Physical dangers
 

Chemical dangers
Reacts with strong oxidants. The substance can form explosive peroxides on exposure to air. 

Occupational exposure limits
TLV: 1 ppm as TWA; 2 ppm as STEL; (ACGIH 2014).
MAK: 1 ppm, 7.1 mg/m³; Peak limitation category: I(1); Pregnancy risk group: C; (DFG 2013). 

Routes of exposure
 

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is mildly irritating to the eyes, skin and upper respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis.
