Safety system and method using a safety system

A safety system for localizing at least two objects with variable locations, the safety system comprising at least one control and evaluation unit, having at least one radio location system,

• wherein the radio location system has at least three arranged radio stations;
• wherein at least one respective radio transponder is arranged at the objects;
• wherein position data of the radio transponder and thus position data of the objects can be determined by means of the radio location system;
• wherein the position data can be transmitted from the radio station of the radio location system to the control and evaluation unit;
• and/or wherein the position data can be 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 transponders, with the radio transponders having identification, with a respective radio transponder being associated with a respective object, whereby the control and evaluation unit is configured to distinguish the objects;
• and
• with the control and evaluation unit being configured to associate a risk classification with each object at least in dependence on the position of the object with respect to another object.
