4. 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. Give one or two glasses of water to drink. Seek medical attention if a large quantity has been swallowed.

Inhaled: Blow nose to remove particulates from nose. Move to area with fresh air. Seek medical attention if adverse reaction develops.

Skin: Remove contaminated clothing gently to avoid creating dust. Wash skin. If skin becomes irritated, seek medical attention. Launder affected clothing before re-use

Eye: Hold eyelid open and flush with clean water. Continue until grit is removed. Seek medical attention if irritation or soreness persists.

Acute Swallowed: Non-toxic. No known detrimental effect from accident ingestion as may occur during normal handling. Ingestion of large amounts may cause irritation to the gastro-intestinal system due to abrasiveness.

SAFETY DATA SHEET Monazite

Inhaled: Mainly regarded as nuisance dust but may be irritating if inhaled at high concentrations. May cause coughing and/or sneezing.

Skin: Low hazard.

Eye: Solid and dust can be moderately irritating due to abrasiveness.

Chronic Radiation: Monazite contains naturally occurring radioactive elements of the uranium and thorium series. The Monazite produced by RZ Resources Ltd contains concentrations of these impurities with a typical specific activity of approximately 200 Bq/g of combined uranium and thorium.

• 170 Bq/g (thorium-232) and • 30 Bq/g (uranium-238).

Daughter products are present, usually at equilibrium concentrations but the main radiological hazard is internal dust. As a guide, continuous worker exposure to respirable dust levels above 3.5mg/m3 could give rise to annual internal exposures above 1 mSv.

External exposure is from gamma radiation. Continuous exposure (2000 hours per year) within 2 meters of bulk Monazite could give rise to an annual external dose above 1 mSv.

Silica: Monazite contains amounts of free quartz and precautions should be taken to avoid inhaling the dust.

First Aid Facilities: Eye Wash Station

Doctor Treatment: Treat symptomatically

5. FIRE FIGHTING MEASURES

Non-flammable, non-combustible. Use suitable firefighting measures for the surrounding fire.

6. ACCIDENTAL RELEASE MEASURES

Emergency Procedures: Not relevant

Containment and Clean-up: Wear safety equipment for normal handling. Avoid generating dust. Vacuum up, if possible, otherwise sweep up and recycle. If the spilled product is not suitable for re-use, dispose of as radioactive waste.

7. HANDLING AND STORAGE

Handling: Dust generation should be minimised when handling. Wash thoroughly after handling.

Storage: Storage areas should be ventilated.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

National Exposure Standards (Source: Safe Work Australia):

Ingredient TWA (mg/m3) STEL (mg/m3) Titanium dioxide 10 -

Iron Oxide 5 -

Respirable silica (quartz) 0.05 -
