Flash Point (Method used): N/A Autoignition Temperature: N/A
Explosive Lim its: Lower: N/A Upper: N/A
Extingu ishing Media: Special powder for m etal fires. Do not use water or halogen ated extinguisher.
Special Firefighting Procedures: Firefighters m ust w ear fu ll face, self-con tained breathing apparatus with full pro tective clothing to
prevent contac t with skin an d eyes.
Unusual Fire and Explosion Hazards: Do not use water near molten metal, a danger of explosion exists. At very high temperatures
toxic metal oxide fumes may be evolved.
V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of indium-tin alloy have not been
thoroughly investigated and reported. Exposure to indium compounds may cause pain in the joints and bones, tooth decay, nervous
and gastrointestinal disorders, heart pain and general debility. Experiments with animals also indicate that indium may cause reduced
food and water consumption with weight loss, pulmonary edema, pneumonia, blood, liver and kidney damage, leg paralysis and
dam age to the b rain, heart, ad renals and spleen .
Metallic tin and inorg anic tin com pounds m ay cau se nause a, vom iting, diarrhea, irritation and pneum ocon iosis.
Carcino genicity: NTP: No IARC: No OSHA: No
EMERG ENCY AND FIRST AID PROCEDURES:
INHALATION: Remove from exposure, seek imm ediate medical attention.
INGESTION: Remove from exposure, seek imm ediate medical attention.
SK IN: Remov e any contam inated clothing, brush material off of skin, flush with running water, wash carefully with soap and water.
EYE: Flush with copious amounts of water for 15 minutes. Seek imm ediate medical attention.

VII SPILL OR LEAK PROC EDURES
Steps to Be Taken in Case Material Is Released or Spilled: We ar appropriate respilratory and protective equipm ent specified in
section VIII. Isolate sp ill area an d provid e ven tilation. Scoo p or vacu um up u sing a high efficien cy particulate absolute (HE PA ) air
filter and place in a closed container for proper disposal. Do not allow material to be released to the environment without proper
governm ental perm its.
Waste Disposal Method: Dispose o f in accord ance w ith applicable Federa l, State and L ocal Regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: Use su itable respirato r wh en high conc entrations are pre sent.
Ventilation: Use local exhaust to maintain concentration at low levels. Mechanical is recommended.
Protective Gloves: Impe rvious g loves.
Eye Protection: Safety go ggles.
Other Protective Equipment: Protective work clothing.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in cool, dry conditions in well sealed containers. Be su re solid alloy is
dry befo re adding to m olten alloy. Avoid m aking du st.
Wo rk 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. Do not
blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and
facilities for washing.
