Silver Nitrate Used in photographic, mirror, silver, hidden and non-fading ink, dyeing, porcelain, coloring, etching ivory and chemical analysis of important reagents, Silver Nitrate medical for antivirus, astringent, neonatal ophthalmia Prevention and veterinary treatment for wound and local inflammation.
Animal test can lead to hemolytic anemia and pulmonary edema, repeated small doses of silver injection, can cause anemia, myeloproliferation, tissue and organogenesis, especially the glomerular basement membrane silver calm, can lead to thickening of the basement membrane.
Short-term excess of the skin and mucous membranes have a stimulating effect and corrosive effect on the respiratory tract damage caused by bronchitis, respiratory submucosal silver calm, silver calm first appeared in the conjunctiva, after taking silver nitrate digestive tract mucous membrane is corrosive.

And organic matter coexistence with the case of light black, Silver Nitrate if hydrogen sulfide, with or without light are black. Can be decomposed by heating and silver.
Skin: Wear protective clothing to avoid skin contact.
Eyes: with chemical safety goggles.
Inhalation: Must be equipped with respirator to prevent excessive intake of silver nitrate dust or its mixture.
After taking the silver nitrate, can quickly inhalation of concentrated salt water, and 2% sodium chloride injection slowly gastric lavage, so that the formation of silver chloride precipitation, and to other symptomatic treatment. Skin and eye mucosal silver calm, can be used sodium thiosulfate and potassium ferricyanide mixture, local intradermal or subconjunctival injection, have a certain effect.
In order to prevent the decomposition of silver nitrate, Silver Nitrate can be stored in brown bottles or dark containers, in the low temperature, ventilation, far organic matter and easy to oxidize the material at the preservation.
Occurrence of leakage, should wear protective masks and gloves. Rinse with water and dilute the effluent into the wastewater system.
