Sanitisation system and method of sanitising in an enclosed space

A sanitisation system for an enclosed space 30 having a touch surface 32, 36 which is contacted, in use, by multiple users of the enclosed space 30. The sanitisation system comprises: an occupancy sensor 42 configured to detect a user occupancy status of the enclosed space 30 and to output an occupancy signal which corresponds to the user occupancy status; a lighting system (44, fig. 2) comprising at least one lighting device configured to irradiate the touch surface with a beam of ultraviolet light 62, 64; and a controller configured to receive the occupancy signal and to control the lighting system. In accordance with a cleansing schedule and in response to the occupancy signal, the touch surface 32, 36 is irradiated with the beam of ultraviolet light 62, 64 only when the enclosed space 30 is unoccupied. The cleaning schedule may be initiated at a frequency depending on the occupancy rate within the enclosed space 30. The enclosed space 30 may be an elevator car 12 or toilet cubicle.
