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 Gently flush affected areas with water.

Ingestion 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 Not flammable. No fire or explosion hazard exists. Not expected to evolve hazardous decomposition products.

Fire and Explosion Non flammable .No fire or explosion hazard exists.

Extinguishing Non flammable

Hazchem Code None Allocated

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 STORAGEHanding 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 PROTECTIONVentilation 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 REACTIVITYReactivity 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 productsNot expected to evolve hazardous decomposition products.

11. TOXICOLOGICAL INFORMATIONHealth 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.


12. ECOLOGICAL INFORMATIONEnvironmentThe main component/s of this product occur naturally in the earth’s crust. it is not anticipated to cause any adverse effects to plants or animals.
