Types of Hazard/ Exposure	Acute Hazards/ Symptoms	Prevention	First Aid/ Fire Fighting
FIRE	Flammable.	NO open flames, NO sparks, and NO smoking.	Water spray, powder, carbon dioxide.
Explosion	Above 26°C explosive vapour/air mixtures may be formed.	Above 26°C use a closed system, ventilation, and explosion-proof electrical equipment.

Exposure		PREVENT DISPERSION OF DUST!
•Inhalation	Cough.	Avoid inhalation of dust.	Fresh air, rest.
•Skin		Protective gloves.	Rinse skin with plenty of water or shower.
•Eyes	Redness. Pain.	Safety goggles	Rinse with plenty of water (remove contact lenses if easily possible).
•Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth. Give one or two glasses of water to drink.
