This unit describes the skills and knowledge required to identify and control hazardous chemicals in the workplace. It requires knowledge of the potential hazards associated with chemicals and how to work safely with them. It involves supporting workplace safety by communicating information about hazardous chemicals using established consultation methods.The unit applies to those who participate in identifying chemicals as part of their WHS responsibilities, which are in addition to their main duties. It applies to hazardous chemicals with the potential to harm human health, which may be solids, liquids or gases; pure substances or mixtures. When used in the workplace, these substances can generate vapours, fumes, dusts and mists.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.
