Storage method
Storage Precautions[14] Store in a cool, dry and well-ventilated warehouse. keep awayFire, heat source. The storage temperature does not exceed 32°C and the relative humidity does not exceed 80%. Keep container tightly sealed. They should be stored separately from oxidants, acids, alkalis, amines, etc., and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.
