Chemical Safety
0211 ADIPONITRILE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
ODOURLESS OILY COLOURLESS LIQUID. The substance can be absorbed into the body by inhalation and
through the skin and by ingestion.
Chemical dangers
Inhalation risk
The substance decomposes on heating or on burning producing
highly toxic hydrogen cyanide (see ICSC 0492). Reacts violently A harmful contamination of the air will not or will only very slowly
with strong oxidants. be reached on evaporation of this substance at 20/C.
Occupational exposure limits Effects of short-term exposure
TLV: 2 ppm as TWA; (skin); (ACGIH 2004). The substance irritates the eyes and the skin. Exposure could
cause convulsions. Exposure may result in unconsciousness.
Exposure may result in death. Medical observation is indicated.
Effects of long-term or repeated exposure
The substance may have effects on the blood and adrenals,
resulting in anaemia and tissue lesions.
