Flight Crew Overcame Equipment Problem
Human Factors
Prior to departure; Operations Agent showed me paperwork showing oxygen cylinder onboard as HAZMAT and showed it denoted on the Release that it was carried in Bin A. I ask her if I need to sign said paperwork and she said no; after looking over the document there was no place for PIC (Pilot in Command) signature. The Operations Agent said all she needed was to show me that it was onboard and she keeps the paperwork. We fly to ZZZ1 uneventfully; and finish our trip.
Air Carrier Captain reported not receiving flight crew copy of Hazmat documents from Operations Agent delineating the oxygen cylinders on board.
