Ground Double Wall Diesel Tank Inspection Protocol
DAILY CHECKS
Visual Exterior Inspection
Examine exterior for physical damage or corrosion
Check for leaks or pooling fluids around base
Verify all gauges, valves, and caps are secure
Confirm containment area is clean and dry
WEEKLY INSPECTION
System-Level Verification
Inspect interstitial space (between walls) for leaks
Ensure vent pipes are clear and unobstructed
Test pressure relief valves for proper operation
Check fuel for water contamination or sediment
Monthly Equipment Review
- Inspect all hoses and fittings for wear/deterioration
- Test dispensing equipment for proper operation
- Verify leak detection system functionality
- Check alarms and gauges for accuracy
- Inspect secondary containment integrity
- Review inspection records for completeness
Annual Professional Audit
Ultrasonic/hydrostatic tests of double walls, corrosion assessment, and regulatory compliance validation by certified inspectors.
Event-Triggered Inspections
Required after extreme weather (storms, freezing) or physical impacts to assess structural integrity.
Important: Any signs of leakage, structural damage, or system malfunction require immediate shutdown and professional evaluation.
Following this comprehensive schedule—daily visuals, weekly system checks, monthly equipment reviews, and annual professional audits—ensures early problem detection and extends the tank's operational lifespan while maintaining safety compliance.
