| Packing | Alum is packaged in a sealed, moisture-proof 1 kg plastic pouch, labeled with chemical name, safety precautions, and handling instructions. |
| Storage | Alum should be stored in a cool, dry, and well-ventilated area, away from moisture and incompatible substances such as strong acids and bases. It should be kept in tightly sealed containers, preferably glass or plastic, to prevent clumping and contamination. Storage areas must be clearly labeled, and access should be limited to trained personnel to ensure safety and chemical integrity. |
| Shipping | Alum is shipped in tightly sealed bags, drums, or containers made from materials resistant to its mildly corrosive nature, such as polyethylene or polypropylene. Packages are clearly labeled with appropriate hazard warnings. Shipments should be kept dry and stored in a cool, ventilated area to prevent moisture absorption and clumping. |
