4.FIRST AID MEASURES
Eye
Flush gently with running water. Seek medical attention if irritation develops
Inhalation If exposure occurs leave exposure area immediately. If irritation persists, seek
medical attention.
Skin
Ingestion
Gently flush affected areas with water.
For advice, contact a poisons information centre or a doctor. Due to product form
and application, ingestion, is considered unlikely.
Advice to doctor
Treat symptomatically.
First Aid facilities
Eye wash facilities should be provided.
5.FIRE FIGHTING MEASURES
Flammability

6.ACCIDENTAL RELEASE MEASURES
Spillage
If spilt (bulk), wear dust-proof goggles, cotton/leather gloves, a class P2(partulate)
respirator (where an inhalation risk exists) and coveralls or protective clothing.
Moisten with water to prevent a dust hazard and place in sealable containers for
disposal.

7. HANDLING AND STORAGE
Handing Use safe work practices to avoid eye or skin contact and inhalation. observe good personal
hygiene. Wash hands before eating.
Storage Store in cool, dry, well ventilated area, removed from acids (eg hydrofluoric acid) and foodstuffs.
Ensure containers are adequately labeled, protected from physical damage and sealed when not
in use. Bulk material should be stored in a manner that minimises dust generation.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Ventilation Do not inhale dusts. use in well ventilated areas-open doors and windows. In poorly ventilated
areas, mechanical extraction ventilation at source is recommended. Maintain dust levels below
the recommended exposure standard.

10. STABILITY AND REACTIVITY
Reactivity
Incompatible with hydrofluoric acid. Contact will produce toxic silicon tetrafluoride
gas. Heating this product above 500C may result in the formation of crystalline silica
(cristobalite / tridymtie), which can cause silicosis and is a known human carcinogen.
Decomposition products
Not expected to evolve hazardous decomposition products.
11. TOXICOLOGICAL INFORMATION
Health Hazard Irritant, use safe work practices to avoid dust generation/inhalation and skin/eye
contact.
Summary
Exposure to amorphous silica does not cause silicosis, however there is a risk of
pulmonary fibrosis associated with the crystalline silica contaminant. Crystalline silica (Quartz) is classified as
a known human carcinogen. Due to the low levels present, adverse health effects are only anticipated following
long term exposure at concentrations exceeding the TWA.
Eye
Irritant exposure may result in, lacrimation, irritation, pain and redness.
Inhalation
Irritant dust generation may result in mucous membrane irritation of the upper
respiratory tract with over exposure chronic exposure to crystalline silica may result
in lung disease (silicosis). Crystalline silica is classified as carcinogenic to humans.
Skin
Irritant. Prolonged contact may result in irritation, itching and possible skin rash.
Ingestion
Irritating to gastrointestinal tract.
