0399 n-BUTYL ACETATE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. The substance can be absorbed into the body by inhalation of
its vapour.
Physical dangers
Inhalation risk
The vapour is heavier than air and may travel along the ground;
distant ignition possible. A harmful contamination of the air will be reached rather slowly
on evaporation of this substance at 20掳C.
Chemical dangers
Effects of short-term exposure
Reacts with strong oxidants, strong acids, strong bases causing
fire and explosion hazard. Attacks many plastics and rubber. The substance is irritating to the eyes and the respiratory tract.
The substance may cause effects on the central nervous
system. Exposure far above the OEL could cause lowering of
Occupational exposure limits
consciousness.
TLV: 150 ppm as TWA; 200 ppm as STEL; (ACGIH 2003).
MAK: 100 ppm, 480 mg/m3; Peak limitation category: I(2);
Effects of long-term or repeated exposure
Pregnancy risk group: C; (DFG 2003).
The liquid defats the skin.
