**[Amendment to the Labor Safety and Health Act]** In January 2022, there was a legal amendment regarding fall arrest equipment, and interest in ensuring safety in high-altitude work has increased. This system utilizes RFID technology with radio waves and magnetic fields to detect whether "safety belt hooks are being used" within a designated area and alerts the site to encourage workers to properly use fall arrest equipment. **■ System Overview** 1. Set up the "Area Setting Device" at the high-altitude work site. * The rope is highly flexible, allowing it to be laid out freely on-site to form an area. It is designed for outdoor use and is excellent in dust and water resistance. 2. Workers will wear the "IC Tag-equipped Hook Holder" and "Hook Magnet." * These can be easily attached to commercially available safety belts (owned by the customer). 3. The system detects whether safety belt hooks are being used within the area, and if they are not being used, it issues an alert. **■ Example of Utilization** This can be used in various high-altitude work sites. Examples include: bridge construction, residential construction sites, rooftop work, tower structures, and other work sites with risks of falls and accidents.

**[Amendment to the Labor Safety and Health Act]** In January 2022, there was a legal amendment regarding fall prevention equipment, and interest in ensuring safety during high-altitude work has increased. The Harness Alert detects when the safety belt hook is not detached from the hook holder and notifies users with an alarm (alert). It encourages high-altitude workers to use safety belts properly. *It can be easily attached to commercially available safety belts as an "add-on"!* **■ System Overview** 1. Set up the "Area Setting Device" at the high-altitude work site. The area setting device can be selected from three types: spot, rope, and wide, depending on the application. (For details, please refer to the basic information section.) 2. Workers will wear the "IC Tag-equipped Hook Holder" and "Hook Magnet." 3. Detect whether the "safety belt hook is being used" within the area. If the safety belt hook is not in use, an alarm (alert) will be issued. **■ Applicable Sites** General high-altitude work sites (bridge construction, residential construction sites, rooftop work)

**[Amendment to the Labor Safety and Health Act]** In January 2022, there was a legal amendment regarding fall prevention equipment, and interest in ensuring safety in high-altitude work has increased. This system utilizes RFID technology with radio waves and magnetic fields to detect whether "safety harness hooks are being used" within a designated area and alerts the site, encouraging workers to properly use fall prevention equipment. **■ System Overview** 1. Set up the "ON/OFF Area Setting Device" and "Receiving Alarm Device" at the high-altitude work site. * The ON Area Setting Device can be installed at the entrance of the site, allowing all areas beyond it to be designated as work areas. 2. Workers will wear the "IC Tag-equipped Hook Holder" and "Hook Magnet." * These can be easily attached to commercially available safety harnesses (owned by the customer). 3. The system detects whether safety harness hooks are being used within the high-altitude area, and if they are not in use, it issues an alert. **■ Example of Utilization** This system can be used in various high-altitude work sites. Examples include: bridge construction, residential construction sites, rooftop work, tower structures, and other work sites with risks of falls and accidents.

[Amendment of the Labor Safety and Health Act] In January 2022, there was a legal amendment regarding fall arrest equipment, and interest in ensuring safety in high-altitude work has increased. This system utilizes RFID technology with radio waves and magnetic fields to detect whether "safety harness hooks are being used" within a designated area and alerts the site, encouraging workers to properly use fall arrest equipment. ■ System Overview 1. Set up an "area setting device" at the high-altitude work site to designate a hazardous area. 2. Workers wear an "IC tag-equipped hook holder" and a "hook magnet." * These can be easily attached to commercially available safety harnesses (owned by the customer). 3. The system detects whether safety harness hooks are being used within the area, and if they are not being used, it issues an alert. ■ Example of Utilization… This can be used in various high-altitude work sites. Example sites: Bridge construction, residential construction sites, rooftop work, tower structures, and other work sites with risks of falls and accidents.

This system utilizes RFID technology with radio waves and magnetic fields to detect whether "safety harness hooks are being used" within a designated area and alerts the site to encourage proper use of fall protection equipment by workers. Using an IoT system, the hook usage status at the site can be monitored from a remote office. ■ System Overview 1. Set up the "Area Setting Device" and "IoT Box" at the high-altitude work site. 2. Workers wear the "IC Tag-equipped Hook Holder" and "Hook Magnet." * These can be easily attached to commercially available safety harnesses (owned by the customer). 3. Install a remote monitor box at the site office. 4. Detect whether safety harness hooks are being used within the area; if not in use, an alert is issued. 5. At the site office, the PC monitoring screen allows for checking the number of people in the area and whether safety harnesses are being used or not. If there are users not utilizing the harness, an alert is issued from the PC. ■ Example of Utilization… Can be used in various high-altitude work sites. Site examples: Bridge construction, residential construction sites, rooftop work, tower structures, high-altitude work vehicles.
