Hydrogen Hexabromoplatinate (IV)
Eye contact : In case of contact, immediately flush eyes with a copious amount of water for at least
15 minutes. Obtain medical attention immediately.
See section 11 for more detailed information on health effects and symptoms.

5. Fire-fighting measures
Extinguishing media : Use an extinguishing agent suitable for surrounding fires.
Special exposure hazards : No specific hazard.
This material is very toxic to aquatic organisms. Fire water contaminated with this
material must be contained and prevented from being discharged to any waterway,
sewer or drain.
Special protective : Fire fighters should wear appropriate protective equipment and self-contained
equipment for fire-fighters breathing apparatus (SCBA) with a full face-piece operated in positive pressure
mode.
Remark : The residue, ash or char left after a fire may have catalytic properties and may
promote the re-ignition of flammable materials and vapours.

6. Accidental release measures
Personal Precautions : Immediately contact emergency personnel. Keep unnecessary personnel away. Use
suitable protective equipment (Section 8).
Environmental precautions : Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains
and sewers.
Methods for cleaning up : If emergency personnel are unavailable vacuum or carefully scoop up spilled
materials and place in an appropriate container for disposal. Avoid creating dusty
conditions and prevent wind dispersal.

7. Handling and storage
Handling : Do not get in eyes, on skin or on clothing. Keep container closed. Use only with
adequate ventilation. Do not breathe dust. Avoid contact of spilled material and
runoff with soil and surface waterways. Wash thoroughly after handling.
Storage : Keep container tightly closed. Keep container in a cool, well-ventilated area.
Packaging materials
Recommended : Use original container.

8. Exposure controls/personal protection
Ingredient name Occupational exposure limits
platinate(2-), hexabromo-, dihydrogen, (oc- EH40-OES (United Kingdom (UK)). Sensitiser skin, Sensitiser
6-11)- inhalation Notes: Halogeno-Platinum Compounds
TWA: 0.002 mg/m3 8 hour(s). Form: As Pt
Exposure controls
Occupational exposure : Use process enclosures, local exhaust ventilation, or other engineering controls to
controls keep airborne levels below recommended exposure limits. If user operations
generate dust, fume or mist, use ventilation to keep exposure to airborne
contaminants below the exposure limit.
Respiratory protection : Use a properly fitted, particulate filter respirator complying with an approved standard
if a risk assessment indicates this is necessary.Respirator selection must be based on
known or anticipated exposure levels, the hazards of the product and the safe working
limits of the selected respirator.
Hand protection : Chemical-resistant, impervious gloves or gauntlets complying with an approved
standard should be worn at all times when handling chemical products if a risk
assessment indicates this is necessary.
Eye protection : Safety eyewear complying with an approved standard should be used when a risk
assessment indicates this is necessary to avoid exposure to liquid splashes, mists or
dusts.
Skin protection : Personal protective equipment for the body should be selected based on the task
being performed and the risks involved and should be approved by a specialist before
handling this product.
