Elements and Performance Criteria

1. Prepare to work with CO² refrigerant
   • Work health and safety (WHS)/occupational health and safety (OHS) hazards, risk control methods, relevant standards, codes and legislation are obtained and applied in accordance with workplace procedures
2. Electrical and non-electrical isolation are identified and carried out to prevent creation of hazards from loss of machine/system/process control in accordance with workplace procedures
3. Tools and equipment needed for the work are checked for safety and correct functionality in accordance with workplace procedures and regulatory requirements
4. Apply safe work practices in using CO²refrigerant
   • CO² refrigerant workplace procedures and work instructions for controlling risk are followed
5. Accidents, fires and emergencies are responded to in accordance with workplace procedures and within scope of own responsibility in a manner that minimises risk to personnel and equipment
6. Follow workplace procedures for hazard identification and risk control of CO²refrigerant
   • CO² refrigerant hazards are identified, risk assessed and control measures implemented and monitored through active participation in the consultation process with work supervisor and others
7. WHS/OHS incident records are completed in accordance with regulatory requirements and workplace procedures
8. CO² refrigerant workplace instructions and training are followed in accordance with workplace procedures
