Human Factors; Procedure
Upon boarding the plane I saw the B Flight Attendant using a portable dust buster like vacuum to clean the cabin carpeting. I didn't know it at the time; but this was his personal device. After we took off and began service; I looked at it again and realized that if the device had a thermal battery fire; there was no way it would have fit into a containment bag. Prohibit Crewmembers from using/bringing personal battery powered devices that are too big for a containment bag on board the airplane.
B737 Flight Attendant reported that a crewmember brought onboard a portable battery powered vacuum cleaner that would not fit into a fire containment bag.
