HEALTH HAZARDS (ACUTE AND CHRONIC)

To the best of our knowledge the chemical, physical and toxicological properties
of uranium oxide have not been thoroughly investigated and recorded.

Uranium is a highly toxic element on an acute basis. The permissible levels for
soluble compounds are based on chemical toxicity, while the permissible body
level for insoluble compounds is based on radio-toxicity. The high chemical
toxicity of uranium and its salts is largely shown in kidney damage which may
not be reversible. Acute arterial lesions may occur after acute exposures. The
high toxicity effect of insoluble compounds is largely due to lung irradiation
by inhaled particles. (Sax, Dangerous Properties of Industrial Materials, eighth
edition)

URANIUM SALTS CAUSE HARMFUL EFFECTS CHEMICALLY AND RADIOLOGICALLY.

INHALATION:

Acute: May cause acute arterial lesions.

Chronic: May cause kidney damage.

INGESTION:

Acute: May cause nausea and vomiting.

Chronic: No chronic health effects recorded.

SKIN:

Acute: May cause irritation.

Chronic: May cause dermatitis.

EYE:

Acute: May cause irritation.

Chronic: Studies indicate probability of cataracts.

TARGET ORGANS: May affect the lymphatics, kidneys, skin, and bone marrow.

CARCINOGENITICY: NTP? No, IARC Monographs? No, OSHA Regulated? No

CARCINOGENICITY/OTHER INFORMATION

No data available.

RECOMMENDED EXPOSURE LIMITS: See “Section II” LD 50/LC 50: No toxicity data
recorded

SIGNS AND SYMPTOMS OF EXPOSURE

INHALATION: May cause shortness of breath, coughing and changes in the blood.

INGESTION: May cause nausea, vomiting, changes in the blood and urine.

SKIN: May cause redness, itching, burning sensation and inflammation.

EYE: May cause redness, itching, burning, watering and inflammation.

MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE

Pre-existing respiratory and skin disorders.

EMERGENCY AND FIRST AID PROCEDURES

INHALATION: Remove victim to fresh air; keep warm and quiet; give oxygen if
breathing is difficult and seek medical attention immediately.

INGESTION: Give 1-2 glasses of milk or water and induce vomiting; seek medical
attention. Never induce vomiting or give anything by mouth to an unconscious
person.

SKIN: Remove contaminated clothing; brush material off skin; wash affected area
with mild soap and water; check for radioactive contamination; seek medical
attention.

EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at
least 15 minutes. Seek medical attention immediately.

NOTE TO PHYSICIAN

No data available.

SECTION VII – PRECAUTIONS FOR SAFE HANDLING AND USE

Uranium oxide, powder

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED

Wear appropriate respiratory and protective equipment specified in section
VIII-control measures. Isolate spill area, provide ventilation and extinguish
sources of ignition. Vacuum up spill using a high efficiency particulate
absolute (HEPA) air filter and place in a closed container for proper disposal.
Use non-sparking tools. Take care not to raise dust.

WASTE DISPOSAL METHOD

Dispose of in accordance with local, state and federal regulations.

HAZARD LABEL INFORMATION: Store in cool, dry area Store in tightly sealed
container

Wash thoroughly after handling Store in an inert atmosphere

PRECAUTIONS TO BE TAKEN IN HANDLING

Radioactive: Store away from radiation sensitive equipment and devices.

PRECAUTIONS TO BE TAKEN IN STORING

No data available.

OTHER PRECAUTIONS

Uranium oxide ignites spontaneously in air and water. Handle and store in an
inert gas.
