Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The temperature should not exceed 30°C. Keep the container sealed. Should be stored separately from oxidants, acids, etc. Avoid mixing. Not suitable for large-scale storage or long-term storage. Use explosion-proof lighting and ventilation facilities. Do not use mechanical equipment and tools that are prone to sparks. Storage areas should be equipped with spill emergency treatment equipment and suitable containment materials.
