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.

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.
