• Prepare and handle fluxes, lead-bearing materials, cupels, crucibles, parting solutions and other materials using approved methods and contamination-control practices.
• Run blanks, certified reference materials, duplicates and checks, and report non-conforming or unusual results immediately.
• Report abnormal fusion behaviour, poor slag separation, cupellation problems, prill losses, contamination concerns and equipment issues.
• Carry out sample preparation, wet chemistry, instrumental support or other technician-level lab duties when required, after completing the required training, competency and authorization.
• Record sample, batch, QC, equipment and result data in approved worksheets, forms, LIMS or other systems.
• Inspect, clean and troubleshoot fire-assay equipment, maintain work areas and follow lead control, hot-work, chemical handling and waste segregation rules.
