Thanks guys for the prompt reply.
As far as those positing the notion of it being common sense, you are preaching to the choir but I recently had a discussion with a guy who didn't seem to believe it was an issue at all.
Apparently, we have a Captain who is big on not having paper clips lying around on the pedestal and this F/O was kinda ridiculing the guy's position.
I told the F/O that I share that captain's position but other than having a common sense opinion for it, I wanted to find something "published" as he didn't seem convinced of this hazard.
Thanks
