3. HAZARD IDENTIFICATION
Chloroiridic acid has been shown to be corrosive to the skin, but non-irritating
to the eyes of rabbits.
In general, iridium compounds are regarded as being less toxic than those of
platinum, palladium or osmium.
Prolonged or repeated contact with the skin may lead to dermatitis. Toxic
fumes will be evolved on heating. Users should note that a case of a type 1
sensitization has been reported following exposure to this material.

4. FIRST AID MEASURES
Over-exposure may produce the following symptoms -
First Aid
Inhalation - irritation of the respiratory tract, producing coughing.
Ingestion - abdominal pain.
Eye contact - redness, irritation, blurred vision and pain.
Skin - redness and irritation. 聽 聽 聽

remove from exposure and allow to rest in fresh air. Seek medical attention. 聽
First Aid - Inhalation
rinse mouth with clean water and give water or milk to drink. Seek medical
First Aid - Ingestion
attention.
irrigate with water or isotonic saline solution for 15 minutes. Seek medical
First Aid - Eyes
attention.
remove contaminated clothing and wash skin with soap and water. If
First Aid - Skin
symptoms persist, seek medical attention. 聽


5. FIRE FIGHTING MEASURES
Although the material is not flammable, toxic fumes will be produced if
involved in a fire. The residue, ash or char left after a fire may have catalytic
properties and may promote the re-ignition of flammable materials and
vapours. Wear self-contained breathing apparatus and personal protective
equipment. Use any extinguisher suitable for the surrounding fire. 聽 聽
