This unit describes the skills and knowledge required to implement a system of work for managing the use, handling, processing, storage, transportation and disposal of hazardous chemicals in the workplace; and to verify and validate the effectiveness of that system and the control methods in place against safety data sheet (SDS) requirements. The unit includes the application of the hierarchy of control measures, and applicable legislative requirements and licensing conditions imposed on the workplace in managing these hazardous chemicals.The unit applies to those accountable for ensuring that a system of work is in place for managing hazardous chemicals in a specified work area. The system of work to be implemented protects all those potentially at risk in the workplace from exposure to hazardous chemicals, including internal and external personnel. NOTES1. The terms ‘occupational health and safety’ (OHS) and ‘work health and safety’ (WHS) are equivalent, and generally either can be used in the workplace. In jurisdictions where model WHS laws have not been implemented, registered training organisations (RTOs) are advised to contextualise this unit of competency by referring to existing WHS legislative requirements.2. The model WHS laws include the model WHS Act, model WHS Regulations and model WHS Codes of Practice. See Safe Work Australia for further information.No licensing, legislative or certification requirements apply to this unit at the time of publication.
