V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

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

Lead and lead compounds may cause abdominal pain, diarrhea, loss of appetite, metallic taste, nausea, vomiting, lassitude, insomnia, muscle weakness, joint and muscle pain, irritability, headache and dizziness.  Red blood cells may be damaged resulting in anemia.  Gastritis and injury to the kidneys, liver, male gonads, and central nervous system may also occur.

Metallic tin and inorganic tin compounds may cause nausea, vomiting, diarrhea, irritation and pneumoconiosis.

Acute Effects:

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

Ingestion:  May cause constipation and abdominal pain, colic, tremors, nausea, vomiting, diarrhea, metallic taste, loss of appetite, irritability and muscle pain.  May cause acute lead toxicity.

Skin:  May cause irritation.

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  May cause pneumonoconiosis and tin poisoning.  May cause chronic lead toxicity.  May be toxic to the central and peripheral nervous system affecting the cerebellum, spinal cord, motor and sensory nerves.

Ingestion:  Repeated or high levels may cause abdominal pain, nausea, constipation or diarrhea, gastric irritation and loss of weight. May cause anemia, gingival lead line, paralysis in the wrist and permanent neurological injury.  May cause chronic lead toxicity.  May cause nephritis, scarring and shrinking of the kidney tissue. 

Skin:  May cause dermatitis.

Eye:  May cause conjunctivitis.

Target Organs:  May affect the respiratory system, gastrointestinal tract, central nervous system, kidneys, blood, skin, gingival tissue and eyes. 

Medical Conditions, if any, Aggravated by the Chemical:  Pre-existing lung and circulatory disorders.

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

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and seek medical attention immediately.

INGESTION:  Give 1-2 glasses of milk or water and induce vomiting; seek medical attention immediately.  Never induce vomiting or give anything by mouth to an unconscious person.

SKIN:  Remove any contaminated clothing, brush material off of skin, wash affected area with mild soap and  water; seek medical attention if symptoms persist.

EYES:  Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek medical attention if symptoms persist.

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  None 

Incompatibility (Material to Avoid):  Oxidizing agents, acids, interhalogens.

Hazardous Decomposition Products:  Lead oxide fumes.

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.

Protective Gloves:  Rubber gloves.

Eye Protection:  Safety glasses.

Other Protective Clothing or Equipment:  Protective gear suitable to prevent contamination.

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, dry, well-ventilated area.  Wash thoroughly after handling.

Other Precautions:  Do not store together with oxidizing or acidic materials.

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.
