As the HVACR industry progresses towards lower GWP refrigerants, technicians are facing a new challenge of working with mildly flammable refrigerants classified as ASHRAE Safety Classification A2L. This shift necessitates a change in best practices and regulations for technicians who are accustomed to dealing with non-flammable A1 refrigerants. The use of these new refrigerants requires specialized knowledge and training to ensure safe handling and disposal. Technicians must be aware of the potential risks and hazards associated with A2L refrigerants and take appropriate measures to mitigate them. As the industry continues to evolve, technicians need to stay up-to-date with the latest regulations and guidelines to ensure safe and efficient operation.
