Safety system and method using a safety system

A method using a safety system for localizing at least one person or at least one object in a monitored zone, the safety system having least one control and evaluation unit, having at least one radio location system, and having at least one spatially resolving sensor for the position determination of the person or object,

• wherein the radio location system has arranged radio stations;
• wherein at least one radio transponder is arranged at the person or object;
• wherein position data of the person or object can be determined by means of the radio location system;
• wherein the position data can be transmitted from the radio stations of the radio location system to the control and evaluation unit,
• and at least presence data of the person or object can be determined by means of the spatially resolving sensor,
• wherein the monitored zone has a plurality of sectors and a plurality of passage zones between the sectors,
• wherein at least one spatially resolving sensor is associated with each passage zone,
• with the control and evaluation unit being configured to cyclically compare the position data of the radio location system and the presence data of the spatially resolving sensor in each respective passage zone and to cyclically form status information for the sector.
