USA: The Air Conditioning, Heating, and Refrigeration Institute (AHRI) has released the results of tests with A2L (lower flammability) refrigerants to assist in the training of firefighters.
The study was conducted following requests from the US fire service for data to be developed to identify hazards to the fire service personnel when responding to fire events in occupancies with the new A2L refrigerants.
The project, undertaken in cooperation with UL and the Firefighter Safety Research Institute (FSRI), tested and compared A2L refrigerants with A1 refrigerants in real-world situations. It included scenarios designed by fire service professionals to develop training for tactical consideration to demonstrate hazards that may be encountered by the fire service.
