TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible under specific conditions. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Water spray, foam, powder, carbon dioxide.
EXPLOSION	Risk of fire and explosion if formulations contain flammable/explosive solvents.

EXPOSURE		PREVENT DISPERSION OF DUST!
•INHALATION		Ventilation (not if powder).	Fresh air, rest.
•SKIN		Protective gloves.	Rinse and then wash skin with water and soap.
•EYES	Redness. Pain.	Safety spectacles .	Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
•INGESTION		Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.
