| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Highly flammable.
|
NO open flames, NO sparks, and NO smoking. NO contact with hot surfaces.
|
Special powder, dry sand, NO other agents.
|
| EXPLOSION |
Finely dispersed particles form explosive mixtures in air.
|
Do NOT expose to friction or shock. Prevent deposition of dust; closed system, dust explosion-protected electrical equipment and lighting.
|
In case of fire: keep drums, etc. cool by spraying with water but NO direct contact with water.
|
| EXPOSURE |
|
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!
|
IN ALL CASES CONSULT A DOCTOR!
|
| Inhalation |
Cough ; symptoms of delayed effects: see Notes.
|
Closed system and ventilation.
|
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
|
| Skin |
Redness. Roughness.
|
Protective gloves, protective clothing.
|
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. Use radiation detector to ensure no remaining contamination.
|
| Eyes |
Redness. Pain.
|
Face shield or eye protection in combination with breathing protection.
|
|
| Ingestion |
Symptoms of delayed effects: see Notes.
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. induce vomiting (ONLY IN CONSCIOUS PERSONS!) Refer for medical attention.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: GREYISH-WHITE, LUSTROUS METAL; SOLID IN VARIOUS FORMS. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. CHEMICAL DANGERS: Heating may cause violent combustion or explosion. May explosively decompose on shock, friction, or concussion. On combustion, forms toxic fumes. Reacts violently with strong oxidants causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV not established |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin, and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes, the skin and the respiratory tract. Inhalation of the vapour or aerosol may cause damage to the bone and lung. The substance may cause effects on the blood forming system, resulting in pernicious anaemia. The effects may be delayed (see Notes). Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. Risk of affection of the lungs upon repeated or prolonged exposure to the dust. This substance is carcinogenic to humans. May cause heritable genetic damage. May cause birth defects. | ||

| NOTES | |||
|
Depending on degree of exposure, estimation of dose received may be required by whole body counting technics. Depending on the degree of exposure, periodic medical examination is suggested. This material and its decay products are radioactive. 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. May result in changes in the blood-forming, nervous and reticulo-endothelial systems, and functional and morphological damage to lung and bone. Do NOT take working clothes home. Card has been partly updated in October 2005. See section Emergency Response.
