Section 3: Hazard Identification

Emergency overview:

       Special Hazard Precautions: 
             In some states of this material, it can be extremely flammable, 
             may be pyrophoric. It is radioactive.

       Acute:  
             Kidney damage, arterial lesions and possible liver effects. 
             May irritate eyes and skin.  Toxic if inhaled.  Irritating to 
             lungs. May cause kidney damage.  arterial  lesions, and liver 
             effects.

       Chronic:   
             Dermatitis. Possible carcinogen of lymphatic and blood-forming tissue.


Signal Word

       Harmful!

Physical Health Hazards:
       Harmful by inhalation, in contact with the skin and if swallowed.


Personal protection:
       Wear approved protective clothing when working with this material
       in order to avoid any contact with material at all.  Long sleeves
       and/or lab coat are recommended to protect against skin contact.
       Approved chemical goggles are recommended to protect against eye
       contact.    Respiratory Protection: NIOSH/MSHA Approved high
       efficiency particle respirator.   Use rubber gloves for hand 
       protection.

Physical state:
       Solid chunks or fines associated with the chunks

Color:            Dark brown to black chips, with some associated "fines"

Odor:             None

Odor threshold:   No data available



Potential Health Effects:

Routes of exposure 
      Inhalation of the fine powder, skin, eye

Signs and Symptoms of Acute Exposure:

Ingestion:  
      May cause kidney damage and acute necrotic arterial lesions.  
      May also effect liver function.

           Skin:  May cause irritation

           Eye:  May cause irritation

           Inhalation:  Considered toxic by inhalation due to lung
                        irritation from inhaled fine particles from the 
                        "dust" that is always present. May also cause 
                        kidney damage and acute necrotic arterial lesions. 
                        Liver effects might be present as well.


Chronic Health Effects Summary:

           Skin:  May cause dermatological problems.

           
Conditions Aggravated by Exposure:

            None known.

Signs and Symptoms of Overexposure:  

            Precise health hazards are not known. But chronic radiation
            effects are similar to those of ionizing radiation.  It is 
            reported that carcinogenicity is related to dose and exposure 
            time.  Uranium may cause cancer of lymphatic and blood-forming 
            tissues. 



Section 4: First Aid Measures

Take proper precautions to ensure your own health and safety before
attempting to rescue and providing first aid.  For specific information
refer to the Emergency Overview in Section of this MSDS.


Inhalation: No specific information is available, but one should 
contact medical help at once.


Eye Contact:  Wash eyes, including under lids,  with copious amounts 
low-pressure water, for minimum of 15 minutes, removing contact lenses if
possible.  Then seek medical advice from a qualified physician.

Skin Contact:  Remove contaminated clothing, then rinse skin thorough 
with large amounts of soap and water to remove all traces of the substance. 
If irritation persists, contact qualified medical assistance.

Ingestion:  Adverse health effects due to ingestion are to be expected,
but exactly what are these health effects are not known. Wash out mouth with 
water but never give liquids to an unconscious person. Call a physician at 
once and seek other medical attention.



Section 5: Fire Fighting Measures

      

NFPA Rating:  Not known

Flammability classification:

         Not known.

Flash Point/Method:   Not applicable

Auto-Ignition Temperature:  Not known

Flammable Limits:  Lower:   Not applicable
                   Upper:   Not applicable


Hazardous Combustion Products:

         Not known.


Special Conditions to Avoid:

         None specifically known.


Extinguishing Media:

         Fires:  Material is flammable and may be pyrophoric.  Do not use
                 water, use dry chemical extinguishing agents.


Fire Fighting Instructions:

         Protective Equipment/Clothing:  Wear a NIOSH approved positive
         pressure self-contained breathing apparatus and firefighter
         turnout gear.  Wear long sleeves and chemical goggles for eye
         protection.

         Instructions:  Use flooding quantities of water until well after
         fire is out.  If the product now wet with water starts to migrate
         to other areas or even to the outside environment, dike it at once
         to prevent that from happening.  Keep moist to prevent a dust
         hazard from starting.

         Material could be spontaneously flammable in air, remove material
         form the area of the fire if without risk.





Section 6: Accidental Release Measures

      
Release response:
         Wear NIOSH approved respirator, chemical safety goggles,
         rubber boots, and heavy rubber gloves.  Sweep up wet product,
         place in a bag and hold for waste disposal.  If product is
         tending to flow away from fire or spill area, try to dike the
         material to keep in one place.  If a broom is used, remember
         that the broom, when dried out, will contain powder of the
         product and if the broom is put into continued use without proper
         cleaning, then a hazardous dust cloud could be created.  Ventilate
         area and wash spill site after pick up is complete.

Reportable Quantities:  
       See Section 15:  Regulatory information.




Section 7: Handling and Storage

Handling:

Use full protective gear as described above.    
Respiratory Protection: NIOSH/MSHA Approved high efficiency particle
respirator.

Storage:

Keep container dry.  Store away from excessive heat. Keep container 
closed to prevent contamination.



Section 8: Exposure Controls and Personal Protection



Engineering Controls:  If user operations generate dust or fumes,
ventilate area to prevent accumulation.


Personal Protection:

    Inhalation:  Use appropriate respiratory protection at all times. 
                 If product is to be used as part of a vacuum deposition 
                 process, we would recommend that all vacuum pumps be 
                 vented to the outdoors, in order to avoid any possible 
                 release of uranium compounds into the laboratory environment.  
                 Respiratory Protection: NIOSH/MSHA Approved high efficiency
                 particle respirator.

    Skin:        Protective clothing such as long sleeves or a lab coat should 
                 always be worn.   

    Eye:         Always use chemical goggles, even for work with small quantities, 
                 such as the loading of a tungsten basket or boat prior to making 
                 a deposition of the material.  Chunks can be handled with a pair 
                 of fine tweezers, the best being a Style #5.
