Elements and Performance Criteria

1. Prepare for heat treating
   • Review work order and where required check with appropriate personnel.
   • Identify and obtain type and quantity of material for heat treatment.
   • Select appropriate personal protective equipment and check for operational effectiveness.
   • Plan heat treating process cycles in line with work order.
2. Dry material
   • Use equipment in line with organisational safety procedures, manufacturer’s instructions and environmental protection practices.
   • Complete pre start-up equipment checks to ensure operational effectiveness and set heating temperature and humidity for optimal product recovery.
   • Adjust oven settings to suit process cycles and material condition, and monitor continually.
   • Follow emergency shutdown procedures in response to oven alarm.
   • Prepare racks containing materials of consistent processing condition and allowable range of thickness and load into oven, maximising space.
   • Assess material visually and measure moisture levels to ensure specified outcome.
   • Tag or mark processed racks and take samples of material for testing.
   • Record and report heat treating process to appropriate personnel.
3. Redistribute material
   • Regrade material in line with industry standards.
   • Direct material to storage or processing operations in line with organisational procedures.
   • Reject and dispose of defective material in line with environmental protection practices.
   • Clean work area in line with organisational safety procedures.
4. Complete operator maintenance
   • Follow organisational safety procedures to lock out equipment.
   • Check heat treating mechanisms for effective condition.
   • Adjust and maintain temperature and humidity settings, water drainage, atomising sprays and fans in line with manufacturer’s recommendations.
   • Keep oven clear of dust and debris in line with organisational safety procedures.
   • Record and report equipment faults and maintenance requirements to appropriate personnel.
