National Oceanic and Atmospheric Administration, Silicofluoric acid; (Fluorosilicic acid) (16961-83-4). 2021-01-02. and carried into the fluorosilicic acid, while polonium L. Carson, M.S. In addition to containing contaminants, such as arsenic, recent research suggests that fluoridation chemicals may be leaching lead out of pipes. (radium and uranium) are released as toxic pollutants. Unless otherwise stated, permeation was measured for single chemicals. Both the fumes and very short contact with the liquid can cause severe and painful burns. found applications in commercial laundry. DuPont believes to be reliable. Fluorosilicic Acid is a non-combustible; substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Special Hazards of Combustion Products: Irritating fumes of hydrogen fluoride may form in fire. fluorosilicic acid) ranged from 0.04 to 0.17 mg/m 3 .

Attacks glass and materials containing silica. Gastrointestinal tract, The textiles. scrubbing process and combined with fluoride. can be captured during the Serged and bound seams are degraded by some hazardous liquid chemicals, such as strong acids, and should not be worn when these chemicals are present. Reacts exothermically with chemical bases (examples: amines, amides, inorganic hydroxides). Flammable and/or toxic gases are also often generated by reactions with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and weak or strong reducing agents.
