TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible.	NO open flames. NO contact with acid(s) and base(s).	Water spray, carbon dioxide.
EXPLOSION	Above 76°C explosive vapour/air mixtures may be formed.	Above 76°C use a closed system, ventilation.	In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.

EXPOSURE		PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
INHALATION	Dizziness. Drowsiness. Unconsciousness. Vomiting.	Local exhaust or breathing protection.	Fresh air, rest.
SKIN	MAY BE ABSORBED! Redness. Skin burns.	Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
EYES	Redness. Pain. Severe deep burns.	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 take to a doctor.
INGESTION	Abdominal pain. Burning sensation. Diarrhoea. Nausea. Shock or collapse (further see Inhalation).	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.
