Handling and Storage
Precautions for operation: Closed operation, local ventilation. Prevent dust from being released into the workshop air. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self priming filter type dust masks, chemical safety goggles, work clothes to prevent poison penetration, and rubber gloves. Keep away from sparks and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidants and alkalis. Equip corresponding types and quantities of firefighting equipment and emergency response equipment for leaks. Empty containers may have residual harmful substances.
Storage precautions: Store in a cool and ventilated warehouse. Keep away from sparks and heat sources. Prevent direct sunlight. Packaging sealing. It should be stored separately from oxidants and alkalis, and mixed storage should be avoided. Equip corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with suitable materials to contain leaks
