1. Regularly inspect the iron drum for corrosion, bumps, defects, dents, and leaks. Put defective iron drums in separate secondary packaging drums or leak emergency buckets.
2. Make sure that the iron bucket has its own suitable cover and is sealed tightly.
3. Accurately identify waste oil drums.
4. Make sure that the drum is compatible with the contents. For example, don't put acid in ordinary iron buckets or solvents in plastic buckets.https://www.fhpails.com/
