R410a is a blend of 2 refrigerants in a 50/50 mix of R-32 and R-125. R410a is being phased out (because of the r125) and soon no more new r410a equipment will be sold. R32 is slightly flammable. Some would say the R125 was included in the mix to help with the flammability others might imply it was so the manufacturer could patent r410a ... R290 aka propane is also flammable but it is not a fluorocarbon so the combustion byproducts are less nasty there are already leak detectors for it and it is readily available and not patented.
