Q: The emergency measures?
Skin contact: Take off contaminated clothing immediately, rinse with plenty of running water for at least 15 minutes, seek medical attention.
Eye contact: Immediately lift the eyelids, rinse thoroughly with plenty of running water or saline for at least 15 minutes, seek medical attention.
Inhalation: Quickly leave the scene to a place with fresh air, keep the respiratory tract unobstructed, and give oxygen if breathing is difficult. If breathing has stopped, give artificial respiration immediately and seek medical attention.
Ingestion: Rinse mouth with water, drink milk or egg white, seek medical attention.
Q: Fire-fighting measures?
Hazardous characteristics: Toxic sulfide fumes will be produced when decomposed by high heat.
Hazardous combustion products: carbon monoxide, carbon dioxide, sulfides.
Fire extinguishing method: firefighters must wear gas masks, and put out the fire in the upwind direction outside the safe distance. Extinguishing agent: mist water, foam, dry powder, carbon dioxide, sand.
Q: Spill emergency treatment?
Emergency treatment: Isolate the leaked contaminated area and restrict access. Cut off the fire source. It is recommended that emergency personnel wear dust masks and protective suits. Collect it with a clean shovel in a dry, clean container with a cover, and transfer it to a safe place. It can also be washed with a large amount of water, and the washed water is diluted and put into the waste water system. If a large amount of leakage occurs, collect and recycle or transport to a waste disposal site for disposal.
