Administrative data
First-aid measures
Emergency measure - Inhalation: Remove patient to fresh air. Seek medical attention.
Emergency measure - Eyes: Wash the eyes with clean water or isotonic saline for at
least 10 minutes. If irritation occurs seek medical
attention.
Emergency measure - Skin: Remove contaminated clothing, wash skin thoroughly with soap
and water. If irritation occurs seek medical attention.
Emergency measure - Ingestion: Seek immediate medical attention.
Fire-fighting measures
Recommended extinguishing agent: Water, carbon dioxide, foam and dry powder may be used.
Product arising from burning: Products of combustion may contain oxides of carbon and
iridium.
Product determined by test: N
Protective equipment: Full protective clothing and self-contained breathing
apparatus must be worn.
Accidental release measures
Emergency measures in case of spillage: Wear suitable protective clothing (see 2.3.1).
Avoid dust formation. Absorb spillages of solutions with a
suitable inert material (eg sand or soil). Carefully
transfer the spillage to labelled waste containers, or use a
sealed industrial vacuum machine. Dispose of waste material
by recovering the metal at a precious metal refinery in
accordance with local regulations. Wash the spill area with
water and detergent. Do not allow washings to enter
watercourses.
Handling and storage
Handling: Ensure adequate ventilation. Avoid inhalation and contact
with skin and eyes. Protective clothing, chemical resistant
gloves and goggles should be worn together with an
appropriate filter-type respirator conforming to the
appropriate national standards.
Storage: Store in tightly closed containers in a cool dry
well-ventilated area.
Packaging of the substance and or preparation: Substance: Store in plastic containers.
Preparation: Acetic acid solution stored in UN 1H1
specification plastic drums.

Stability and reactivity
Danger other than fire: The substance decomposes at temperatures in excess of 256
deg C, if involved in a fire. The residue, ash or char left
after a fire may have catalytic properties and could promote
re-ignition of flammable materials or vapours.

Disposal considerations
Industry - Possibility of recovery/recycling: All residues and spilt material should be recovered and
returned to a precious metal refinery for iridium recovery.
(A623)
Industry - Possibility of neutralisation: None known.
Industry - Possibility of destruction: controlled discharge: Not recommended.
Industry - Possibility of destruction - incineration: Not recommended.
Industry - Possibility of destruction - water purification: Not recommended. The substance should not be discharged
directly to the sewage system or the aqueous environment.
Industry - Possibility of destruction - other: The substance, preparations of the substance, contaminated
containers or spillages of solutions mixed with inert
material (eg sand or soil) should be disposed of by recovery
of the metal at a precious metal refinery.
Public at large - Possibility of recovery/recycling: The substance will not enter the public domain.
