Narrative:

During deicing procedures in the deicing area; we were informed that a fuel cap had been found on the ground by our aircraft. A few minutes later it was determined that the fuel cap had been knocked to the ground by deice spray; and had previously been sitting on our wing.I asked the deice crew to pass the cap through the cockpit window; and we returned to the gate where I was able to determine that it was; in fact; the fuel cap for our aircraft. I called maintenance; who ensured the cap was serviceable and reinstalled it. We then fueled; deiced; and departed.this was a case of gross negligence on the part of fueling personal. Not only should the fueler have informed us of the disconnected fuel cap chain; but leaving it on the wing presented a severe safety hazard. Under the right conditions the cap could have been ingested by our #2 engine.I related the incident and my concerns to the fuel supervisor; who I hope will take corrective action on this matter.
