IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
VISCOUS COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: IIb (not established but data is available) (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is slightly irritating to the eyes and the skin. Exposure at high levels of the vapour may result in irritation of the eyes and upper respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis.
