Product and Company identification Trade / Commercial Name: Syfer-45K Chemical Name: Calcium Carbonate Formula: CaCO 3 Synonyms: Aggregate, Aglime, Barn lime, Coverstone, Fluing agent, Manufactured sand. CAS No: Company Name: Address: Emergency Tel: (014) Tel: (012) Fax: (012) Composition 12 Victoria link Route 21 Corporate Irene Ext.31 Calcium Carbonate > 90% Magnesium Carbonate MgCO 3 < 4% Iron Oxide Fe 2 O < 0.5% Aluminium Oxide Al 2 O < 0.5% Silicon Dioxide SiO < 3% 3. Hazards Identification Routes of entry: Inhalation Ingestion Skin contact Eye contact Health hazards: Inhalation: Nuisance dust: May cause irritation to the nasal passages, respiratory tract. Inhalation can cause a flu-like illness characterized by coughing and shortness of breath.

2 MATERIAL SAFETY DATA SHEET Page 2 of 6 Ingestion: Ingestion in very large quantities may cause rapid bowel evacuation. Skin Contact: No adverse effects expected. Eye Contact: May cause irritation. Chronic Exposure: No information found. Aggravation of Pre-existing Conditions: No information found. 4. First Aid Measures Inhalation: Remove to fresh air. Get medical attention for any breathing difficulty. Ingestion: Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice. Skin Contact: Wash exposed area with soap and water. Get medical advice if irritation develops. Eye Contact: Wash thoroughly with running water. Get medical advice if irritation develops 5. Fire Fighting Measures Flammability of the Product: Non-flammable. Risks of explosion of the Product: Not considered to be an explosion hazard. Fire Fighting Media and Instructions: Use any means suitable for extinguishing surrounding fire Special Remarks on Explosion Hazards: In the event of a fire, wear full protective clothing. 6. Accidental Release Measures Small Spill:

3 MATERIAL SAFETY DATA SHEET Page 3 of 6 Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements. Large Spill: Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow evacuating through the sanitary system. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities 7. Handling And Storage Keep in a tightly closed container, stored in a cool, dry, ventilated area. Isolate from incompatible substances. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product. 8. Exposure Controls/Personal Protection Occupational Exposure Limits: TWA: 10 (mg/m3) from ACGIH (TLV) Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Personal Respirators (NIOSH Approved): If the exposure limit is exceeded, a full face piece respirator with dust/mist filter may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres. Skin Protection: Wear protective gloves and clean body-covering clothing. Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area. 9. Physical & Chemical Properties

Stability And Reactivity Stability: Stable under ordinary conditions of use and storage. Hazardous Decomposition Products: Contact with powerful oxidizing agents such as fluorine, boron trifluoride, chlorine trifluoride, manganese trifluoride, andoxygen difluoride may cause fire and/or explosions. Silica dissolves in hydrofluoric acid producing a corrosive gas- silicon tetrafluoride. Hazardous Polymerization: Will not occur. Incompatibilities: Contact with powerful oxidizing agents such as fluorine, boron trifluoride, chlorine trifluoride, manganese trifluoride, andoxygen difluoride may cause fire and/or explosions. Silica dissolves in hydrofluoric acid producing a corrosive gas- silicon tetrafluoride. Conditions to Avoid: Contact with powerful oxidizing agents such as fluorine, boron trifluoride, chlorine trifluoride, manganese trifluoride, andoxygen difluoride may cause fire and/or explosions. Silica dissolves in hydrofluoric acid producing a corrosive gas- silicon tetrafluoride. 11. Toxicological Information No information found relating to normal routes of occupational exposure. 12. Ecological Information Eco-toxicity: No information found. 13. Disposal Considerations Disposal Method Product: There are no uniform EC regulations for the disposal of chemicals or residues. Chemical residues generally count as special waste. The disposal of the latter is regulated in the EC member

5 MATERIAL SAFETY DATA SHEET Page 5 of 6 countries through corresponding laws and regulations. We recommend that you contact the authorities in charge or approved waste disposal companies which will advise you on how to dispose of special waste 14. Transport Information Hazchem Code: 1z ( 1 - indicates the use of solid streams of water, z - Contain' attempts to achieve this by confining the material within finite bounds and minimising environmental impact. It also allows recovery of the material where such a procedure is safe and practicable.) ERG No: 171 EAC: 12 SIC: 2819 IMDG-Shipping Name: Not Regulated. 15. Regulatory Information EEC Hazard Classification DOT Classification: Not a DOT controlled material (United States). Identification: Not applicable. Special Provisions for Transport: Not applicable National Legislation: Not regulated 16. Other Information NFPA Ratings: Health: 1 Flammability: 0 Reactivity: 0 Label Hazard Warning: CAUTION! MAY CAUSE IRRITATION TO EYES AND RESPIRATORY TRACT. Label Precautions: Avoid contact with eyes, skin and clothing. Avoid breathing dust. Use with adequate ventilation. Wash thoroughly after handling. Keep container closed.

6 MATERIAL SAFETY DATA SHEET Page 6 of 6 Label First Aid: If inhaled, remove to fresh air. Get medical attention for any breathing difficulty. In case of contact, immediately flush eyes or skin with plenty of water for at least 15 minutes. Get medical attention if irritation develops or persists. Product Use: Laboratory Reagent.
