|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Highly flammable if powdered. Finely dispersed particles form explosive mixtures in air.||NO open flames, NO sparks and NO smoking. NO contact with hot surfaces. Do NOT expose to friction or shock. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.||Use special powder, dry sand. NO other agents. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.|
|PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Cough. See Notes.||Use closed system and ventilation.||Fresh air, rest.|
|Skin||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse and then wash skin with water and soap. Use radiation detector to ensure no remaining contamination.|
|Eyes||Redness.||Wear face shield or eye protection in combination with breathing protection.||Rinse with plenty of water for several minutes (remove contact lenses if easily possible).|
|Ingestion||Do not eat, drink, or smoke during work.||Rinse mouth.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations.||

|OCCUPATIONAL EXPOSURE LIMITS|
|This material and its decay products are radioactive.
Depending on degree of exposure, estimation of dose received may be required by whole body counting techniques.
Depending on the degree of exposure, periodic medical examination is suggested.
Storage in a poorly ventilated area may result in a buildup of gaseous radioactive decay products.
Prolonged retention in the body leads to long term alpha-irradiation of the tissues.
Refer for medical attention if breathing difficulties and/or fever develop.
Do NOT take working clothes home.
