SUMMARY The following details will be published in the NICNAS Chemical Gazette: ASSESSMENT REFERENCE APPLICANT(S) CHEMICAL OR TRADE NAME HAZARDOUS INTRODUCTION VOLUME USE LTD/1754 A S Harrison & Co Limited Polymer in OLI 9000.m ND ≤ 100 tonnes per annum Fuel Additive *ND = not determined CONCLUSIONS AND REGULATORY OBLIGATIONS Hazard classification Based on the available information, the notified polymer is not recommended for classification according to the Globally Harmonised System for the Classification and Labelling of Chemicals (GHS), as adopted for industrial chemicals in Australia, or the Approved Criteria for Classifying Hazardous Substances (NOHSC, 2004). Human health risk assessment Under the conditions of the occupational settings described, the notified polymer not considered to pose an unreasonable risk to the health of workers. When used in the proposed manner, the notified polymer is not considered to pose an unreasonable risk to public health. Environmental risk assessment On the basis of the reported use pattern, the notified polymer is not considered to pose an unreasonable risk to the environment. Recommendations Occupational Health and Safety Guidance in selection of personal protective equipment can be obtained from Australian, Australian/New Zealand or other approved standards. A copy of the (M)SDS should be easily accessible to employees. If products and mixtures containing the notified polymer are classified as hazardous to health in accordance with the Globally Harmonised System for the Classification and Labelling of Chemicals (GHS) as adopted for industrial chemicals in Australia, workplace practices and control procedures consistent with provisions of State and Territory hazardous substances legislation should be in operation. Disposal The notified polymer should be disposed of to landfill. Emergency procedures Spills or accidental release of the notified polymer should be handled by physical containment, collection and subsequent safe disposal.
Vapour Pressure 2.3 x 10-7 kPa at 25 °C EC Council Regulation No 440/2008 A.4 Vapour Pressure. Remarks Determined using a vapour pressure balance Harlan (2008) Water Solubility ≤ 3 x 10-3 g/L at 20 °C OECD TG 105 Water Solubility. EC Council Regulation No 440/2008 A.6 Water Solubility. Remarks Column Elution Method. The test substance was reported as OLI9000.m, which was a product containing the notified polymer. This is considered acceptable since the test substance preparation for the column method is expected to remove any liquid medium before determination of the solubility. The determined water solubility of 3 mg/L was reported for the test substance. The water solubility for the notified polymer it is not expected to be higher than the determined ≤ 3 mg/L based on the nature of the column test. Innospec (2010c) Surface Tension 34.75 mN/m OECD TG 115 Surface Tension of Aqueous Solutions. Remarks Concentration: Neat Innospec (2009) Flash Point 158.5 °C (pressure unknown) EC Council Regulation No 440/2008 A.9 Flash Point. Remarks Pensky-Martins closed cup flash point apparatus was used. Innospec (2010d) Autoignition Temperature 380 ± 5 °C EC Council Regulation No 440/2008 A.15 Auto-Ignition Temperature (Liquids and Gases).
