Mixtures with air of the gas 1,1,1,2-tetrafluoroethane are not flammable at atmospheric pressure and temperatures up to 100 °C (212 °F). However, mixtures with high concentrations of air at elevated pressure and/or temperature can be ignited. Contact of 1,1,1,2-tetrafluoroethane with flames or hot surfaces in excess of 250 °C (482 °F) may cause vapor decomposition and t… Web•Low toxicity, similar to R-134a – Low acute and chronic toxicity – Significant testing completed •System performance very similar to R-134a – Excellent COP and Capacity, no glide • From both internal tests and OEM tests – Thermally stable and compatible with R-134a components – Potential for direct substitution of R-134a WebThe refrigerant toxicity classification has 400 ppm Occupational Exposure Limit (OEL) as the divide between higher and lower toxicity refrigerants. All widely used HFCs (except HFC-245fa), HFOs and HCFOs are classed as low toxicity, with OELs in the range 400 to 1000 ppm. R514A (containing dichloroethane) is classed as B1. getprocessmemoryinfo c#
