Chemicals (DOCX 474KB) will assist you to review and revise the content of the mandatory focus area: Chemicals. Each focus area prescribes the scope of learning for the HSC and is drawn from the associated unit of competency. You will have studied one of these competencies, both of which address the scope of learning: AHCCHM201 Use chemicals under supervision or AHCCHM307 Prepare and apply chemicals to control pests, weeds and diseases.
