Unusual Fire and Explosion Hazards:  When heated to decomposition, gold telluride may emit toxic metal oxide fumes.

V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

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

Gold compounds may cause irritation to the eyes and respiratory tract.  Aplastic anemia may result from damage to the blood forming organs.  Gold has caused tumors and reproductive effects in laboratory animals via implant, intraperitoneal and subcutaneous routes.

Elemental tellurium has relatively low toxicity.  It is converted in the body to dimethyl telluride which imparts a garlic-like odor to the breath and sweat.  Heavy exposures may, in addition, result in headache, drowsiness, metallic taste, loss of appetite, nausea, tremors, convulsions, and respiratory arrest (Sax, Dangerous Properties of Industrial Materials).

Acute Effects:

Inhalation:  May cause irritation to the respiratory  system, a dry mouth, metallic taste, gingivitis, garlic odor to breath, sweat and urine.

Ingestion:  May cause a dry mouth, suppression of sweat, malaise, albuminuria, diarrhea, skin reactions, stomatitis, diarrhea, headache, fever, rheumatic pain, black line on gums,  garlic odor to breath and urine.

Skin:  May cause irritation and itching.

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  May cause anorexia, nausea, depression, somnolence and affect the function of the liver and kidneys.

Ingestion:  May cause anorexia, anemia, black line on gums,  ulcerative stomatitis, nausea, depression and somnolence.  May affect the function of the liver and kidneys.

Skin:  May cause dermatitis.

Eye:  No chronic health effects recorded.

Routes of Entry:  Inhalation, Skin, Eyes, Ingestion

Target Organs:  May affect the skin, liver, kidneys and central nervous system.

Medical Conditions Generally Aggravated by Exposure:  Pre-existing skin and 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 medical attention.

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 contaminated clothing, brush material off skin, wash affected area with mild soap and water for 15 minutes, 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

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 and provide ventilation.  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 in accordance with Local, State and Federal regulations.

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  Wear a NIOSH-approved dust, mist, vapor cartridge respirator. 

Ventilation:  Use local exhaust to maintain concentration at or below PEL, TLV. 

Protective Gloves:  Neoprene

Eye Protection:  Safety Glasses

Other Protective Equipment: Wear protective clothing to prevent contamination.

IX.   SPECIAL PRECAUTIONS

Precautions to be Taken in Handling and Storing:  Store in a cool, dry area, Wash thoroughly after handling.  Store in tightly sealed container.  Do not store together with acids.

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.
