	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive.	NO open flames, NO sparks and NO smoking. Do NOT expose to heat, friction or shock.	Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

AVOID ALL CONTACT!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Dizziness. Drowsiness.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	MAY BE ABSORBED! Redness. See Inhalation.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Seek medical attention if you feel unwell.
Eyes	Redness. Pain.	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 Inhalation.	Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. 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 DANGER Highly flammable liquid and vapour Causes skin and eye irritation May cause respiratory irritation May cause drowsiness or dizziness Suspected of causing cancer May damage fertility or the unborn child May cause damage to nervous system through prolonged or repeated exposure Harmful to aquatic life Transportation UN Classification UN Hazard Class: 3; UN Pack Group: II
STORAGE
Fireproof. Well closed. Separated from strong oxidants and strong bases. Store in an area without drain or sewer access. Ventilation along the floor.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID. Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. This generates fire and explosion hazard. Chemical dangers Decomposes on burning. This produces toxic gases including hydrogen bromide. Reacts with strong bases and strong oxidants.

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. This may result in 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 central nervous system and peripheral nervous system. This may result in impaired functions. This substance is possibly carcinogenic to humans. May cause toxicity to human reproduction or development.
