It is neither flammable nor explosive. Its toxicity is small, and sinre it is a halogen minute leaks can be readily detected by the halide torch method or the electronic detector method (6.Il) •. The leakage rate is kept down by the high molecular weight. The critical temperature is moderate (471°K). From a Refrigerant 11 pressure enthalpy diagram (6.I9) we have
