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.	In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION	Risk of fire and 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.

EXPOSURE
Inhalation	Dizziness. Headache.	Ventilation (not if powder), local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin		Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness.	Safety goggles, or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Dizziness. Headache.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: P2 filter respirator for harmful particles. Remove all ignition sources. Cover the spilled material with water. Carefully collect remainder, then remove to safe place. Do NOT wash away into sewer.	E Symbol R: 3 S: (2-)35 UN Hazard Class: 1.1D

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-10G1.1	Fireproof. Separated from strong oxidants. Store in an area without drain or sewer access.

IMPORTANT DATA
