The operation, storage, and transportation of lanthanum oxide
Lanthanum oxide is slightly soluble in water and easily soluble in acid to generate corresponding salts. It is easy to absorb carbon dioxide and water when exposed to the air and gradually becomes lanthanum carbonate. The burning lanthanum oxide combines with hydration to give off a lot of heat. Due to the above physical and chemical characteristics, the operation, storage, and transportation of lanthanum oxide have special requirements.
Pay attention to the operation of lanthanum oxide: airtight operation and full ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear filter-type gas masks (half masks), safety glasses, anti-static overalls, and rubber oil-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent the vapor from leaking into the air in the workplace. Avoid contact with oxidants, acids, alkalis. When filling, the flow rate should be controlled, and there should be a grounding device to prevent the accumulation of static electricity. When handling, please load and unload with care to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
Attention should be paid when lanthanum oxide is stored: usually, commercial products have polymerization inhibitors. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C. The packaging is required to be sealed and not in contact with air. It should be stored separately from oxidants, acids, alkalis, etc., and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials.
When lanthanum oxide is transported, it should be noted that the transport vehicle should be equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. It is best to transport sooner or later in summer. The tank (tank) truck used during transportation should have a grounding chain, and a hole partition can be set in the tank to reduce vibration and static electricity. Mixed shipment and transportation with oxidants, acids, alkalis, edible chemicals, etc. are strictly prohibited. Avoid exposure to the sun, rain, and high temperature during transportation. Stay away from fire, heat sources, and high-temperature areas during stopovers. The exhaust pipe of the vehicle carrying the item must be equipped with a fire arrester, and it is forbidden to use mechanical equipment and tools that are prone to sparks for loading and unloading. When transporting by road, follow the prescribed route and do not stop in residential areas and densely populated areas. It is forbidden to drop off during railway transportation. It is strictly forbidden to transport in bulk by wooden ships or cement ships.
