| Fire-fighting measures | Fire fighting method: spray water to cool the container, and if possible, move the container from the fire scene to an open place. If the container in the fire scene has changed color or produced sound from the safety relief device, it must be evacuated immediately. Extinguishing agent: foam, dry powder, carbon dioxide, sand. Extinguishing with water is ineffective. | ||
| Emergency treatment | Skin contact: Take off contaminated clothing and rinse the skin thoroughly with soap and water. Eye contact: Lift the eyelid, rinse with running water or saline, and seek medical attention. Inhalation: quickly leave the scene to a place with fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately and seek medical attention. Ingestion: Drink enough warm water, induce vomiting, and seek medical attention. | ||
| Packaging, storage, transportation | Packed in paint or galvanized drums of 160-170kg/drum, stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃. Keep the container tightly closed. should be kept away from oxidizer, do not store together. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that easily generate sparks. The barreled stack should not be too large, and the wall distance, top distance, column distance and necessary fire inspection walkways should be reserved. Fire-proof and explosion-proof technical measures must be taken when storing in tanks. It is forbidden to use mechanical equipment and tools that easily generate sparks. Pay attention to the flow rate (not more than 3m/s) when filling, and there is a grounding device. | ||
