TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Explosive. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames, NO sparks, and NO smoking.	Water in large amounts. Powder, carbon dioxide
EXPLOSION	Risk of explosion.	Do NOT expose to friction or shock. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.	Combat fire from a sheltered position. In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		STRICT HYGIENE!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Weakness. Dizziness. Headache. Nausea. Convulsions. Unconsciousness.	Closed system and ventilation.	Fresh air, rest. Refer for medical attention.
Skin		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	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	(see Inhalation).	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Do NOT induce vomiting. Give a slurry of activated charcoal in water to drink. Refer immediately for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING

Routes of exposure
The substance can be absorbed into the body in hazardous amounts by inhalation and by ingestion.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly.

Effects of short-term exposure
The substance may cause effects on the central nervous system, resulting in irritability, insomnia, convulsions and unconsciousness.

Effects of long-term or repeated exposure
The substance may have effects on the central nervous system. Repeated or prolonged contact with skin may cause dermatitis.
