Enviro Safe is a "hydrocarbon refrigerant". In plain English, that's Propane! A small leak in the evaporator will fill the passenger compartment with enough propane gas fumes to blow all the windows out of the vehicle, and kill, or at least severely burn the occupants.

Be sure the purchase of this type of refrigerant includes a good life insurance policy!
