IV.  FIRE AND EXPLOSION HAZARDS DATA

Flash Point:  N/A

Autoignition Temperature:  N/E

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

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.  Do not apply water to burning metal as a violent explosion may result.

V.  HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of tin have not been thoroughly investigated and recorded.

Tin compounds have variable toxicity.  Elemental tin and inorganic tin compounds have low 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)

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. 

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 to fresh air, keep warm and quiet, give oxygen if breathing is difficult, seek medical attention. 

INGESTION:  If conscious, give large quantities of water to drink and induce vomiting.  Get medical attention as soon as possible.  Never induce vomiting or give anything by mouth to an unconscious person.

SKIN:  Remove contaminated clothing from 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:  Heat/overheating, dusting conditions.

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:  NIOSH/MSHA approved high efficiency particle respirator when high concentrations are present.

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 Clothing or 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.
