Fire
Fighting Media and Instructions:
Stannic
oxide is reduced by potassium or sodium at gentle heat and the reaction is
accompanied by incandescence. On heating stannic oxide at 300 deg. C, oxidation
proceeds incandescently. Stannic oxide ignites in nitrous oxide at 400 deg. C
and incandesces when heated in sulfur dioxide.

Section
6: Accidental Release Measures
Small
Spill:Use appropriate
tools to put the spilled solid in a convenient waste disposal container. Finish
cleaning by spreading water on the contaminated surface and dispose of according
to local and regional authority requirements.
Large
Spill:Use a shovel to put
the material into a convenient waste disposal container. Finish cleaning by
spreading water on the contaminated surface and allow to evacuate through the
sanitary system. Be careful that the product is not present at a concentration
level above TLV. Check TLV on the MSDS and with local authorities.
Section
7: Handling and Storage
Precautions:Do
not ingest. Do not breathe dust. Wear suitable protective clothing. In case of
insufficient ventilation, wear suitable respiratory equipment. If ingested, seek
medical advice immediately and show the container or the label. Keep away from
incompatibles such as oxidizing agents.
Storage:
Keep container tightly
closed. Keep container in a cool, well-ventilated area.
Section
8: Exposure Controls/Personal Protection
Engineering
Controls:Use process
enclosures, local exhaust ventilation, or other engineering controls to keep
airborne levels below recommended exposure limits. If user operations generate
dust, fume or mist, use ventilation to keep exposure to airborne contaminants
below the exposure limit.
Personal
Protection: Safety
glasses. Lab coat. Dust respirator. Be sure to use an approved/certified
respirator or equivalent.
Gloves.
Personal
Protection in Case of a Large Spill:Splash
goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing
apparatus should be used to avoid inhalation of the product. Suggested
protective clothing might not be sufficient; consult a specialist BEFORE
handling this product.
Exposure
Limits:TWA: 2 (mg(Sn)/m)
from ACGIH (TLV) [United States] Consult local authorities for acceptable

Special
Remarks on other Toxic Effects on Humans:
Acute
Potential Health Effects: Skin: May cause skin irritation. Eyes: May cause eye
irritation. Inhalation: Although poorly absorbed when inhaled, Inhalation of
dust/fumes may cause nausea, vomiting diarrhea, respiratory tract irritation,
stannosis or benign pneumocoiosis, dyspnea (breathing difficulty, decreased
pulmonary function. Inhalation of fumes may also cause metal fume fever, which
is characterized by flu-like symptoms such as metallic taste, fever, chills,
cough, weakness, chest pain, muscle pain, and increased white blood cell count.
Ingestion: There is as low toxicological risk generally associated with
inorganic tin compound ingestion due largely to the low degree of absorption,
low tissue retention, and rapid turnover of the element. Ingestion of large
amounts may cause gastrointestinal tract irritation, nausea, cramps, vomiting,
diarrhea. It may interfere with various enzyme systems. Inorganic tin salts may
affect the central nervous system, heart, liver. Chronic Potential Health
Effects: Inhalation: Beign pneumoconiosis (stannosis), dyspnea, or decreased
pulmonary may occur following chronic inhalation exposure.
