Should I friend my coworker or not?

I have been working with this girl for a couple months now. When ever we work together we flirt, and have fun. I have asked others their opinion on how we act together and so far they all have told me that she is interested. The only problem is that the only time that I see her is when i work with her. which does happen quite a bit but lately they have been moving me around and have been having me help with stock since i am no stranger to manual labor. My biggest question now is if i should friend request her on Facebook or if that would be too weird?

Facebook would just be a helpful median for me.
