As an accredited Sulfur Dioxide factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Sulfur Dioxide is supplied in a high-pressure steel cylinder, with a 50 kg net weight, clearly labeled with hazard warnings and handling instructions. |
| Shipping | Sulfur dioxide is shipped as a liquefied, compressed gas in high-pressure steel cylinders or tank cars. It is classified as a toxic and corrosive substance. Shipments must comply with hazardous materials regulations, ensuring proper labeling, ventilation, and emergency procedures to prevent leaks or exposure during transport. Suitable protective equipment is mandatory. |
| Storage | Sulfur dioxide should be stored in tightly sealed, corrosion-resistant containers, such as steel cylinders or tanks, in a cool, dry, and well-ventilated area away from sources of heat, ignition, and incompatible materials like water and oxidizers. Storage areas should be equipped with gas detection and emergency ventilation systems. Proper labeling and segregation from food or combustibles are essential for safety. |
