Lift

A lift was a device used to vertically transport people or goods between the levels of a building. Mel and Pex used a lift in Paradise Towers to try and get to floor 304. However, the cleaners overrode the controls and had the lift alternate between floors 173 and 174. Pex kicked the controls and the lift plummeted down to the basement. There they managed to get it working again and made it to floor 304. (DW: Paradise Towers)

The lifts at New New York Hospital disinfected their occupants, as the Tenth Doctor and Rose Tyler experienced, much to the latter's dismay. (DW: New Earth)
