V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

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

Oxidation of osmium compounds may form the volatile and highly irritating osmium (VIII) oxide.  Exposure may cause bronchitis and dermatitis, occular disturbances.  Ingestion may cause heavy metal poisoning.  Irritating to skin and mucous membranes.

CarcinogenicityNTP:  No      IARC:  No      OSHA:  No

 

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Supply fresh air.  If required, provide artificial respiration.  Keep patient warm.  Seek immediate medical advice.

INGESTION:  Seek immediate medical advice.

SKIN:  Immediately wash with soap and water and rinse thoroughly.  Seek immediate medical advice.

EYES:  Flush eyes with lukewarm water, lifting upper and lower eyelid, for at least 15 minutes.  Seek medical advice.

 

 

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  Extreme heat, water/moisture.

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.  Sweep up and place in airtight plastic container.  Take care not to raise dust.

Waste Disposal Method:  Ship to precious metal refiner.

 

 

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH/MSHA approved respirator when high concentrations are present.

Ventilation:  Use local exhaust to maintain concentration at low exposure levels.  Hygroscopic, handle under dry, inert gas.

Protective Gloves:  Rubber for all contact

Eye Protection:  Goggles

Other Protective EquipmentNormal labwear.

 

 

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Keep container tightly sealed.  Store in cool, dry place in tightly closed containers.  Ensure good ventilation at the workplace.  Store away from oxidizing agents.  Store away from water/moisture.

Other Precautions:  This product is hygroscopic.  Store under dry inert gas.  Protect from humidity and water.

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.
