The new F-Gas European Union (EU) Legislation requires car manufacturers to design their vehicles for application of low Global Warming Potential (GWP) refrigerant gasses. Low GWP substitutes to R-134a for Mobile Air Conditioning (MAC) application have to be assessed based on their potential for human exposure in terms of toxicity and flammability. Among the current potential candidates, the present paper deals with the flammability risk assessment of HFO-1234yf. This joint DuPont and Honeywell proposal is a Hydro-Fluoro-Olefin, 2,2,2,3 Tetrafluoroprop-1-ene.
