GHS Hazard Classification

Reported hazard statements	H301, H311, H331, H314 (11.1%), H318 (32.3%), H330 (11.1%), H341 (11.1%), H361 (11.1%)

Documented Uses

• Used in silver soldering fluxes, glass etching, water fluoridation, and as a preservative and insecticide; [HSDB]
• Soldering [Category: Heat or Machine]
• Glass Manufacturing [Category: Industry]
• Since 1991, fluoridated salt has been on sale in household-size packages in Germany. Potassium or sodium fluoride is added to iodized salt until the fluoride concentration reaches 250 mg/kg.
• Salt fluoridation is recognised world-wide as a proven and viable alternative means of consumer choice-related, community-based fluoridation where water fluoridation is either technically or politically impossible. ...Most salt consumed is contained within cooked food products, rather than sprinkled over prepared food at the table.../Fluoride salts/
• ... Used in preparing silver soldering fluxes. ... In organic synthesis as a catalyst for various reactions or to introduce fluorine into organic molecules. ... In France, potassium fluoride may be added to table salt to increase resistance to dental caries.
