Abstract: An elevator system (1) including at least one refuge space (7, 8) and at least one sensor (9). The at least one sensor (9) is configured to detect weight in the at least one refuge space (7, 8) and produce at least one safety signal (21) indicating the presence of weight 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. For example, if for some reason the elevator system (1) has not been placed into a safe state before a maintenance worker (10) accesses the at least one refuge space (7, 8), the system will detect them and can produce at least one safety signal immediately indicating their presence in the at least one refuge space.
