| Packing | A 2.5-liter brown glass bottle, tightly sealed, features hazard labels and bold “Fuming Sulfuric Acid” text, emphasizing corrosive content. |
| Storage | Fuming sulfuric acid should be stored in tightly sealed, corrosion-resistant containers made of glass or PTFE, in a cool, dry, and well-ventilated area away from direct sunlight and incompatible substances such as organic materials and water. Storage areas must have appropriate acid-resistant flooring and be equipped with spill containment and emergency washing facilities. Access should be limited to trained personnel only. |
| Shipping | Fuming sulfuric acid must be shipped in tightly sealed, corrosion-resistant containers clearly labeled with hazard information. Transport is subject to strict regulations due to its highly corrosive and reactive nature. It should be kept upright, away from incompatible materials, and handled by trained personnel using appropriate protective equipment. |
