TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 48°C explosive vapour/air mixtures may be formed.  Above 48°C use a closed system, ventilation and explosion-proof electrical equipment.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   STRICT HYGIENE!   
Inhalation   Use ventilation.  Fresh air, rest. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Reacts violently with a mixture of iodine pentafluoride and tetrafluoroethylene. This generates fire and explosion hazard. Reacts with oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: 20 ppm, 110 mg/m³; Peak limitation category: II(2); Pregnancy risk group: C; Sensitization of skin (SH); (DFG 2005). 

Routes of exposure
 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance is irritating to the skin. The substance is mildly irritating to the eyes. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. See Notes.
