Classified as a Hazardous Substance according to the criteria of Office of the Australian Safety and Compensation Council (previously NOHSC, the National Occupational Health and Safety Council).
Risk phrases: R36/38; Irritating to eyes and skin
Additional risk: spilt product may render surface very slippery.
Safety phrases: S37: Wear suitable gloves, S39: Wear eye/face protection, S24/25: Avoid contact with skin and eyes.
Eyes (contact): Flush with water for 15 minutes. Seek medical attention.
Skin (contact): Remove contaminated clothing — flush affected areas with soap and water.
Inhalation (breathing): This product has negligible vapour pressure and can only be inhaled as a mist or aerosol. Remove from source of mist, allow patient to stabilise while breathing in fresh air. If symptoms develop, seek medical attention.
Ingestion (swallowing): There is no immediate danger. Give water to drink. Consult a physician and let the physician know that the patient has swallowed a concentrated, mildly acidic aluminium salt solution that is not a scheduled poison, containing an organic polyeletrolyte that is also not a scheduled poison. Do not induce vomiting unless directed to do so by the physician.
Flash point (ºC): Material is non-flammable and non-combustible.
Auto ignition point (ºC): Not applicable.
Explosion Limits In Air (% by volume)
Lower: Not applicable.
Upper: Not applicable.
Extinguishing media: Compatible with water, foam, CO2 and dry chemical. Fires can be attacked with extinguishers to suit flammable and combustible materials within the surrounding area.
Special Procedures: None.
Unusual hazards: None known.
Conditions to avoid: None known.
Materials to avoid: May emit some chlorine gas when in contact with very strong oxidising agents; some heat liberated when in
contact with strong acids.
Decomposition products: Severe overheating may produce hydrogen chloride gas and aluminium oxide once water has been driven off.
Hazardous polymerisation: Will not occur.
Refer to Section 8 for personal protective equipment.
Steps to be taken in case material is released or spilled: If spilled, the affected area may become slippery. Prevent drain or sewer contamination with absorbent such as sand or sawdust etc. Collect for disposal, hose final trace residues to drain. Spillage into waterways will result in some lowering of the pH and the formation of aluminium hydroxide. Although aluminium hydroxide has a very low toxicity, aquatic life may be adversely affected during the brief period of hydrolysis leading to its formation. This period may last up to 30 minutes.
Storage in metal drums is not recommended, although stainless steel may be used on a temporary basis if stored at room temperature.
EFFECTS OF EXPOSURE
Eyes (Contact): Irritation and redness.
Skin (Contact & absorption): May cause skin irritation with prolonged contact.
Inhalation (breathing): No vapour, product is not volatile. Mist or aerosol could cause irritation to mucous tissue.
Ingestion (swallowing): Nausea & vomiting; could have systemic effects
SPECIAL PROTECTION INFORMATION
Respiratory protection: None required in normal operations. Wear appropriate breathing apparatus if application generates mist.
Ventilation: Local exhaust recommended.
Protective gloves: PVC or rubber.
Eye protection: Chemical goggles or safety glasses.
Other protective equipment: Not required, aprons and rubber boots can be used in wet conditions but mainly as protection from the water.
Safety profile: A mild human skin irritant.

Further toxicity information on product:
Toxicity profile: This material is not a persistent poison, and neither this material, nor aluminium salts in general, nor the specific polyelectrolyte used as an ingredient in this product are listed in the Standard for the Uniform Scheduling of Drums and Poisons (Vol. 20). Aluminium hydroxychlorides would be expected to hydrolyse on contact with water to form aluminium hydroxide, which has a very low toxicity and would eventually becoming a part of the eco-system. Some reduction in pH may occur on hydrolysis.
Threshold limit value: 2 mg/m3 based on Al (Ref.: ACGIH, soluble Aluminium salts). More toxicity information on the organic ingredient can be found in Section 12.
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 hydrolyse rapidly to form aluminium hydroxide, which can be expected to become a part of the natural soil profile if not recovered. The formation of aluminium hydroxide is part of the process of hydrolysis of the aluminium salt. During hydrolysis, which
may last up to an hour, the product is known to be fairly toxic to aquatic life, including fish. This toxicity diminishes following hydrolysis as the aluminium hydroxide disperses into the environment.
Similarly, any toxicity effects due to the organic component of this product will diminish significantly within 30 minutes as the product binds to suspended particles and dissolved organic carbon. As a result, any toxicity tests on water that contains no suspended solids or natural organic matter would tend to overestimate its true aquatic toxicity, as the suspended solids and natural organic matter would tend to greatly reduce its effective concentration. Nevertheless toxicity effects on fish are reported. The following toxicity information is available for the organic component of this product:
Test: acute toxicity, freshwater (OECD Test 203) Duration: 96 hour
Species: Rainbow trout
LC50: 1 to 10 mg/L
This product will remain as an effective coagulant almost indefinitely, although it may suffer some loss of flocculating performance over a period of a year or more (that is, it may become progressively less effective in bringing about rapid aggregation of newly formed floc). Its use in clarification of turbid waters is encouraged in preference to disposal where possible.
Waste disposal method: If disposal is necessary, refer to local waste disposal authority. This product can be neutralised with alkali to form a mixture of aluminium hydroxide and the chloride salt of the alkali. This is best done after diluting the product at least ten times with water. The resulting mixture is non-hazardous providing the resulting pH is between roughly 5 and 9.
This product does not carry a Dangerous Goods classification.
