Leakage emergency treatment
Isolate the leakage contaminated area and restrict access.It is recommended that emergency treatment personnel wear self-priming filter type dust masks and gas suits.Do not touch the leakage directly.Small amount of leakage: avoid raising dust and collect it in a dry, clean and covered container with a clean shovel.Large amount of leakage: cover with plastic cloth and canvas to reduce flying, and then collect and recycle or transport to waste disposal site for disposal.
Protective measures
Respiratory system protection: wear a self-priming filter type dust mask when it may be exposed to dust.
Eye protection: wear chemical safety goggles.
Body protection: wear adhesive tape anti-virus clothing.
Hand protection: wear rubber gloves.
Others: Smoking, eating and drinking are prohibited at the work site.After work, take a shower and change clothes.Store the clothes contaminated by poisons separately and use them after washing.Keep good hygiene habits.
First aid measures
Skin contact: Take off the contaminated clothes and wash the skin thoroughly with soapy water and clean water.Get medical attention.
Eye contact: Lift the eyelid and flush with flowing water or physiological saline.Get medical attention.
Inhalation: quickly leave the site to a place with fresh air.Keep the respiratory tract unobstructed.If breathing is difficult, give oxygen.If breathing stops, perform artificial respiration immediately.Get medical attention.
Ingestion: drink enough warm water to induce vomiting.Get medical attention.
Fire extinguishing method: spray water to cool the container, and move the container from the fire site to an open place if possible.Extinguishing agent: fog water, sand.It will explode when mixed with combustibles in the fire site.Firefighters must operate in an explosion-proof shelter.Do not spray water directly onto molten materials to avoid serious flowing fire or severe boiling splash.
