Conditions of storage

Storage Precautions Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the warehouse should not exceed 37℃. The package should be sealed and not in contact with air. It should be stored separately from oxidizers and acids, and should not be mixed. Do not store in large quantities or for a long time. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that can easily generate sparks. The storage area should be equipped with leak emergency treatment equipment and suitable holding materials.
