A method using a safety system for localizing at least one object, the safety system having at least one control and evaluation unit, and having at least one radio location system,

• wherein the radio location system has at least three arranged radio stations;
• wherein at least one mobile device having at least one radio transponder is arranged at the object;
• wherein position data of the radio transponder and thus position data of the objects are determined by means of the radio location system;
• wherein the position data are transmitted from the radio station of the radio location system to the control and evaluation unit,
• and/or wherein the position data are transmitted from the radio transponder to the control and evaluation unit,
• wherein the control and evaluation unit is configured to cyclically detect the position data of the radio transponder,
• with the objects being persons or mobile objects,
• with the radio transponders having an identification, with a respective radio transponder being associated with at least either one person or one mobile object, with the control and evaluation unit being configured to distinguish the persons and mobile objects, and
