	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Above 98°C explosive vapour/air mixtures may be formed.	NO open flames, NO sparks and NO smoking. Above 98°C use a closed system, ventilation and explosion-proof electrical equipment.	Use foam, carbon dioxide, powder.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Dizziness. Headache. Nausea.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Severe deep burns. Pain.	Wear safety goggles 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	Nausea. Vomiting. Dizziness. Drowsiness. Headache. Weakness.	Do not eat, drink, or smoke during work.	Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
