TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, water spray, foam, carbon dioxide.
EXPLOSION	Above 74°C explosive vapour/air mixtures may be formed.	Above 74°C closed system, ventilation.

EXPOSURE		PREVENT GENERATION OF MISTS!
INHALATION	Shortness of breath.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration if indicated, and refer for medical attention.
SKIN	Redness. Pain.	Protective gloves, protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower, and refer for medical attention.
EYES	Redness, pain.	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		Do not eat, drink, or smoke during work.	Rinse mouth, and refer for medical attention.
