5. Production and preparation method: crystal separation, please refer to the relevant data for details

6. Dangerous category: category 3.3 inflammable

7. Fire control measures: cut off the fire source. It is suggested that emergency personnel wear self-contained positive pressure breathing apparatus and fire protective clothing. Cut off the source of leakage as much as possible. Prevent access to sewer, drainage ditch and other restrictive space. Small leakage: absorption with activated carbon or other inert materials. Large leakage: build a dike or dig a pit. Cover with foam to inhibit evaporation. Transfer to tanker or special collector with explosion-proof pump, recycle or transport to waste disposal site for disposal.

How to extinguish the fire: spray cooling containers, and if possible move the containers from the fire site to an open area. Extinguishing agent: foam, carbon dioxide, dry powder, sand.

8. First aid treatment: skin contact: remove contaminated clothing and rinse skin thoroughly with soap and water. Eye contact: lift eyelid and rinse with flowing water or normal saline. Go to a doctor. Inhalation: leave the site quickly to the fresh air, keep the airway open. If breathing stops, give artificial respiration immediately. Go to a doctor. Ingestion: drink adequate amount of warm water, induce vomiting, seek medical advice.

9. Packaging, storage and transportation: the paint bucket or galvanized bucket is packed with 160-170kg/ drum and stored in a cool and ventilated warehouse. Stay away from fire and heat. The temperature inside the warehouse should not exceed 30℃. Prevent direct sunlight. It should be stored separately from oxidant. Outside. Equipped with the corresponding variety and quantity of fire equipment. Mechanical equipment and tools that produce sparks are prohibited. When filling, pay attention to the flow rate (not more than 3m/s), and there is an grounding device to prevent the accumulation of static electricity. Transport with professional dangerous goods vehicles.
