Abstract: Task—To provide a two-hand switch device that requires only a small load for each operation cycle. Means to Achieve the Task—The device comprises a left hand RF antenna placed in such a position as to enable a communication with the first RFID tag worn on the pre-determined position of the left hand of the worker only when the left hand of the worker is placed in a pre-determined left hand safe position, a right hand RF antenna placed in such a position as to enable a communication with the second RFID tag worn on the pre-determined position of the right hand of the worker only when the right hand of the worker is placed in a pre-determined right hand safe position and an output signal generating means for generating an output signal according to signals received by the left hand RF antenna and the right hand RF antenna.

Abstract: Task—To provide a worker safety management system that can adapt itself to changes in the conditions of the workers and the machines in a flexible manner and can finely manage the safety of the worker. Means to Achieve the Task—Worker safety is managed by using safety management information stored in an ID tag. The safety management information includes a work area code indicating a work area permitted to the corresponding worker and a danger avoiding capability code indicating a danger avoiding capability of the worker. The danger avoiding capability indicated by the danger avoiding capability code is determined from a worker skill of the corresponding worker that is evaluated in a standardized manner from past work experience of the corresponding worker and credits earned in a safety education program, and a specific degree of danger in the work area permitted to the worker.
