V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

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

The main symptoms of thallium poisoning are peripheral neuropathy and loss of hair.  Acute poisoning causes paresthesia, ataxia, alopecia, fever, coryza, abdominal pain, nausea and vomiting.  Symptoms may progress to lethargy, speech disorders, tremors, convulsions, cyanosis, pulmonary edema, bronchopneumonia and death.  Kidney, liver and brain damage can occur.  Thallium poisoning during the first trimester of pregnancy can cause skeletal deformities, alopecia, low birth weight and premature birth.  Chronic thallium poisoning may produce alopecia, salivation and a blue line on the gums.  Damage to the gastrointestinal, endocrine system and kidneys may also occur.

Acute Effects:

Inhalation:  Inhalation of thallium will cause irritation of mucous membranes and the respiratory tract.  Can cause pulmonary edema.

Ingestion:  Ingestion of thallium compounds can cause fatigue, limb and joint pain, discoloration of and loss of hair, peripheral neuritis, diarrhea, vomiting, severe pain in the calves of legs, albuminuria, eosinophilia, lymphocytosis and optic neuritis followed by atrophy.

Skin: Strong skin irritant.  Skin contact may cause dermatitis on first contact.  Thallium compounds can be absorbed through the skin to cause effects described above.

Eye:  Strong eye irritant.

Medical Conditions Generally Aggravated by Exposure:  Lung disorders, liver and kidney damage.

CarcinogenicityNTP:  No        IARC:  No     OSHA:  No

 

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove victim to fresh air, keep warm and quiet, administer oxygen if required, get immediate medical attention.

INGESTION:  Do not induce vomiting.  Seek immediate, competent medical attention.

SKIN:  Brush off material, wash affected area thoroughly with soap and water, and wash contaminated clothing before reuse.

EYES:  Flush with copious amounts of water, including under eyelids, for at least 15 minutes.  Seek medical attention.

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled:  Isolate area, wear appropriate protective equipment.  Carefully scoop up material, vacuum powder using HEPA filter, avoid raising dust.  Thoroughly clean spill area.

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

 

 

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type):  NIOSH approved full face respirator with high efficiency filters.

Ventilation:  Use local exhaust to maintain concentration at low exposure levels.  General exhaust is not recommended.

Protective Gloves:  Impervious gloves

Eye Protection:  Safety goggles

Other Protective Equipment:  Protective clothing to prevent skin contact or clothing contamination.

 

 

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and StorageWash thoroughly after handling, keep container closed, thallium compounds are extremely poisonous, avoid all contact.

Other Precautions:  Very toxic by inhalation and if swallowed.  Danger of cumulative effects.

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.
