4.Operational disposal and storage
Operation precautions: closed operation, local exhaust air. Operators must be specially trained and strictly follow the operating procedures. It is recommended that operators wear self-priming filter dust mask, chemical safety protective glasses, rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Keep away from fire and heat. No smoking in the workplace. Use explosion-proof ventilation systems and equipment. Avoid dust. Avoid contact with oxidants, reducing agents and acids. Handling should be light, to prevent damage to the packaging and containers. Equipped with corresponding varieties and quantities of fire equipment and leakage emergency treatment equipment. Empty containers may retain harmful substances.
Storage precautions: Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat source. Keep the container airtight. It should be stored separately from oxidants, reducing agents, acids and edible chemicals, and should not be mixed. Equip the appropriate type and quantity of fire fighting equipment. The storage area shall be equipped with suitable materials to hold the leakage. Warranty period: 3 months from the date of manufacture.
