V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of platinum-iridium have not been thoroughly investigated and recorded.

Platinum is considered to have low toxicity.  Exposure to dust of pure metallic form may cause skin sensitization and irritation to the eyes.  Ingestion and inhalation may have irritating effects.

Pure iridium is clinically inert.  There are not reports of acute or chronic health effects to workers handling iridium and its compounds.  (Sax, Dangerous Properties of Industrial Materials)

Acute Effects:

Inhalation:  Inhalation of dust may cause irritation of the respiratory tract with coughing, wheezing and difficulty breathing, sensitization and cyanosis.

Ingestion:  No acute effects recorded.

Skin:  May cause irritation and allergic reaction.

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  May cause pulmonary fibrosis.

Ingestion:  No chronic effects recorded.

Skin:  May cause dermatitis and sensitization.

Eye:  No chronic effects recorded.

Medical Conditions Generally Aggravated by Exposure:  None known

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 if symptoms persist.

INGESTION:  Give 1-2 glasses of milk or water and induce vomiting, seek medical attention if symptoms persist.  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 irritation persists.

EYE:  Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek medical attention if irritation persists.

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  None expected

Incompatibility (Material to Avoid):  Oxidizing agents

VII.   SPILL OR LEAK PROCEDURES

Steps to be Taken in Case Material is Released or Spilled:  Wear appropriate respiratory protection and protective clothing specified in section VIII.  Scoop up or vacuum using a high efficiency particulate absolute HEPA filter and place the spilled material into a container for reclamation or disposal.  Take care not to raise dust.

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

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH approved dust respirator is recommended if dust is generated.

Ventilation:  Local exhaust ventilation as necessary to control any air contaminants to within their PEL’s or TLV’s during the use of this material.

Protective Gloves:  Chemical resistant gloves should be worn.

Eye Protection:  Safety glasses (with side shields)

Other Protective Clothing or Equipment:  Body protection as necessary to prevent skin contact.

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Store in a cool, dry location.  Keep container tightly closed.  Wash thoroughly after handling.  Avoid generating or breathing dust.

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.
