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.

Special Remarks on Fire Hazards:

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.

Special Remarks on Explosion Hazards: Not available.

 

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 exposure limits.

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.
