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

CHEMICAL DANGERS:
Reacts violently with a mixture of iodine pentafluoride and tetrafluoroethylene, causing fire and explosion hazard. Reacts with oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 20 ppm, 110 mg/m; sensitization of skin (Sh); Peak limitation category: II(2); Pregnancy risk group: C; (DFG 2005).
INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the skin and is mildly irritating to the eyes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization (see Notes).
