Prevent it from flowing into restricted spaces such as sewers and drainage ditches. Small leaks: Adsorb or absorb with sand or other non-combustible materials. It can also be rinsed with a lot of water, diluted with washing water and placed into the wastewater system. Large leaks: Construct embankments or dig pits for containment. Cover with foam to reduce steam disasters. Transfer to a tanker or special collector with an explosion-proof pump, and recycle or transport it to a waste treatment site for disposal.
(7) Operation Disposal and Storage < b ** Operating Precautions **: Closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear filter gas masks (half masks), safety glasses, anti-static overalls, and rubber oil-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam leakage into the air of the workplace. Avoid contact with oxidants, reducing agents, and alkalis. When filling, the flow rate should be controlled, and there should be a grounding device to prevent static electricity accumulation. When handling, it should be handled lightly to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment. Harmful substances may remain in the emptied container.
2. ** Storage Precautions **: Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 29 ° C. Keep the container sealed. It should be stored separately from oxidizing agents, reducing agents and alkalis, and should not be mixed. Use 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 leakage emergency treatment equipment and suitable containment materials.

Prevent flowing into restricted spaces such as sewers and flood drains. Small leaks: Absorb with sand, vermiculite or other inert materials. It can also be scrubbed with an emulsion made of non-flammable dispersant, diluted and placed into the wastewater system. Large leaks: build a dike or dig a pit for containment. Transfer to a tanker or a special collector with a pump, recycle or transport to a waste treatment site for disposal.
(VII) Operation Disposal and Storage
