Types of Hazard/ Exposure	Acute Hazards/ Symptoms	Prevention	First Aid/ Fire Fighting
FIRE	Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings: use appropriate extinguishing media.
Explosion

Exposure		PREVENT DISPERSION OF DUST! AVOID Exposure OF ADOLESCENTS AND CHILDREN!
•Inhalation	Cough. Sore throat.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
•Skin	Redness. Pain.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
•Eyes	Redness. Pain. Blurred vision.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•Ingestion	Nausea. Vomiting. Weakness. Convulsions.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.
