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
