Prevent steam from leaking into the air in the workplace. Avoid contact with oxidants and acids. Filling should control the flow rate and prevent static electricity from accumulating. When handling, it should be lightly loaded and unloaded to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Empty containers may remain harmful substances.
2. ** Storage precautions **: Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30 ° C. Keep the container sealed. It should be stored separately from oxidants and acids, and do not mix storage. Use explosion-proof lighting and ventilation facilities. The use of mechanical equipment and tools that are prone to generating sparks is prohibited. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
