Description
Sodium hydrogen sulfide is a yellow, solid flake with a sulfurous (rotten egg) smell. It is used in water treatment, the pulp and paper industry, and in leather processing as a tanning agent or hair remover (from hides). Sodium hydrogen sulfide may be used in the making of colors and dyes. It can also be used in the manufacture of other chemicals, metals or in ore processing (mining) and in waste water, soil and process sludge treatment.

Health Information :
Contact – Skin exposures can cause symptoms ranging from severe skin irritation or itching to redness and swelling. Eye exposure to sodium hydrogen sulfide may result in redness, tearing or severe eye irritation and damage.
Inhalation – The inhalation of sodium hydrogen sulfide dusts can cause nose and throat irritation or coughing. Repeated or prolonged exposures may cause sore throat or nosebleeds. Inhalation may also cause severe respiratory reactions and aggravate asthma or other breathing diseases.
Ingestion – The ingestion of sodium hydrogen sulfide may cause severe irritation or burns of the mouth and throat, nausea, vomiting and diarrhea. There is danger of perforating (puncturing) the esophagus or stomach. Other Effects – The International Agency for Research on Cancer (IARC) has not classified sodium hydrogen sulfide as a carcinogen (cancer causing).
