level alarm set point calibrated and tested within the required interval?
Is the high-high level shutdown (overfill protection) device functional and tested?
Are temperature sensors and gauges operational and reading within expected range?
Current product temperature reading (°F)?

Fire Safety & Suppression Systems

Verify fire detection, suppression, and emergency response equipment around the tank.

Is the foam suppression system (if installed) in operable condition with adequate foam supply?
Are fire detection sensors (heat or flame detectors) functional and tested within 12 months?
Are portable fire extinguishers present, fully charged, and within inspection date?
Are emergency access roads and egress paths around the tank clear and unobstructed?
Are 'No Smoking' and hazard warning signs posted and legible at all tank access points?

Electrical Grounding & Bonding

Inspect static grounding and bonding systems to prevent electrostatic ignition hazards.

Is the tank shell properly grounded with resistance verified within the last 12 months?
Are all grounding cables and clamps free of corrosion, breakage, or loose connections?
Are lightning protection systems (rods, cables, surge arrestors) intact and undamaged?
Are electrical classification (Class I, Div 1/2) boundaries maintained with no unapproved equipment?
Record measured grounding resistance value (ohms) if tested during this inspection.

Housekeeping & Documentation Review

Review tank area housekeeping conditions and verify required documentation is current.

Is the tank area free of oil spills, drips, or product accumulation on the ground?
Is the current SPCC plan available on-site and up-to-date for this tank?
Are previous inspection records and mechanical integrity logs accessible and current?
Are all corrective actions from the previous inspection closed out?
Attach photo documentation of any deficiencies found during this inspection.
Provide overall inspection summary and recommended corrective actions.
