Endpoint summary
Administrative data
Description of key information
Because the substance H2ZrF6 is a highly corrosive liquid (Skin Corr. 1A, H314: Causes severe skin burns and eye damage), no experimental studies investigating acute oral, dermal or inhalation toxicity are available. By way of expert judgement, taking into consideration the corrosivity and the degree of acute toxicity of other inorganic fluorides, specifically of hydrofluoric acid, which is an impurity in H2ZrF6, H2ZrF6 is classified as follows: Acute Tox 3, with the hazard statements H301: Toxic of swallowed, H311 Toxic in contact with skin, and H331 Toxic if inhaled. This classification is equivalent to the classification of a 1-7% solution of hydrofluorid acid.
