   artificial respiration. If breathing is difficult, give oxygen.



AFTER EYE CONTACT

   Assure adequate flushing of the eyes by separating the eyelids

   with fingers.



AFTER INGESTION

   If swallowed, wash out mouth with water provided person is

   conscious. Call a physician.

EXTINGUISHING MEDIA

   Suitable: Noncombustible. Use extinguishing media appropriate to

   surrounding fire conditions.



SPECIAL RISKS

   Specific Hazard(s): Emits toxic fumes under fire conditions.

SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS

   Wear self-contained breathing apparatus and protective clothing

   to prevent contact with skin and eyes.



6 - Accidental Release Measures



PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL

   Evacuate area.



PROCEDURE(S) OF PERSONAL PRECAUTION(S)

   Wear self-contained breathing apparatus, rubber boots, and heavy

   rubber gloves. Wear disposable coveralls and discard them after

   use.



METHODS FOR CLEANING UP

   Sweep up, place in a bag and hold for waste disposal. Avoid

   raising dust. Ventilate area and wash spill site after material

   pickup is complete.



7 - Handling and Storage



HANDLING

   Directions for Safe Handling: Do not breathe dust. Do not get in

   eyes, on skin, on clothing. Avoid prolonged or repeated exposure.

   Conditions to Avoid: Moisture.



HAZARDOUS DECOMPOSITION PRODUCTS

   Hazardous Decomposition Products: Hydrogen fluoride, Tin/tin

   oxides.



11 - Toxicological Information



SIGNS AND SYMPTOMS OF EXPOSURE

   Symptoms of fluoride overexposure may include salivation,

   nausea, vomiting, abdominal pain, fever, and labored breathing.

   Fluoride ion can reduce serum calcium levels possibly causing

   fatal hypocalcemia. Prolonged exposure to fluoride dusts,

   vapors, or mists results in perforation of the nasal septum.

   Chronic effects include excessive calcification of the bones,

   ligaments, and tendons. Symptoms of exposure may include burning

   sensation, coughing, wheezing, laryngitis, shortness of breath,

   headache, nausea, and vomiting. To the best of our knowledge,

   the chemical, physical, and toxicological properties have not

   been thoroughly investigated.



ROUTE OF EXPOSURE

   Multiple Routes: Harmful if swallowed, inhaled, or absorbed

   through skin. High concentrations are extremely destructive to

   tissues of the mucous membranes and upper respiratory tract,

   eyes, and skin.



12 - Ecological Information



No data available.



13 - Disposal Considerations



SUBSTANCE DISPOSAL

   The material should be dissolved in: 1) water, 2) acid solution,

   or 3) oxidized to a water-soluble state. Precipitate the material

   as the sulfide, adjusting the pH of the solution to 7 to complete

   precipitation. Filter the insolubles and dispose of them in a

   hazardous waste site. Destroy any excess sulfide with sodium

   hypochlorite. Neutralize the solution before flushing down the

   drain. Observe all federal, state, and local environmental

   regulations.
