Suitable trade training in flammable refrigerants is recommended prior to working on systems containing flammable refrigerants.
It is a requirement under work health and safety obligations that employers must ensure only competent workers work on air conditioners and other refrigeration systems, particularly those containing flammable refrigerants. Workers must be provided with appropriate information and training on the hazards and safe use of the specific refrigerants to which they could be exposed when performing installation, commissioning, service, repair, maintenance and decommissioning of refrigeration and air conditioning equipment.
A national unit of competency is available for A2L refrigerants (including R32) - VU22583 Class A2/A2L Flammable Refrigerants. It sits in the course – 22329 VIC Heating, Ventilation and Air Conditioning Services as an elective. To read more about this unit of competency visit https://training.gov.au/Training/Details/VU22583. To find registered training organisations visit www.training.gov.au
Check with the relevant state-based WorkSafe agencies and refer to the relevant material safety data sheets available from refrigerant wholesalers for specific safeguards when handling R32.
For further information on how to handle flammable refrigerants, refer to the Flammable Refrigerants Safety Guide (2018).
