Station 8 / Squad 8 is located at 7643 Santa Monica Blvd in Los Angeles, in West Hollywood, about 25 miles north of Station/Squad 127, which served as the fictional home of Station/Squad 51. Unlike 51, 8 is an actual Station number and is still active today. Before being featured in this episode, Station 8 was featured in the TV show, Rescue 8, which ran for two season's between 1958 and 1960. The show was about two LA County Firefighters who were trained as rescue specialists. They were played by Lang Jeffries (Bill Lappin) and Jim Davis, who is arguably most famous for playing Jock Ewing in the original Dallas.

She also refers to the location that the Paramedic calls are coming into, by its official designation; Base Station.
