The invention relates to a safety arrangement of an elevator and a method for implementing safety spaces in an elevator shaft. The elevator comprises an elevator control system (2), an elevator motor (25), a power supply circuit (1) of the elevator motor, and at least one mechanical stopping appliance (26, 48) for preventing movement of the elevator car (28) in the elevator shaft (27). In the method according to the invention information is read with the control unit (3) from the sensors (7, 7', 8) that measure the position of the landing door (20) of the elevator and possibly information is read from the sensors (29) that measure the position of the door of the elevator car. If it is detected that more landing doors than the door of the elevator car are open, the control unit is switched to the person in the elevator shaft mode and information about the person in the elevator shaft mode is sent with the control unit (3) to the elevator control system (2).
