Remove victim out of the danger area. Keep affected person warm, stilland covered. Take off immediately all contaminated clothing.

5 In all cases of doubt, or when symptoms persist, seekmedical advice. In case of unconsciousness place person in the recovery position. Never give anything by mouth. If breathing is irregular or stopped, immediately seek medical assistance and start first aid actions. In case of respirat-ory tract irritation, consult a physician. Provide fresh air. Wash with plenty of soap and water. Remove contact lenses, if present and easy to do. Continue rinsing. Irrigate copiously with clean, fresh water for atleast 10 minutes, holding the eyelids apart. Rinse mouth with water (only if the person is conscious). Do NOT induce vomiting. Symptoms and effects are not known to date. none Water spray, Alcohol resistant foam, BC-powder, Carbon dioxide (CO2) Water jet Nitrogen oxides (NOx) In case of fire and/or explosion do not breathe fumes.

6 Co-ordinate firefighting measures to the fire surroundings. Do not allow firefighting water to enter drains or water courses. Collect contaminated firefighting water separately. Fight fire with normal precautions from a reasonable distance.

7 Wear breathing apparatus if exposed to vapors/dust/aerosols/gases. Keep away from drains, surface and ground water. Retain contaminated washing water and dispose of it. Covering of drains Wipe up with absorbent material ( cloth, fleece). Collect spillage: Sawdust, Kieselgur (diatomite), Sand, Universalbinder Use of adsorbent materials. Place in appropriate containers for disposal. Ventilate affected area. Hazardous combustion products: see section 5. Personal precautions: see section 8. Incompatible materials: see sec-tion 10. Disposal considerations: see section 13. Use local and general ventilation. Use only in well-ventilated areas. Wash hands after use. Do not eat, drink and smoke in work areas.

8 Remove contaminated clothing and protectiveequipment before entering eating areas. Never keep food or drink in the vicinity of chemicals. Never place chemicalsin containers that are normally used for food or drink. Keep away from food, drink and animal feedingstuffs. Keep any substance that emits harmful vapors or gases in a place that allows these to be permanently extracted. Only packagings which are approved ( acc. to the Dangerous Goods Regulations) may be used. See section 16 for a general overview.
