Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Empty containers may remain harmful substances.

(2) Precautions for storage
Store in a cool and ventilated warehouse. Keep away from fire and heat sources. Keep the container sealed. It should be stored separately from oxidants and alkalis, and mixed storage should not be avoided. Use explosion-proof lighting and ventilation facilities.
