Waste Oil Tank Inspection Guide
Essential procedures and standards for maintaining safe and compliant waste oil storage systems
Tank Appearance and Sealing Inspection
Observe the tank surface for corrosion, deformation, cracks, or coating peeling. Focus on key areas such as the tank wall, bottom, end caps, and welds.
Check all sealing interfaces, valves, and flange connections for leaks. Inspect seals for aging or damage.
Ensure valves operate smoothly and seal tightly when closed, with no waste oil dripping or evaporation leakage.
Functional Inspection of Auxiliary Equipment
Verify the accuracy of level gauges and pressure gauges to clearly reflect the tank's internal status.
Check that safety valves, emergency shut-off valves, and other safety devices are in normal standby condition.
Ensure anti-static grounding devices and lightning protection facilities are securely and effectively connected. Confirm that fire extinguishers, oil-absorbing mats, and other emergency supplies are complete and not expired, and that auxiliary pipelines are free from blockages, corrosion, or damage.
Storage Environment and Surrounding Area Management
Check that the waste oil tank storage area is well-ventilated, the ground is dry and level, and there is no standing water or debris.
Confirm that the storage area is far away from fire sources, heat sources, and flammable and explosive materials.
Verify that the seepage prevention layer is undamaged; and that the overflow dike is intact and free of liquid accumulation. Check that surrounding safety warning signs are clear, complete, and unobstructed; and strictly prohibit unauthorized personnel from approaching or conducting unauthorized operations in the vicinity.
Compliance Records and Maintenance Verification
Verify that daily inspection logs are filled out in a timely manner, and that the records are complete and standardized.
Key verification points:
- Records cover inspection time, conditions, and problems found
- Equipment periodic maintenance and calibration records are complete
- Hazard rectification is closed-loop
- Operators strictly follow operating procedures
- No violations exist
- All safety management requirements are implemented effectively
