Vanadium pentoxide is a metal oxide with chemical formula VtwoOfiveIt is widely used in metallurgy, chemical industry and other industries, mainly for smelting ferrovanadium.
On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization (WHO) was preliminarily sorted out for reference, and vanadium pentoxide was included in the list of Category 2B carcinogens.[2]
It is widely used in metallurgy, chemical industry and other industries, mainly for smelting ferrovanadium.
Leakage emergency treatment
Announce
edit
Isolate the leakage contaminated area and restrict access.It is recommended that emergency personnel wear self-contained positive pressure respirators and anti poison clothing.Avoid flying dust, sweep it carefully, put it in a bag and transfer it to a safe place.In case of large leakage, cover it with plastic cloth and canvas.Collect and recycle or transport to waste disposal site for disposal.
First aid measures

edit
Skin contact: Take off contaminated clothes immediately and wash with plenty of flowing 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 fighting measures

edit
Hazard characteristics: non combustible.React violently in contact with chlorine trifluoride and lithium.
Hazardous combustion products: may produce harmful toxic smoke.
Extinguishing method: firefighters must wear full body fire and gas protective clothing and extinguish the fire upwind.When putting out a fire, try to move the container from the fire site to an open place.
Protective measures
Announce
edit
Respiratory system protection: dust mask (full face mask) must be worn when dust may be exposed.In case of emergency rescue or evacuation, air respirator shall be worn.
Eye protection: protection has been made in respiratory system protection.
Body protection: wear adhesive tape anti-virus clothing.
Hand protection: wear rubber gloves.
Other protection: 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.Pre employment and regular physical examination shall be carried out.
Handling and storage
Announce
edit
Operation precautions: closed operation, local exhaust.Operators must be specially trained and strictly abide by the operating procedures.It is recommended that operators wear dust masks (full face masks), rubber cloth gas jackets and rubber gloves.Keep away from flammable and combustible materials.Avoid dust generation.Avoid contact with acids.Load and unload gently during transportation to prevent damage to packaging and containers.Provide leakage emergency treatment equipment.Empty containers may leave harmful substances.
Precautions for storage: store in a cool and ventilated warehouse.Keep away from kindling and heat sources.It shall be stored separately from combustibles, acids and edible chemicals, and mixed storage is strictly prohibited.The storage area shall be equipped with appropriate materials to contain leakage.The "five pairs" management system for extremely toxic substances shall be strictly implemented.
