safety information

msds information

sodium fluoride usage and synthesis

chemical properties	white crystalline
general description	sodium fluoride is a colorless crystalline solid or white powder, or the solid dissolved in a liquid. sodium fluoride is soluble in water. sodium fluoride is noncombustible. sodium fluoride is corrosive to aluminum. sodium fluoride is used as an insecticide. sodium fluoride is also used to fluorinate water supplies, as a wood preservative, in cleaning compounds, manufacture of glass, and for many other uses.
air & water reactions	sodium fluoride is soluble in water.
reactivity profile	sodium fluoride reacts with acids to form corrosive and toxic, hf [handling chemicals safely 1980 p. 842].
health hazard	ingestion may cause vomiting, abdominal pain, diarrhea, convulsions, collapse, thirst, disturbed color vision, acute toxic nephritis.
fire hazard	non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). contact with metals may evolve flammable hydrogen gas. containers may explode when heated.
