| GHS Signal Word | DANGER |
| GHS Hazard Statements | Fatal if inhaled Causes severe skin burns and eye damage May cause respiratory irritation May be osive to metals See Notes |
| Short-term Effects | The substance is very corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Exposure could cause asphyxiation due to swelling in the throat. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. Inhalation may cause asthma-like reactions (RADS). Medical observation is indicated. See Notes. |
| Long-term Effects | Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation may cause effects on the lungs. Risk of tooth erosion upon repeated or prolongated exposure to an aerosol of this substance. Mists of this strong inorganic acid are carcinogenic to humans. See Notes. |
| Routes of Exposure | Serious local effects by all routes of exposure. The substance can be absorbed into the body by inhalation of its aerosol. |
