Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 5°C (except when it is packed in a pressurized container). The humidity in the warehouse is preferably not more than 85%. The packaging is required to be sealed and not in contact with the air. It should be stored separately from oxidants and alkalis, and should not be mixed. It should not be stored in large quantities or stored for a long time. Use explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to sparks. Storage areas should be equipped with emergency release equipment and suitable containment materials.
