Additional information
Justification for classification or non-classification
Classification according to GHS:
No LD50or LC50values for acute toxicity are available. Fluorosulphuric acid is harmonised classified as Acute Tox. 4 (H332: Harmful if inhaled) according to GHS (016-018-00-7). Based on the available toxicological data of HF, the fluorosulphuric acid is expected to be toxic by inhalation. Therefore the classification of fluorosulphuric acid as Acute Tox. 3 (H331 Toxic if inhaled) is recommended. Since fluorosulphuric acid is corrosive the additional labelling EUH071 (Corrosive to the respiratory tract) is recommended. Fluorosulphuric acid rapidly hydrolyses in water to its hydrolysis products H2SO4and HF. For fluorosulphuric acid therefore the additional labelling EUH029 (Contact with water liberates toxic gas) is recommended.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
