Potential Health Effects
Acute
Swallowed
Non-toxic. There are no known hazards resulting from accidental ingestion of
zircon sand as may occur during normal handling. Swallowing a large amount
may result in irritation to the digestive system due to abrasiveness.
Eye
the
zircon grains and dust can be moderately irritating due to abrasiveness.
Skin
Low Hazard
Inhaled
the normal grain size of the product precludes from being an inhalation
hazard, however handing of bulk materials may generate some dust. This is
normally regarded as general
nuisance dust, but can be irritating if inhaled
at high concentration. May cause symptoms such as coughing or sneezing.
Chronic
Silica
crystalline silica is a known cause of lung fibrosis (silicosis). It has been
classified as a human carcinogen. (IARC). Zircon sand contains a small
amount of free quartz, (up to 0.5%) and precautions should be taken to
avoid inhaling the dust.
Radiation
zircon contains naturally occurring radioactive elements of
the uranium
and thorium series. The zircon sands produced by ILUKA Resources contain
low concentrations of these impurities, with typical specific activities of 0.6 to
1.2 Bq/gm (thorium 223) and to 1.5 to 4.5 Bq/gm (uranium -238). Daughter
products are present typically at equilibrium concentrations. The main
radiological hazard is internal exposure to alpha particles from inhaled dust.
Suitable dust control shall be employed to ensure occupational exposure to
generated dust and alpha particles are kept as low as reasonable achievable.
As a guide, continuous worker exposure to respirable dust levels above
1.5mg/,3 could give rise to annual internal exposures above 1mSv. External
exposure is from gamma radiation. Continuous exposure (2000 hours per year)
annual external dose above 1 mSV
.

FIRST AID MEASURES
Swallowed
First aid is unlikely to be required, but if necessary wash mouth out with water
ensuring the mouthwash is not swallowed. Seek medical attention as a
precaution if discomfort occurs.
Eye
Hold eyelid open and flush with plenty of clean water
. Continue for at least 15
minutes or until grit is removed. Seek medical attention if soreness or irritation
persists.
Skin
Gently remove contaiminated clothing to avoid generatiing dust. wash material
from the skin. If repeated contact result in skin irritation, seek medical advice.
Launder clothing before re-use.
Inhaled
Move to fresh air
. Blow nos to remove particulates from nasal passages. If
anyadverse reaction develops, seek medical attention.

6.
ACCIDENTAL RELEASE MEASURES
Spills and
Disposal
Wear safety equipment as for normal handling. Avoid generating dust.
Vacuum up if possible. Otherwise sweep up and re-cycle. If the spilled
Product is not suitable for re-use, damp down, collect and where possible
Return to manufacture for reprocessing. Any disposal to an approved landfill
Site and cover with clean fill shall be conducted in accordance with state/local
Council regulations.
