IV. FIRE AND EXPLOSION HAZARDS DATA


Autoignition Temperature (Powder): 630 oC (cloud), 430 oC (layer)

Flash Point (Method Used): N/E or N/A

Flammable Limits: Upper: N/A                Lower: N/A

Flammability: Flammable solid


Extinguishing Media: If involved in fire, do not use water, CO2 or halogenated extinguishers. Use dry chemical extinguishing agents, graphite, sodium chloride, dry sand or dry ground dolomite.

Special Fire Fighting Procedures: May be flammable in fine powdered form. Use normal firefighting procedures which include wearing NIOSH/MSHA approved self-contained breathing apparatus, flame and chemical resistant clothing; hats, boots and gloves. If without risk, remove material from fire area. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.

Unusual Fire & Explosion Hazard: Combustible in the form of dust when exposed to heat or by spontaneous chemical reaction with Br2, BrF3, Cl2, ClF3, Cu(NO3), K2O2 and S. Powder oxidizes, especially in the presence of moisture.



V. HEALTH HAZARD INFORMATION



Effects of Exposure:


Tin compounds have variable toxicity. Elemental tin and inorganic tin compounds have toxicity and are poorly absorbed when ingested. Some inorganic tin salts are irritating or can liberate toxic fumes on decomposition. The latter is particularly true of tin halogens. (Sax, Dangerous Properties of Industrial Materials, eighth edition.)


Acute Effects:


Inhalation: May cause irritation of the upper respiratory system, metal fume fever, thirst, metallic taste, coughing, fever, chills, muscular pain, headache, nausea, vomiting, profuse sweating, excessive urination and diarrhea.

Ingestion: Poor absorption makes it relatively non-toxic.

Skin: May cause irritation.

Eye: May cause irritation.


Chronic Effects:


Inhalation: May cause pneumonoconiosis and tin poisoning.

Ingestion: Repeated or high levels may cause abdominal pain, nausea, constipation or diarrhea, gastric irritation and loss of weight.

Skin: May cause dermatitis.

Eye: May cause conjunctivitis.


Routes of Entry: Inhalation, ingestion, skin, eyes.

Target Organs: May affect the respiratory system, skin and eyes.

Medical Conditions, if any, Aggravated by the Chemical: None known.

Carcinogenicity: NTP: No           IARC: No          OSHA: No         EPA: No


EMERGENCY AND FIRST AID PROCEDURES:


INHALATION: Move the exposed person to fresh air at once. Keep warm and at rest. If breathing has stopped, perform artificial respiration. Seek medical attention immediately.

INGESTION: Vomiting may occur, but permanent injury is unlikely. If person is conscious, give large quantities of water to drink and induce vomiting. Get medical attention as soon as possible.

SKIN: Remove contaminated clothing form affected area. Brush material off skin, wash with mild soap and water. Seek medical attention if symptoms persist.

EYES: Flush eyes immediately with large amounts of water, lifting the lower and upper lids occasionally. If irritation persists, consult a physician.



VI. REACTIVITY DATA


Stability: Stable

Conditions to Avoid: None

Incompatibility (Material to Avoid): Carbon tetrachloride + water, disulfur dichloride, bromide, bromine trifluoride, chlorine trifluoride, chlorine, iodine bromide, copper (II) nitrate, fluorine, iodine heptafluoride, ammonium nitrate, potassium dioxide, sodium peroxide, sulfur, tellurium, molten tin + water. Concentrated acids, oxidants. Fires and explosions can occur when metallic tin is in contact with turpentine.


Hazardous Decomposition Products: Tin oxides.

Hazardous Polymerization: Will not occur.



VII. SPILL OR LEAK PROCEDURES


Steps to be Taken in Case Material is Released or Spilled: Wearing full protective equipment, described in section VIII, isolate spill area, provide ventilation and extinguish sources of ignition. Scoop or vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust. Use non-sparking tools.

Waste Disposal Method: Dispose of in accordance with Local, State and Federal waste disposal regulations.



VIII. SPECIAL PROTECTION INFORMATION



Respiratory Protection (Specify Type): NIOSH/MSHA approved high efficiency particle respirator.

Ventilation: Use local exhaust to maintain concentration at or below PEL, TLV. Mechanical exhaust is not recommended. When working with powders, handle in a controlled and enclosed process in an inert atmosphere.

Protective Gloves: Rubber gloves.

Eye Protection: ANSI approved safety glasses. When working with powder form do not wear contact lenses.

Other Protective Equipment: Chemical resistant coveralls, lab coat or apron.



IX. SPECIAL PRECAUTIONS


Precautions to Be Taken in Handling and Storage: Avoid dust generation. Avoid breathing dust or fume. Keep container tightly closed. Store in a cool (-18 to 38 oC), dry, well-ventilated area. Wash thoroughly after handling.

Other Precautions: Tin powder oxidizes in moisture. Handle and store in a dry, controlled atmosphere.

Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Shower and change clothes at the end of work shift. Do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
