TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion See Effects of long-term or repeated exposure.  Do not eat, drink, or smoke during work.  Rinse mouth.

excl mark;warncancer;health haz

EMERGENCY RESPONSE SAFE STORAGE
  Separated from strong oxidants, strong bases and magnesium. Ventilation along the floor. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive gases including hydrogen bromide and hydrogen chloride. Reacts with strong bases, strong oxidants and magnesium. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 2; Germ cell mutagen group: 3B; Skin absorption (H); (DFG 2007). 

Routes of exposure
The substance can be absorbed into the body by ingestion. 

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
Ingestion may cause effects on the kidneys and liver. This may result in impaired functions. This substance is possibly carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
