OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 ppm (as TWA); Skin; (ACGIH 2005).
MAK not established. (DFG 2007).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by ingestion.

INHALATION RISK:
A harmful contamination of the air will be reached quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin, and the respiratory tract. Corrosive on ingestion.
