Examination of reliability and convenience of the Safeguarding Supportive System (SSS)-Experimental evidence at a company

We newly established risk reduction system, named “Safeguarding Supportive System (SSS)”, which is proposing to ISO. It is established to prevent human error and intentional unsafe behavior from mechanical side (hardware side). The SSS would reduce residual risks with appropriate ITC combination. We examined efficacy of the SSS at a rental company of portal workbench. We examined 1) whether RF-tag system was adequately operated by workers, 2) whether UWB-active-RFID system precisely monitored and captured workers movement and location in real time, and 3) whether gateway monitor system appropriately monitored entering into and leaving from the work zone. As results in the present study, there were no differences in relative ratio of correct count, safe failure and dangerous failure in zone A1 and those of B1. Time and trace of movement of workers were recorded by UWB active RFID system. Also, the system could be confirmed of state of the simultaneous works of more than one worker.
