* Description of first aid measures
- General advice : First Aid responders should pay attention to self-protection and use the recommended protective clothing. Take off contaminated clothing and shoes immediately.
Move out of dangerous area. Keep warm and in a quiet place.
- If inhaled : Provide fresh air. If not breathing, give artificial respiration. Keep the victim calm and in a semi-upright position. Call a physician immediately.
- In case of skin contact : Wash off immediately with plenty of water for at least 15 minutes. Consult a physician.
- In case of eye contact : Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Call a physician immediately.
- If swallowed : Clean mouth with water and drink afterwards plenty of water. Never give anything by mouth to an unconscious person. Do NOT induce vomiting. Call a physician immediately.
• Most important symptoms and effects, both acute and delayed
- Symptoms : Respiratory disorders. Irritation
•Indication of any immediate medical attention and special treatment needed
- Treatment : Treat symptomatically. For specialist advice physicians should contact the Poisons. Information Service.

Fire-fighting measures
•Extinguishing media
-Suitable extinguishing media : Dry extinguishing media based on NaCl or pulverized limestone.
-Unsuitable extinguishing media: Water, Halons, Carbon dioxide (CO2)
•Special hazards arising from the substance or mixture
-Specific hazards during firefighting: Heat generation can lead to spontaneous combustion. Dust can form an explosive mixture in air. Burning product decomposes water instantaneously (explosion). May form toxic gases on heating or in case of fire. Hydrogen. Zirconium dioxide
•Advice for firefighters
-Special protective equipment for firefighters: Wear full protective clothing and self-contained breathing apparatus.
-Further information : Use a water spray to cool fully closed containers. Collect contaminated fire extinguishing water separately. This must not be discharged into drains. Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

Handling and storage
•Precautions for safe handling
-Advice on safe handling : Handle under inert gas. Keep under argon. Provide sufficient air exchange and/or exhaust in work rooms. Wear personal protective equipment. Avoid dust formation. Handle in accordance with good industrial hygiene and safety practice. In general, emissions are controlled and prevented by implementing an appropriate management system, including regular informing and training workers.
-Advice on protection against fire and explosion: Keep away from sources of ignition - No smoking. Take precautionary measures against static discharges. Dust can form an explosive mixture in air. Take precautions against dust explosion. Use explosion-proof equipment. Heat generation can lead to spontaneous combustion.
•Conditions for safe storage, including any incompatibilities
-Requirements for storage areas and containers: Keep under argon. Keep containers tightly closed in a dry, cool and wellventilated place. Keep away from heat. Protect from moisture. Avoid contact with air/oxygen.
-Further information on storage conditions: Product is hygroscopic.
-Advice on common storage : Never allow product to get in contact with water during storage. Do not store near acids. Incompatible with oxidizing agents.
•Specific end use(s)
-Specific use(s) : Reducing agents, Alloy component., Pyrotechnics., Getter technology
