TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible.	NO open flames.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION	Above 71°C explosive vapour/air mixtures may be formed. Finely dispersed particles form explosive mixtures in air.	Above 71°C use a closed system, ventilation. Prevent deposition of dust: closed system, dust-explosion proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).

EXPOSURE		PREVENT DISPERSION OF DUST!
•INHALATION	Cough. Sore throat. Burning sensation. Laboured breathing.	Local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Refer for medical attention.
•SKIN	Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES	Redness. Pain. Burns	Safety goggles, or eye protection in combination with breathing protection if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION	Burning sensation in the throat and chest.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Seek medical attention if you feel unwell

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING
