first-aid

Skin contact: Remove contaminated clothing and rinse thoroughly with soap and water. Eye contact: Immediately lift eyelids and rinse with plenty of running water or saline. Inhalation: Remove quickly from the scene to fresh air. Give oxygen when breathing is difficult. Once breathing stops, begin CPR immediately. Seek medical attention.

Leakage disposal

Evacuate the personnel in the contaminated area to a safe area, prohibit unrelated personnel from entering the contaminated area and cut off the fire source. It is recommended that emergency personnel wear self-contained breathing apparatus and wear general fire protective clothing. Stop leaks while ensuring safety. It is mixed with sand or other non-combustible adsorbent and then collected and transported to a waste disposal site for disposal. If there is a large amount of leakage, use the dike to be contained, and then collect, transfer, recycle or waste after disposal.

Storage and transportation considerations

1 Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. Prevent sun exposure. Keep the container sealed. It should be stored separately from oxidants and acids. Can not be mixed and mixed. Lightly load and unload during handling to prevent damage to packaging and containers. Pay attention to personal protection for dispensing and handling operations. 2 Transportation precautions: Before the transmission, check whether the packaging container is complete and sealed. During transportation, ensure that the container does not leak, collapse, fall or damage. It is strictly forbidden to mix with acids, oxidants, foods and food additives. Transportation is carried out according to the prescribed route.
