It is recommended that operators wear self-priming filter gas mask (half-mask), chemical safety protective glasses, gas permeable work clothes, and rubber oil-resistant gloves. Keep away from fires and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor from leaking into workplace air. Avoid contact with oxidants and acids. Operate the disposal in nitrogen. Handle with care to prevent damage to packing and container. Equipped with the appropriate variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Empty containers may retain harmful substances.

Storage Precautions 

Store in a cool, ventilated warehouse. Keep away from fire and heat. Packing must be sealed and not in contact with air. Should be stored separately with oxidants, acids, food chemicals, do not mix storage. Explosion-proof lighting and ventilation facilities are adopted. The use of spark-prone mechanical equipment and tools is prohibited. The storage area shall be equipped with leakage emergency treatment equipment and appropriate containment materials.
