As an accredited Helium [Compressed Or Liquefied] factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | A high-pressure steel cylinder containing 50 liters of Helium [Compressed Or Liquefied], labeled with hazard warnings and secure valve cap. |
| Shipping | Helium, shipped as either compressed gas or refrigerated liquid, must be transported in DOT-approved cylinders or dewars, clearly labeled with hazard class 2.2 (non-flammable gas). Secure containers upright to prevent damage. Avoid heat, ignition sources, and rough handling. Follow all relevant regulatory guidelines for safe shipping and storage. |
| Storage | Helium [Compressed or Liquefied] should be stored in well-ventilated, dry, and cool areas away from combustible materials and direct sunlight. Cylinders must be secured upright to prevent tipping and protected from physical damage and heat sources. Storage should comply with local regulations, with proper labeling and access limited to authorized personnel, ensuring emergency equipment is available nearby. |
