  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Above 77°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 77°C use a closed system and ventilation.  Use water spray, powder, foam, carbon dioxide.   

 AVOID ALL CONTACT! PREVENT GENERATION OF MISTS! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Burning sensation. Cough. Sore throat. Headache. Shortness of breath. Drowsiness. Nausea.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation. Sore throat. Nausea. Vomiting. Drowsiness.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH PUNGENT ODOUR. TECHNICAL-GRADE PRODUCT: AMBER-TO-DARK BROWN LIQUID. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on heating above the boiling point. This produces toxic and corrosive fumes including hydrogen bromide and hydrogen chloride. Reacts in the presence of water with aluminium, magnesium, tin and their alloys. Attacks some forms of rubber and coatings. 

Formula: C3H5Br2Cl
Molecular mass: 236.4
Boiling point: 196°C
Melting point: 6°C
Relative density (water = 1): 2.1
Solubility in water, g/l at 20°C: 1.2 (poor)
Vapour pressure, Pa at 20°C: 77
Relative vapour density (air = 1): 8.16
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01
Flash point: 77°C o.c.
Octanol/water partition coefficient as log Pow: 2.96  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system and kidneys. This may result in impaired functions. Exposure could cause lowering of consciousness. 

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

Effects of long-term or repeated exposure
The substance may have effects on the liver, lungs, kidneys and testes. This may result in impaired functions and tissue lesions. May cause heritable genetic damage to human germ cells. This substance is probably carcinogenic to humans. Causes toxicity to human reproduction or development. 


OCCUPATIONAL EXPOSURE LIMITS
MAK: skin absorption (H); carcinogen category: 2.
MAK: germ cell mutagen group: 2 

ENVIRONMENT
The substance is harmful to aquatic organisms. The substance may cause long-term effects in the aquatic environment. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
An added stabilizer or inhibitor can influence the toxicological properties of this substance; consult an expert.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
