WebMar 8, 2024 · R-125 came about in the mid 1990’s and early 2000’s when the world was looking for replacements to the popular CFC and HCFC refrigerants R-502 and R-22. These previous refrigerants were found to be harming the Ozone layer and were phased out by the Montreal Protocol. R-125 was safe, it was cheap, and it was efficient. WebAll 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. The hydrocarbon refrigerants are classified as low toxicity. ASHRAE 34 also cites, in its refrigerant data and safety classification table, the toxicity category of the ...
