	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Heating will cause rise in pressure with risk of bursting. Above 43°C explosive vapour/air mixtures may be formed.	NO open flames, NO sparks and NO smoking. Above 43°C use a closed system, ventilation and explosion-proof electrical equipment.	Use alcohol-resistant foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT GENERATION OF MISTS!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Headache. Nausea. Dizziness. Drowsiness. Unconsciousness.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Seek medical attention if you feel unwell.
Eyes	Redness. Pain. Temporary loss of vision.	Wear safety goggles or eye protection in combination with breathing protection.	Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
Ingestion	Abdominal pain. Burning sensation in the throat and chest. Further see Inhalation.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Remove all ignition sources. Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria WARNING Flammable liquid and vapour May be harmful if swallowed or in contact with skin Causes skin and 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
STORAGE
Fireproof. Separated from strong oxidants.

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, skin and respiratory tract. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis. The substance may cause effects on the central nervous system. Exposure at high levels could cause lowering of consciousness.	Inhalation risk A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis.
