Precautions for operation: Closed operation, comprehensive ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear filtered gas masks (half masks), anti-static work clothes, and rubber oil resistant gloves. Keep away from sparks and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor leakage into the air of the workplace. Avoid contact with oxidants. When filling, the flow rate should be controlled and there should be a grounding device to prevent the accumulation of static electricity. 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. The temperature of the warehouse should not exceed 30 ℃. Keep the container sealed. It should be stored separately from oxidants and should not be mixed for storage. Using explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency response equipment for leaks and suitable storage materials.
