	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings, use appropriate extinguishing media.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Further see Ingestion.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	Redness. See Ingestion.	Protective gloves. Protective clothing.	Rinse and then wash skin with water and soap. Seek medical attention if you feel unwell.
Eyes	Watering of the eyes. Redness. Pain.	Wear safety spectacles or eye protection in combination with breathing protection.	Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion	Headache. Dizziness. Drowsiness.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.	According to UN GHS Criteria WARNING Harmful if swallowed Causes skin and eye irritation May cause respiratory irritation May cause damage to the nervous system and liver May cause damage to liver through prolonged or repeated exposure Harmful to aquatic life with long lasting effects Transportation UN Classification UN Hazard Class: 6.1; UN Pack Group: III
STORAGE

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. TURNS YELLOW ON EXPOSURE TO LIGHT AND AIR. Physical dangers No data. Chemical dangers Decomposes on heating. This produces toxic and corrosive fumes including hydrogen bromide and bromine. Reacts violently with oxidants and bases. Reacts with powdered metals. This generates fire and explosion hazard. Attacks some forms of plastic, rubber and coatings.
