Precautions for operation: Closed operation, pay attention to ventilation. The operation is as mechanized and automated as possible. Operators must undergo special training and strictly abide by operating procedures. It is recommended that operators wear a hood-type electric air-supplied filtering dust respirator, acid-base-proof plastic work clothes, and rubber acid-base-proof gloves. Avoid generating dust. Avoid contact with alkalis. When handling, it should be lightly loaded and unloaded to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues

Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The packaging is required to be sealed and not in contact with the air. It should be stored separately from alkalis, and should not be mixed. Storage areas should be provided with suitable materials to contain spills.
