Hazard Statements
Highly flammable liquid and vapour Harmful if swallowed Causes serious eye irritation May cause damage to organs through prolonged or repeated exposure
Short-term Exposure Effects
The substance is severely irritating to the eyes. The vapour at high levels is irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system.
Long-term Exposure Effects
The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the upper respiratory tract and central nervous system. This may result in irritation, headache, fatigue and lack of concentration. See Notes.
Routes of Exposure
The substance can be absorbed into the body by inhalation of its vapour and by ingestion.
