Abstract: A method using a safety system and a safety system for localizing at least one object, with varying locations, are provided. A radio location system has at least three arranged radio stations and at least one radio transponder is arranged at the object. Position data of the radio transponder and the object can be determined by means of the radio location system. The position data can be transmitted from a radio station of the radio location system to a control and evaluation unit which is configured to cyclically detect the position data of the radio transponder. A first inspection unit is connected to the control and evaluation unit, and the control and evaluation unit is checked by the first inspection unit.

Abstract: A safety laser scanner for securing the surroundings of at least one object has a first safety laser scanner with which a first defined reference target is associated and a second safety laser scanner with which a second defined reference target is associated. Each safety laser scanner includes: a light transmitter; a light deflection unit for a periodic deflection of the light into a scanning plane; a receiver for providing received signals in dependence on light remitted at articles present in the field of vision of the scanner; and an evaluation unit for evaluating the received signals with respect to the angle and the distance of the article and for providing a safety signal. Furthermore, the scanning planes of both scanners are aligned in a coplanar manner and the first scanner forms the second reference target and the second scanner forms the first reference target.
