Nickel cyanide is an inorganic compound with the chemical formula of Ni (CN)twoIt is a green crystalline powder, soluble in potassium cyanide, ammonium hydroxide and alkali, slightly soluble in dilute acid and insoluble in water. It is mainly used as a component of electroplating bath and metallurgy, as well as for refining and quantitative analysis of benzene and as an anti-corrosion agent for metals.
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 nickel compounds were included in the list of Class 1 carcinogens.[2]
Solubility: soluble in potassium cyanide, ammonium hydroxide, alkali, slightly soluble in dilute acid, insoluble in water

First aid measures
Announce
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.Use 1:5000 potassium permanganate or 5% sodium thiosulfate solution for gastric lavage.Get medical attention.
Fire fighting measures

edit
Hazard characteristics: violent reaction with magnesium.It can form explosive mixture with chlorate or sodium nitrite.When exposed to acid or air, it can absorb water and carbon dioxide and decompose into highly toxic hydrogen cyanide gas.High toxic smoke will be released in case of high thermal decomposition.
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.Then select appropriate extinguishing agent to extinguish the fire according to the cause of fire.
Leakage emergency treatment
Announce
edit
Isolate the leakage contaminated area and restrict access.It is recommended that emergency personnel wear dust masks and gas suits.Do not touch the leakage directly.
Small amount of leakage: avoid raising dust, carefully sweep and transfer to a safe place.
Large amount of leakage: collect and recycle or transport to waste disposal site for disposal.
Protective measures
Announce
edit
Respiratory system protection: wear a filtered gas mask (half mask) when the concentration in the air exceeds the standard.When rescuing or evacuating in an emergency, a portable respirator should be worn.
Hand protection: wear rubber oil resistant gloves.
Eye protection: wear chemical safety protection eyes.
Skin and body protection: wear work clothes to prevent poison penetration.
Handling and storage
Announce
edit
Precautions for operation: closed operation, providing sufficient local ventilation.Prevent dust from releasing into the workshop air.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.Avoid dust generation.Avoid contact with acids, magnesium chloroformate, sodium nitrite and potassium nitrite.Provide leakage emergency treatment equipment.Empty containers may leave harmful substances.
Precautions for storage: store in a cool, dry and well ventilated warehouse.Keep away from kindling and heat sources.Protect from direct sunlight.Packing and sealing.It shall be stored separately from acids, magnesium chloroformate, sodium nitrite, potassium nitrite, food chemicals, etc., and mixed storage is strictly prohibited.The storage area shall be equipped with appropriate materials to contain leakage.
