Indeed, undetected or untreated spill and leaks can cause deterioration of containers by corrosion effect of metal drums or dirt of bags. It may cause contamination of warehouse staff and emission of toxic fumes or flammable vapors. Similarly, the deterioration of packaging of powder pesticide formulations can lead to their dissemination by the wind or the aeration system/ventilation and cause powdery deposits around the storage site if they are not stabilized first.
