As an accredited Coal Gas factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Coal Gas is supplied in high-pressure steel cylinders, each containing 50 liters, clearly labeled with hazard symbols and usage instructions. |
| Shipping | **Shipping Description for Coal Gas:** Coal gas is transported as a compressed or liquefied gas in high-pressure cylinders or tankers. It is classified as a flammable gas (UN 1012). Containers must be clearly labeled and handled according to international regulations. Proper ventilation, leak detection, and grounding are essential during shipping. |
| Storage | Coal gas is typically stored in large, airtight gas holders or gasometers, which safely contain the gas under low pressure. These storage vessels are made of steel and are designed to prevent leaks and minimize risks of explosion. Proper ventilation, regular inspections, and strict safety protocols are essential to manage the flammability and toxicity of coal gas during storage. |
