Cyclopentane in 134a Refridgerators

We just received a newer fridge in our intake and discovered there is something called "Cyclopentane" in it which appears to be better blowing agent for the environment. I need to to know whether it's safe or not to reclaim with the rest of the 134a we have. What alarms me about this gas is that it is highly explosive when mixed with air. Does anybody have any advice with this?

The cyclopentane should only be in the foam insulation and not the refrigerant. I asked my yard when I first saw this come through and they said it was no problem.
