V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

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

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 damage to the brain, heart, adrenals and spleen.

Antimony and its compounds are irritating to the skin and mucous membranes and are systemic poisons.  Effects are reported to include a metallic taste in the mouth, vomiting, colic, loss of appetite and weight, and diarrhea.  In addition, dermatitis may result which starts as an inflammation of the hair follicles and can progress through pus formation and sloughing to leave a contracted scar.

Acute Effects:

Inhalation:  Toxic by inhalation.  May cause damage to the respiratory system.

Ingestion:  Toxic by ingestion.  May cause irritation to the gastrointestinal tract.

Skin:  May cause irritation.

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  May cause pneumonitis, liver and kidney abnormalities.

Ingestion:  No chronic health effects recorded.

Skin:  May cause dermatitis and keratitis.

Eye:  May cause conjunctivitis.

Target Organs:  May affect the respiratory system, kidneys, and nervous system.

Medical Conditions Possibly Aggravated by Exposure:  Pre-existing respiratory disorders.

Carcinogenicity:  NTP:  No     IARC:  No        OSHA:  No

 

EMERGENCY AND FIRST AID PROCEDURES:

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

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

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

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

 

 

IV.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  No data 

Incompatibility (Material to Avoid):  Oxidizing agents

Hazardous Decomposition Products:  Toxic metal oxide fume.

Hazardous Polymerization:  Will not occur.

 

 

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled:  Wear appropriate respiratory and protective equipment specified in section VIII.  Isolate spill area, provide ventilation and extinguish sources of ignition.  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.

Waste Disposal Method:  Dispose of in accordance with Local, State and Federal Waste Disposal Regulations.

 


VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  Where airborne exposures may exceed OSHA/ACGIH permissible air concentrations, the minimum respiratory protection recommended is negative pressure air purifying respirator with cartridges that are NIOSH/MSHA approved against dusts, fumes and mists having a TWA less than  0.05 mg/m3

Ventilation:  Local exhaust - melt metal under hood with inert gas cover.  Mechanical - use filters to trap oxide smoke generated.  For cutting or grinding operations, use local exhaust ventilation if necessary, to keep exposure levels below permissible limits.

Protective Gloves:  Rubber for chemical treatment; high temperature for melting.

Eye/Face Protection:  Safety glasses recommended where the possibility of getting dust particles in eyes exists.

Other Clothing and Equipment:  Full protective clothing is recommended for exposures that exceed permissible air concentrations.  All contaminated clothing should be removed before leaving plant premises.

 

 

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Store in a cool, dry place in tightly sealed containers.  Ensure good ventilation at the workplace.  Open and handle container with care.

Other Precautions:  Indium arsenide in solid form can be handled without any special precautions.  Protective gloves should be worn when handling rough or sharp pieces.  Activities which generate dust or fume should be avoided.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area.  Wash thoroughly before eating and 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.
