	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Above 42°C explosive vapour/air mixtures may be formed.	NO open flames, NO sparks and NO smoking. Above 42°C use a closed system, ventilation and explosion-proof electrical equipment.	Use water spray, alcohol-resistant foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Burning sensation.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Dry skin. Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Wear safety spectacles, face shield 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	Abdominal pain. Headache. Drowsiness. Weakness. Nausea. Vomiting. Unconsciousness.	Do not eat, drink, or smoke during work.	Rinse mouth. Give nothing to drink. Do NOT induce vomiting. Refer immediately for medical attention.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: protective clothing, safety goggles and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable non-plastic containers as far as possible. Absorb liquid in sand or inert absorbent. Wash away remainder with plenty of water.	According to UN GHS Criteria WARNING Flammable liquid and vapour Harmful if swallowed Causes serious eye irritation May cause respiratory irritation May cause drowsiness or dizziness May be harmful if swallowed and enters airways Transportation UN Classification UN Hazard Class: 3; UN Pack Group: III

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure The substance is severely irritating to the eyes. The substance is irritating to the respiratory tract. The substance is mildly irritating to the skin. Ingestion could cause effects on the central nervous system. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis.	Inhalation risk A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure The substance defats the skin, which may cause dryness or cracking.
