Box 122, Seven Hills) 2. HAZARDS IDENTIFICATION Classified as HAZARDOUS SUBSTANCE according to the criteria of Safe Work Australia Classified as DANGEROUS GOODS by the criteria of Australian Dangerous Goods Code (ADG Code) for transport by road and rail. Risk phrases: Safety phrases: R36/38; Irritating to eyes and skin Additional risk: spilt product may render surface very slippery. S36: Wear suitable protective clothing, S37: Wear suitable gloves, S39: Wear eye/face protection, S24/25: Avoid contact with skin and eyes. 3. COMPOSITION/INFORMATION ON INGREDIENTS Reference in AICS: YES Name CAS Number Proportion Polyaluminium Chloride to 60% Water To 100 % 4. FIRST AID MEASURES Eye contact: Flush with water for 15 minutes. Seek medical attention. Revision Date: Print Date: Page: 1 of 5

2 Skin contact: Inhalation: Ingestion: Remove contaminated clothing. Flush affected areas with soap and water. Remove from source of mist, allow patient to stabilize breathing in fresh air. If symptoms persist seek medical attention. Rinse mouth with water. Do not induce vomiting. If in doubt seek medical advice. 5. FIRE FIGHTING MEASURES Extinguishing media: Compatible with water, foam, CO2 and dry chemical. Fires can be attacked with extinguishers to suit local flammable/combustible materials Flash point (ºC): Material is non-flammable and non-combustible. Auto ignition point (ºC): Not applicable. Explosion Limits in Air (% by volume): Not applicable. Special Procedures: None. Unusual hazards: None known. Conditions to avoid: None known. Materials to avoid: Corrosive to most metals. Reacts violently with Potassium Decomposition products: Severe overheating may produce hydrogen chloride gas and aluminium oxide once water has been driven off. Hazardous polymerization: Will not occur. 6. ACCIDENTAL RELEASE MEASURES General Response: Clean Up Procedure: Personnel involved in the clean-up should wear appropriate protective clothing as listed in section 2. Slippery when spilt. Spillage into waterways will result in some lowering of the ph and the formation of aluminium hydroxide, which has a very low toxicity. Prevent drain or sewer contamination with absorbent such as sand or sawdust etc. Collect for disposal. Hose final trace residues to drain. 7. HANDLING & STORAGE Handling: Storage: Observe good personal hygiene practices and recommended procedures. Wash thoroughly with soap and water after handling. Do not store in metal containers. Store in labelled, corrosion resistant containers that are approved for dangerous goods. Store in a cool place away from strongly alkaline materials 8. EXPOSURE CONTROLS / PERSONAL PROTECTION National Exposure Standards Engineering Controls: None Established Good general ventilation should be sufficient for most conditions. Local exhaust ventilation may be necessary for some operations Personal Protective Equipment: Respiratory Protection: None required. General exhaust ventilation should be adequate. Eye Protection: Safety Glasses Skin and body protection: Disposable latex gloves, overalls or apron as appropriate. Rubber boots can be used in wet conditions but mainly as protection from the water Revision Date: Print Date: Page: 2 of 5

PHYSICAL AND CHEMICAL PROPERTIES Appearance: Clear to slightly greenish yellow solution Odour: None Boiling point (ºC): >100ºC Melting point (ºC): Not available Specific Gravity (H 2 O = 1): at 25ºC ph: at 25ºC (undiluted) Vapour pressure (kpa): Not applicable Relative vapour density: Not applicable Volatile by weight (%): Roughly 50 to hexahydrate form Solubility in water: Completely miscible Evaporation rate: Not applicable 10. STABILITY AND REACTIVITY Chemical Stability: Stable. Conditions to avoid: Store away from strong alkalis and Cyanides of Class 6.1. Decomposition products: Severe overheating may produce hydrogen chloride gas and aluminium oxide once water has been driven off. Hazardous polymerization: Will not occur. 11. TOXICOLOGICAL INFORMATION Acute Toxicity: Oral: Inhalation: Irritation: Skin: Eyes: Chronic Toxicity: Threshold limit value: LD50/oral/rat > 3311 mg/kg Product is not volatile. Mist or aerosol could cause irritation to mucous tissue. Skin irritant. May cause skin irritation with prolonged contact Irritation and redness. Possible corneal injury possible due to low ph and corrosive nature Moderately toxic by ingestion. An experimental teratogen. Corrosive and irritating to tissue 2 mg/m3 based on Al (roughly 0.25 mg/m3 based on actual product (Ref.: ACGIH, soluble Aluminium salts) 12. ECOLOGICAL INFORMATION Ecological Information Environmental fate and distribution Not a persistent pollutant; can cause coagulation of solids in aqueous suspension, especially when highly diluted by the water in which the solids are suspended. Aluminium compounds are common in most soils and are the principle components of Bauxite and Gibbsite, which are common, naturally occurring minerals. When diluted by copious quantities of water (for example, to the point that the concentration is less than about 100 grams per cubic meter), this product will hydrolyze rapidly to form aluminium hydroxide, which can be expected to become a part of the natural soil profile if not recovered. When not highly diluted with water, this product may be slow to hydrolyze and may form a mixture of partially soluble aluminium species and heavy floc of aluminium hydroxide. Until further diluted, this mixture could affect marine life by clogging sensitive respiratory mechanisms in a similar fashion to muds and clays and possibly by toxic effects that are not yet well understood.

4 Ecotoxicity: Bioaccumulative Potential: This product is used as a coagulant in water treatment and may cause finely divided solids to settle out rapidly from aqueous streams, depending on other factors such as ph and ionic strength. It may influence ph control as this material in the raw state has a ph of roughly 4, and it may also add to solids loading in filter cakes and present as a compressible cake. In large quantity this product is likely to make filter cakes "slimy" and wet. This can also cause "blinding of filter cloths" but these will normally respond to hosing or rinsing off. Does not bio accumulate. 13. DISPOSAL CONSIDERATIONS Waste disposal method: Refer to local waste disposal authority. This product can be neutralized with alkali to form a mixture of aluminium hydroxide and the chloride salt of the alkali. The resulting mixture is nonhazardous provided the resulting ph is between roughly 5 and TRANSPORT INFORMATION This product is classified as a Dangerous Goods classification. As a Class 8 substance, it must be separated from other placard loads of Dangerous Goods as follows: Store 12 meters from Dangerous Goods of Class 1 or 7 and 4.3 or 5 Store 24 meters from Cyanides of Class 6.1 UN No: 1760 HAZCHEM: 2X DG CLASS: 8 Poison Schedule: None Packaging Group: III EPG: REGULATORY INFORMATION This product is to be found in the public AICS database. 16.
