Chemical Safety
0506 2-METHYL-1-BUTANOL
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
and by ingestion.
Occupational exposure limits
TLV not established. Inhalation risk
A harmful contamination of the air will be reached rather slowly on
evaporation of this substance at 20/C.
Effects of short-term exposure
The substance irritates the eyes, the skin and the respiratory tract.
Swallowing the liquid may cause aspiration into the lungs with the risk of
chemical pneumonitis. The substance may cause effects on the central
nervous system.
Effects of long-term or repeated exposure
The liquid defats the skin.
