IMPORTANT DATA
Physical State; Appearance Routes of exposure
YELLOW - BROWNISH VISCOUS LIQUID. The substance can be absorbed into the body by inhalation of its
vapour, through the skin and by ingestion.
Chemical dangers
Inhalation risk
On combustion, forms toxic and corrosive gases (nitrogen
oxides). Reacts violently with strong oxidants. Attacks many No indication can be given about the rate in which a harmful
plastics. concentration in the air is reached on evaporation of this
substance at 20/C.
Occupational exposure limits
Effects of short-term exposure
TLV not established.
The substance may cause effects on the red blood cells, resulting
in formation of methaemoglobin. The effects may be delayed.

ENVIRONMENTAL DATA
NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
