Physical dangers
 

Chemical dangers
Reacts with acids, bases, alcohols and amines. Decomposes on burning. This produces irritating fumes. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour and by ingestion. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes. Ingestion could cause effects on the central nervous system. This may result in respiratory failure. Exposure could cause lowering of consciousness. 

Effects of long-term or repeated exposure
