Abstract
An elevator system (1) including at least one refuge space (7, 8) and at least one light curtain (9). The at least one light curtain (9) is configured to detect at least one object in the at least one refuge space (7, 8) and produce at least one safety signal (21) indicating the presence of the at least one object in the at least one refuge space (7, 8). The system can be used to improve the safety in the at least one refuge space (7, 8) in the event that the usual safety procedures have either failed or not been followed.
