TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Above 77°C explosive vapour/air mixtures may be formed.  Above 77°C use a closed system and ventilation.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   AVOID ALL CONTACT! PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Burning sensation. Cough. Sore throat. Headache. Shortness of breath. Weakness.  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.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

NFPA Code: H2; F1; R1. 
Separated from food and feedstuffs and metals such as aluminium or magnesium. 

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

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
Decomposes on heating above the boiling point. Decomposes on burning. This produces toxic 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. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 2; Germ cell mutagen group: 2; Skin absorption (H); (DFG 2002).
EU OEL ( selected):. 

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

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. This substance is possibly carcinogenic to humans. Causes toxicity to human reproduction or development.
