   • Wash and drain resin tanks thoroughly in line with environmental protection practices.
   • Pump resin from delivery truck to tank, monitor to ensure successful transfer and complete appropriate documentation.
   • Wash area surrounding tank clear of any spillage in line with organisational safety procedures and environmental protection practices.
4. Operate effluent system
   • Clean effluent tanks regularly in line with environmental protection practices.
   • Add settling agents to effluent tanks according to required quantities and allow for settling.
   • Remove solids and dispose of in line with organisational safety procedures and environmental protection practices.
5. Complete operator maintenance
   • Follow organisational safety procedures to lock out equipment.
   • Check treating mechanisms for operational effectiveness.
   • Check, adjust and maintain vat and oven temperatures in line with manufacturer’s recommendations.
