Section 3: Hazard Identification


Emergency overview:
Highly toxic (USA). Very Toxic (EU). Dangerous for the environment.
Very toxic by inhalation and if swallowed.  Danger of cumulative effects.
Toxic to aquatic organisms; may cause long-term adverse effects in the
aquatic environment.  Radioactive material.

Target Organs: Liver, Kidneys

Potential Health Effects

Eye: Absorption of soluble uranium compounds thorough eye
tissue is reported.

Skin: No information found.

Ingestion: Toxic by ingestion

Inhalation: Moderate hazard on inhalation.  Coughing, sneezing &
breathing difficulty may occur.

Chronic: Damage to Kidneys & Liver may occur after continued exposure.

Section 4: First Aid Measures



Eyes: In case of eye contact, flush eyes with large amounts of water
for at least 15 minutes, occasionally lifting upper and lower eyelids.

Skin: In case of skin contact, wash immediately with plenty
of soap and water.

Ingestion: If person is conscious, wash out mouth with water.
Seek medical attention. 

Inhalation: If inhaled, remove to fresh air.  If breathing
becomes difficult, seek medical attention.

Section 5: Fire Fighting Measures

      

General Information:
Emits toxic fumes under fire conditions. As in any fire, wear
self-contained breathing apparatus pressure-demand (MSHA/NIOSH
approved or equivalent) and full protective gear.


Extinguishing Media:
Water spray, carbon dioxide, dry chemical powder, or appropriate foam.

Section 6: Accidental Release Measures

      

General Information:
Handle as a radioactive spill.

Spills/Leaks:
