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:  If symptoms are experienced, move victim to fresh
             air, and obtain medical attention.

Eye Contact:  Wash eyes with copious amounts low-pressure water,
              removing contact lenses if possible.  Then seek medical advice
              from a qualified physician.

Skin Contact:  Remove contaminated clothing, then rinse skin thorough
               with soap and water to remove all traces of the substance.

               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:

         Selenium and selenium oxides.  One can also expect the emission
         of other toxic fumes under fire conditions.

Special Conditions to Avoid:

         Strong oxidizing agents, moisture, oxygen/air, strong acids

Extinguishing Media:

         Fires:  Use dry chemicals, CO2, water spray, or appropriate foam.

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.




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.

Storage:       Keep container dry.  Store away from excessive heat
and away from strong oxidizing agents and moisture.  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 Se compounds into the laboratory
environment.

    Skin:  Protective clothing such as long sleeves or a lab coat
should always be worn.   When handling heated materials, also be sure
to use heat-resistant gloves, boots and chemical goggles.

    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.
