Human Factors
I was working the B position doing a passenger count when I noticed our final passenger being boarded in a wheelchair and a man behind him carrying a full size oxygen bottle. I immediately said to the flight attendant working the A position we should check our manuals because I'm fairly certain they are not approved and are considered HAZMAT. We also informed our Captain what was going on and he began checking manuals and making the appropriate phone calls. In the meantime the wheelchair assistant proceeded to bring on 3 additional full size oxygen bottles for the passenger at which point we asked them set them down in the boarding area and go get a gate agent.Eventually the passenger was told it was against FAA regulations to have an O2 bottle on the aircraft; he was informed he would need an oxygen concentrator; and removed from the aircraft. The flight continued as normal; however; during flight a female passenger flagged me down to express her concern as a passenger that HAZMAT was allowed through security and past however many [Company] representatives before it was noticed by us. I told her I agreed and would be filling out the appropriate paperwork to report the issue.
Air carrier Flight Attendant reported a passenger went through security and was in the process of boarding with four full size oxygen bottles in violation of HAZMAT regulations and policies.
