2 HAZARD IDENTIFICATION HSNO This product has been approved under the Hazardous Substances and New Organisms Act (HSNO, Approval HSR002544), and is classified as follows: 6.3A H315 - Causes skin irritation. 8.3A H318 - Causes serious eye damage. 9.1D H402 - Harmful to aquatic life. Note: concrete is considered irritating to the skin under the classification system; however, there is a possibility of burns if wet concrete is left in contact with the skin for a prolonged time. Dangerous goods U.N Number Not a Dangerous Good. COMPOSITION This SDS provides information on wet concrete.

Advice to doctor Treat symptomatically.

3 FIRE FIGHTING MEASURES Type of hazard Fire hazard properties Extinguishing media Recommended protective clothing Not applicable. Substance is not flammable. Product will react exothermically with water. Contaminated water will be strongly alkaline. Use firefighting media suitable for surrounding fire. Not applicable. STORAGE AND HANDLING Handling Storage Keep exposure to a minimum, and minimise the quantities kept in work areas. Minimise dust generation and accumulation. Avoid skin and eye contact and inhalation of dust. No special storage requirements, concrete is a live product and will be diverted to a waste stream in the event of non-delivery. Packaging Not applicable products are not supplied in packaged form. ACCIDENTAL RELEASE MEASURES Spill clean-up Emergency procedures If greater than 1000kg is stored, secondary containment is required. Emergency plans to manage any potential spills must be in place. Prevent spillage from spreading or entering soil, waterways or drains. In the event of large spillage (>100kg) of the dry or wetted mixture alert the fire brigade to location and give brief description of hazard. Wear protective equipment to prevent skin, eye and respiratory exposure. Clear area of any unprotected personnel. Contain spill. Prevent by whatever means possible any spillage from entering drains, sewers, or water courses. Clean-up method Collect product avoiding any dust formation, and seal in properly labelled containers or drums for disposal. If contamination of crops, sewers or waterways has occurred advise local emergency services. Disposal Precautions Mop up and collect recoverable material into labelled containers for recycling or salvage. Recycle containers wherever possible. This material may be suitable for approved landfill. Dispose of only in accord with all regulations. The dust may form irritating atmosphere. Contaminated water will be strongly alkaline. Do not allow contaminated water to enter the environment. Wear protective equipment to prevent skin and eye contamination and the inhalation of dust. Work up wind or increase ventilation. EXPOSURE CONTROLS / PERSONAL PROTECTIVE EQUIPMENT Workplace Exposure Standards A workplace exposure standard (WES) has not been established by the Worksafe NZ for this product. There is a general limit of 10mg/m3 for dusts and mists when limits have not otherwise been established. NZ Workplace Exposure Stds (2016) Ingredient WES-TWA* WES-STEL* Cement 10mg/m3 (as nuisance dust) Limestone 10mg/m3 (as nuisance dust) Calcium sulphate hemihydrate 10mg/m3 (as nuisance dust) Aggregates See crystalline silica Crystalline Silica 0.1mg/m3 (respirable dust) Chromium oxide 0.05mg/m3 Flyash See crystalline silica Chemical additives 0.2mg/m3 (as respirable dust)

4 Personal Protective Equipment Eyes Skin Protect eyes with goggles, safety glasses or full face mask. Avoid wearing contact lenses. Avoid repeated or prolonged skin contact. Wear overalls, waterproof boots and impervious alkali-resistant gloves (e.g., nitrile, PVC, rubber, neoprene). Tuck overalls inside boots and seal with duct tape to reduce risk of masonry dust entering boots. Remove protective clothing and wash exposed areas with soap and water prior to eating, drinking or smoking. Take special care to ensure that cuts/abrasions or irritated skin are not exposed to this product. It is also important to ensure that wet concrete does not become trapped within gloves, boots or clothing leaving concrete in contact with the skin for extended period of time may cause skin burns.

5 ECOLOGICAL INFORMATION General Environmental effects Wet concrete is considered to be harmful in the environment when in a soluble form.this is primarily due to the high ph of the product Water contaminated with this product is highly alkaline and should not be allowed to enter the environment. TOXICOLOGICAL INFORMATION Acute Effects Ingestion Ingestion of this product may cause gastrointestinal irritation. Eye contact Contact with wet (unhardened) concrete, mortar, cement mixtures or concrete dust can cause effects ranging from irritation to serious eye damage/burns and blindness. The ph of the mixture is >12. Note: the level of irritation/damage is dependent on the quantity of the dust, the ph, and the length of time exposed. E.g., if dust is washed out of the eye immediately, effects will be minor. However, if dust or wet concrete is left in contact with the eye, serious damage/blindness could result. Skin contact Contact with wet (unhardened) concrete, mortar, cement, or cement mixtures can cause skin irritation, severe chemical burns (third degree). Drying concrete is hygroscopic, i.e. absorbs water. It will draw water away from any material it contacts-including skin. This may cause irritation particularly in hot conditions or when sweating. Brief exposure to the skin (i.e., washed off immediately) will result in irritation. However, if the concrete or dust is left on the skin for an extended time (e.g., if inside boots or absorbed through overalls), burns to the skin are possible. Thickening of the skin and/or rash is also possible. Inhalation The wet concrete is not considered to be harmful if inhaled. DISPOSAL CONSIDERATIONS Restrictions Disposal method Contaminated packaging Local council and resource consent conditions may apply, including requirements of trade waste consents. Disposal of this product must comply with the requirements of the Resource Management Act for which approval should be sought from the Regional Authority. The substance must be treated and therefore rendered non-hazardous before discharge to the environment. There are no product-specific restrictions however, local council and resource consent conditions may apply, including requirements of trade waste consents. TRANSPORT CONSIDERATIONS Road and rail UN number Dangerous goods class No regulatory transport requirements. Not applicable. Hazchem code HSR002544: Construction Products (Subsidiary Hazard) Group Standard 2006.
