| Capacity and Fill Level | Select a drum that leaves adequate headspace for thermal expansion. Do not fill beyond the container’s marked or approved limit. | At every filling operation | The container is not overfilled, swollen, distorted, or exposed to excessive heat. |
| Identification | Mark the contents, grade, hazard information, fill date, and responsible department. Keep labels readable and firmly attached. | At filling and during routine inspections | Contents can be identified without opening the drum, and incompatible materials are clearly segregated. |
| Leak and Corrosion Inspection | Check the shell, seams, bung, gasket, valve, base, and contact points for leaks, rust, dents, abrasion, or chemical attack. | Before use and at least monthly while in storage | No active leakage, severe corrosion, structural damage, or defective closure components. |
| Storage Location | Store in a cool, dry, well-ventilated area away from ignition sources, direct sunlight, drains, incompatible chemicals, and vehicle impact. | Continuous control; verify during inspections | The area is clean, access-controlled, protected from impact, and compliant with applicable fire and environmental requirements. |
| Secondary Containment | Place drums on a spill pallet, bund, or other suitable containment system sized for the stored volume and local requirements. | Check weekly and after any spill or heavy rain | Containment is intact, unobstructed, free of accumulated liquid, and large enough for the storage arrangement. |
| Closure Maintenance | Keep bungs and caps tight, replace damaged gaskets, clean threads, and use only fittings rated for the stored liquid. | After each transfer and during monthly inspection | Closures are secure, seals are pliable and undamaged, and no residue indicates seepage. |
| Handling and Movement | Use suitable drum-handling equipment. Do not drag, roll uncontrolled, drop, or lift a drum by its bung or valve. | Every movement | The drum remains upright and stable, with no impact damage or displaced closure. |
| Stock Rotation | Use a first-in, first-out system where practical. Record receipt dates and inspect fuel for water, sediment, or degradation before use. | Review monthly or according to the fuel supplier’s storage guidance | Older stock is used first and questionable fuel is quarantined for evaluation. |
| Emergency Readiness | Maintain suitable spill-control materials, fire protection, warning signs, emergency contacts, and trained personnel. | Inspect monthly and after every use | Equipment is accessible, serviceable, correctly rated, and included in the site emergency plan. |
| Retirement or Disposal | Remove drums from service when they leak, are severely corroded, structurally damaged, contaminated, or no longer meet applicable requirements. | Immediately when a defect is found | The container is isolated, labeled, and handled through an authorized waste or recycling process. |
