    Packing & Storage
    Packing Hydrogen Selenide [Anhydrous], 99.99%, 50g—supplied in a sealed, corrosion-resistant steel cylinder with safety valve and clear hazard labeling.
    Shipping **Hydrogen Selenide [Anhydrous]** is shipped as a compressed, toxic, and flammable gas in high-pressure cylinders. Containers must be clearly labeled, tightly sealed, and transported upright. Emergency response and leak detection provisions are required, in compliance with relevant regulations (e.g., DOT, IATA, IMDG) due to its acute toxicity and environmental hazards.
    Storage Hydrogen Selenide [Anhydrous] should be stored in tightly sealed, corrosion-resistant cylinders under an inert atmosphere, in a cool, dry, and well-ventilated area away from heat, sparks, or open flames. Storage areas must be equipped with gas detection and emergency ventilation. It must be isolated from oxidizers, strong acids, and incompatible materials. Proper hazard labeling and secure containment are essential.
