| Field | Value |
|---|---|
| GHS Signal Word | DANGER |
| GHS Hazard Statements | Highly flammable liquid and vapour Toxic in contact with skin Harmful if swallowed or if inhaled Causes severe skin burns and eye damage May cause respiratory irritation Harmful to aquatic life |
| Short-term Effects | The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. Inhalation may cause pneumonitis. Exposure at high levels could cause severe swelling of the throat. Medical observation is indicated. |
| Long-term Effects | Lungs may be affected by repeated or prolongated exposure to the vapour. The substance may have effects on the teeth. This may result in erosion. |
| Routes of Exposure | The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. |
