TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	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.	Powder, water spray, foam, carbon dioxide.
EXPLOSION	Above 77°C explosive vapour/air mixtures may be formed.	Above 77°C closed system, 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.	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.	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 take to a doctor.
Ingestion	Burning sensation. Sore throat. Nausea. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: complete protective clothing including self-contained breathing apparatus.)	T Symbol R: 45-46-60-25-48/20/22-52/53 S: 53-45-61 Note: E UN Hazard Class: 6.1 UN Pack Group: III	Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

EMERGENCY RESPONSE	STORAGE
Transport Emergency Card: TEC (R)-61GT1-III NFPA Code: H2; F1; R1	Separated from food and feedstuffs, metals such as aluminium or magnesium. Well closed.

IMPORTANT DATA

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

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

Chemical dangers
The substance decomposes on heating above the boiling point and on burning producing toxic fumes including hydrogen bromide, hydrogen chloride. Reacts with aluminium, magnesium, tin and their alloys in presence of water. Attacks some forms of rubber and coatings.

Occupational exposure limits
TLV not established.
MAK: skin absorption; Carcinogen category: 2; Germ cell mutagen group: 2; (DFG 2002).

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, the skin and the respiratory tract. The substance may cause effects on the central nervous system and kidneys, resulting 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, resulting in impaired functions and tissue lesions. This substance is possibly carcinogenic to humans. Causes toxicity to human reproduction or development.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point (decomposes): 196°C Melting point: 6.7°C Relative density (water = 1): 2.1 Solubility in water: poor Vapour pressure, kPa at 20°C: 0.1 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01 Flash point: 77°C Octanol/water partition coefficient as log Pow: 2.96	The substance is harmful to aquatic organisms.

NOTES

Depending on the degree of exposure, periodic medical examination is indicated.
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.
