V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

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

Exposure to iridium compounds may cause irritation to the eyes or respiratory tract.  Toxicity of iridium is not known.  It is predicted to have toxicity similar to osmium and platinum, two members of the same group.  The chloride ion generally has a very low toxicity.

Acute Effects:

Inhalation:  Irritant

Ingestion:  No data

Skin:  Irritant

Eye:  Irritant

Chronic Effects:  No data

Sensitization:  No sensitizing effects known.

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

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove patient from area of exposure to fresh air.  If required, provide artificial respiration. Keep patient warm.  Contact a physician immediately.

INGESTION:  Contact poison control center/physician immediately.

SKIN:  Immediately wash with soap and water for 15 minutes and rinse thoroughly.  Seek immediate medical advice.

EYE:  Flush with eye bath, including under eyelids, for at least 15 minutes.  Consult a doctor.

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  Extreme heat

Incompatible Materials:  Oxidizers, acids, alkalis, organic solvents, metal powder.

Hazardous Decomposition Products:  Chlorine, iridium, hydrochloric acid.

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.  Sweep up and place in airtight plastic container.  Ship to precious metal refiner.

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

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  In dusting conditions, use a NIOSH approved respirator.

Ventilation:  Handle in a dry, controlled atmosphere.  Handle in an inert gas such as argon.  Use local exhaust as needed to maintain airborne exposure below control limits.  General 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:  Store in cool, dry place,  keep tightly sealed when not in use, read MSDS before using.

Other Precautions:  Iridium chloride may react with water.  Handle and store in a controlled environment and in an inert gas such as argon.

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.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
