Section 3: Composition/Information on Ingredients Blended Cement consists of a crystalline mass manufactured from substances mined from the earth’s crust. It contains trace amounts of naturally occurring but potentially hazardous chemical entities including metals such as chromium and nickel and crystalline silica. It also contains added supplementary cementitious material fly ash or ground granulated slag. All significant constituents are listed below: Chemical Entity Proportion CAS Number Portland Cement Clinker 20-95 65997-15-1 Gypsum CaSO 2H O 0-5 10101-41-4 Calcium Oxide 0-3 1305-78-8 Fly ash where applicable 8-50 69131-74-8 Ground Granulated Blast Furnace slag where applicable 8-80 65999-69-2 Limestone CaCO 0-5 1317-65-3 Hexavalent Chromium Cr VI 20 ppm 1333-82-0 Crystalline Silica Quartz 1-10 14808-60-7 Section 4: First Aid Measures Swallowed: Rinse mouth and lips with water. Do not induce vomiting. Give water to drink to dilute stomach contents. If symptoms persist seek medical attention. Eyes: Flush thoroughly with flowing water for 15 minutes to remove all traces. If symptoms such as irritation or redness persist seek medical attention. If wet cement is splashed in the eye always treat as above and seek urgent medical attention. Skin: Remove heavily contaminated clothing immediately. Wash off skin thoroughly with water. Use a mild soap if available. Shower if necessary. Seek medical attention for persistent irritation or burning of the skin. Inhaled: Remove to fresh air away from dusty area. If symptoms persist seek medical attention. First Aid Facilities: Eye wash station. Washing facilities with running water. Advice to Doctor: Treat symptomatically. Wet cement burns to skin or eye may result in corrosive caustic burns. Ingestion of significant amounts of cement dry or wet is unlikely. Do not induce emesis or perform gastric lavage. Neutralization with acidic agents is not advised because of increased risks of exothermic burns. Water-mineral oil soaks may aid in removing hardened cement from the skin. Ophthalmological opinion should be sought for ocular burns.

SDS No. CA002 | Page 3 of 6 Section 5: Fire Fighting Measures Fire/Explosion Hazard: Blended Cements are stable substances compatible with most other building materials will not decompose into hazardous by-products and do not polymerise Hazchem Code: None allocated Flammability: Not flammable Extinguishing Media: None required Hazards from Combustion Products: None Special Protective Precautions and equipment for fire fighters: None required Section 6: Accidental Release Measures Spills: Spills are best cleaned up by vacuum device to avoid generating airborne dust. Recommendations on Exposure Control and Personal Protection should be followed during spill clean-up. Keep product out of storm water and sewer drains. Wetting during clean-up will cause formation of setting cement. Section 7: Handling and Storage Handling: When supplied in bags these need to be handled in accordance with manual handling Code of Practice. Storage: Protect from moisture to prevent hardening. Storage of cement may be in concrete silos steel bins or plastic lined multi-ply paper bags. Section 8: Exposure Controls/Personal Protection Exposure Limits: National Occupational Health Safety Commission NOHSC Australia Occupational Exposure Standard: Exposure to dust should be kept as low as practicable and below the following OES. Portland Cement: 10mg/m³ TWA time-weighted average as inspirable dust. Crystalline silica quartz: 0.1 mg/m³ TWA as respirable dust ≤7 microns particle equivalent aerodynamic diameter. Chromium VI hexavalent: 0.05 mg/m³ sensitiser Engineering Controls: All work with dry cement should be carried out in such a way as to minimise dust generation exposure to dust and repeated or extended skin contact. When handling dry cement use local mechanical ventilation or extraction in areas where dust could escape into the work environment. For bulk deliveries closed pumping systems are recommended. For handling of individual bags follow instructions below if no local exhaust ventilation is available. Local dust extraction and collection may be used if necessary to control airborne dust levels. Work methods and engineering should aim to minimise contact with wet cement onto exposed skin. Work areas should be cleaned regularly. Personal Protection Skin: Minimise contact with Portland Cement materials. When handling dry or wet cement wet concrete mortar or grout personnel should wear protective clothing and impervious footwear and gloves such as PVC see Australian and New Zealand Standards AS/NZS 4501 and AS 2161. Never kneel in wet cement or allow extended contact of skin with wet cement. Remove clothing which has become contaminated with wet or dry cement to avoid prolonged contact with the skin. If cement gets into boots remove socks and boots immediately and wash skin thoroughly. Wash work clothes regularly. To avoid contamination of face and lips and ingestion wash hands before eating or smoking. Eyes: Splash resistant Safety Glasses with side shields or safety goggles AS/NZ 1336 or a face shield should be worn to ensure all contact with eyes is avoided.

SDS No. CA002 | Page 4 of 6 Section 8: Exposure Controls/Personal Protection Co n t’ d Personal Protection Respiratory: Where engineering and handling controls are not adequate to minimise exposure to total dust and to respirable crystalline silica wear a suitable P1 or P2 particulate respirator AS/NZS 1715 and AS/NZS 1716. Use only respirators that bear the Australian Standards mark and are fitted and maintained correctly. For dust levels approaching or exceeding the NES see above a more effective particulate respirator as described in AS/NZS 1715 should be worn. Procedures for effective use of respirators should be applied and supervised. Section 9: Physical and Chemical Properties Appearance: A fine powder ranging in colour from grey to off-white Odour: No distinctive odour Boiling/Melting Point: Melting point 1200ºC Vapour Pressure: Not applicable Specific Gravity: 2.7 – 3.2 Flash Point: Non applicable Flammability Limits: Not applicable Solubility In Water: Slight reacts on mixing with water forming an alkaline caustic solution pH 11 Particle Size: Up to 40 of the fresh dry material may be respirable below 10 microns Section 10: Stability and Reactivity Blended Cements are stable substances compatible with most other building materials will not decompose into hazardous by-products and do not polymerise. Chemical Stability: Chemically stable Conditions to Avoid: Keep free of moisture during storage Incompatible Materials: None Hazardous Decomposition Products: None Hazardous Reactions: None Section 11: Toxicological Information There is no direct toxicological data on Portland Cements. Health effects information is based on reported effects in use from overseas and Australian reports. Short Term Acute Exposure Swallowed: Unlikely under normal industrial use. Mildly abrasive and corrosive to mouth and throat if swallowed. May cause nausea stomach cramps and constipation. Eyes: Irritating and corrosive to the eyes and may cause alkaline burns. Cement dust is irritating to the eyes. Exposure to dust may aggravate existing eye irritations. Skin: Dust is irritating and drying to the skin. Direct contact with wet cement may cause serious skin burns. Within 12 to 48 hours after one- to six-hour exposures possible first second or third degree burns may occur. There may be no obvious pain at the time of the exposure. Chronic skin disorders may be aggravated by exposure to dust or contact with wet cement. Inhaled: Cement dust is irritating to the nose throat and respiratory tract causing coughing and sneezing. Pre-existing upper respiratory and lung diseases including asthma and bronchitis may be aggravated.

SDS No. CA002 | Page 5 of 6 Section 11: Toxicological Information Con t’ d Long Term Chronic Exposure Eyes: Dust may cause irritation and inflammation of the cornea. Skin: Repeated contact causes irritation and drying of the skin and can result in skin reddening and skin rash dermatitis. Over time this may become chronic and can also become infected. Persons who are allergic to chromium may develop an allergic dermatitis which aggravates the irritant effects and this combination can lead to chronic cement dermatitis and serious disability particularly affecting the hands. Inhaled: Repeated exposure to the dust may result in increased nasal and respiratory secretions and coughing. Inflammation of lining tissue of the respiratory system may follow repeated exposure to high levels of dust with increased risk of bronchitis and pneumonia. Repeated and prolonged exposure to dust levels which exceed the OES for crystalline silica see above may occur. This can cause bronchitis and silicosis scarring of the lung. Long term overexposure to respirable crystalline silica dust may increase the risk of other irreversible and serious disorders including scleroderma a disease affecting the connective tissue of the skin joints blood vessels and internal organs. Cement Portland Cement is not classified as a carcinogen by NOHSC. Of the ingredients Hexavalent Chromium Cr VI is classified as a carcinogen by NOHSC. There is debate in the medical literature concerning whether there is any risk of lung cancer arising from long term high overexposure to respirable crystalline silica. Risk of lung cancer has not been identified from using Portland Cements containing silica. The International Agency for Research on Cancer IARC has classified crystalline silica inhaled in the form of quartz or cristobalite from occupational sources as carcinogenic to humans Group 1. NOHSC has not classified crystalline silica as a carcinogen. Section 12: Ecological Information Ecotoxicity: Product forms an alkaline slurry when mixed with water. Persistence and Degradability: Product is persistent and would have a low degradability. Mobility: A low mobility would be expected in a landfill situation. Section 13: Disposal Considerations Blended Cement can be treated as a common waste for disposal or dumped into a landfill site in accordance with local authority guidelines. Keep material out of storm water and sewer drains. Measures should be taken to prevent dust generation during disposal and exposure and personal precautions should be observed see above Section 14: Transport Information Transportation is done in bulk or bag form by Ship Rail and Road.
