	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. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.	Use powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT GENERATION OF MISTS!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Burning sensation. Headache. Dizziness. Nausea. Vomiting.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness.	Protective gloves.	Rinse skin with plenty of water or shower. Remove contaminated clothes. Refer for medical attention .
Eyes	Pain. Redness.	Wear safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Abdominal cramps. Aspiration hazard! Further see Inhalation.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Remove all ignition sources. Personal protection: protective clothing, protective gloves, safety goggles and filter respirator for organic vapours of low boiling point adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Do NOT wash away into sewer. Collect leaking liquid in sealable containers. Cover the spilled material with inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria DANGER Highly flammable liquid and vapour Harmful if swallowed Causes eye irritation May cause respiratory irritation May be harmful if swallowed and enters airways Harmful to aquatic life Transportation UN Classification UN Hazard Class: 3; UN Pack Group: II
STORAGE
Fireproof. Separated from strong oxidants, strong bases, strong acids and strong reducing agents. Well closed. Store in an area without drain or sewer access.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation, through the skin and by ingestion. Effects of short-term exposure The substance is irritating to the eyes. The substance at very high concentrations is irritating to the upper respiratory tract. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis. Medical observation is indicated. The substance may cause effects on nervous system. Exposure could cause lowering of consciousness.	Inhalation risk No indication can be given whether a harmful concentration in the air will be reached. Effects of long-term or repeated exposure Repeated or chronic inhalation of the vapour may cause chronic inflammation of the upper respiratory tract.
