| First Aid | Skin contact: Remove contaminated clothing and rinse skin thoroughly with soapy water and water. EYE CONTACT: Lift eyelids and flush with running water or saline. Seek medical attention. Inhalation: Remove from scene to fresh air. Keep airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention. Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention. | |||||
| storage and transportation conditions | Storage Precautions:Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat source. Packaging must be complete and sealed to prevent moisture absorption. Store separately from oxidizers and avoid mixing. The storage area should be equipped with suitable materials to shelter the leakage. Transportation precautions: Railway transportation should be strictly in accordance with the Ministry of Railways “Rules for the Transportation of Dangerous Goods” in the dangerous goods assembly table for assembly. Packing should be complete and loading should be stable. During transportation, we should make sure that the containers do not leak, collapse, fall or get damaged. It is strictly prohibited to mix and transport with strong oxidizing agents and edible chemicals. Transportation vehicles should be equipped with leakage emergency treatment equipment. During transportation, it should be protected from exposure to sunlight, rain and high temperature. | |||||
| Spill handling | Isolate the leaking contaminated area and restrict access. It is recommended that emergency personnel wear dust masks (full face masks) and anti-virus clothing. Do not come into direct contact with the spill. Small spills: Collect with a clean shovel in a dry, clean, covered container. Large spills: Collect and recycle or transport to a waste disposal site for disposal. | |||||
