Abstract: The invention relates to methods and arrangements for creating a safe working space in the upper part of an elevator shaft. A position of an elevator car in the elevator shaft in relation to a plurality of safety levels in the elevator shaft may be monitored, where each safety level is associated with a separate clearance of the elevator car from a ceiling of the elevator shaft.
