**[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)

The Harness Alert is a safety system that issues warnings to workers who forget to use hooks while working at heights, raising awareness of safety. By adding the Harness Alert Cloud, it transforms "invisible hazards" occurring on-site into "visible safety data," enabling preventive safety management to prevent accidents before they occur. Alarm history is automatically sent to the cloud via LTE communication, allowing administrators to check the site conditions from anywhere using a browser. By accumulating and analyzing data for each worker, it supports the understanding of danger trends and proactive safety measures. 【Features】 - Remote monitoring function: Check the safety harness usage status from a remote location - LTE communication compatible: Send on-site information to the cloud in real-time - Automatic alarm history recording: Automatically record the time of alarm occurrence, the relevant worker, and the area of occurrence - Reporting function: Automatically generate reports on hook usage status - Alert notification function: Notify administrators of alarms when hooks are not used - Browser compatibility: Viewable from a browser without the need for dedicated software - Easy installation: Can start operation with just the installation of additional equipment to existing systems *For details, please refer to the PDF document or contact us.

The "Worker Proximity Detection System" by Yoshikawa Industries supports the awareness of heavy machinery and workers, aiming to reduce the risk of contact. By installing a "detection device" on the heavy machinery and having the worker carry a "tag," an alarm will sound when the two come within a certain distance (which can be set). 【Features】 - One detection device can detect in 360 degrees (all directions). - The detection range can be set from 3m to 12m in 1m increments. - It detects by circumventing obstacles, so it also alarms for head-on approaches. - Alarms can be activated for both the heavy machinery and the worker (please choose a tag with alarm functionality). - It can be installed regardless of the manufacturer, type, or power source of the forklift (compatible with 12v/24v/48v). - The system and peripheral devices can be developed and customized according to customer requests. - With a variety of optional products, you can use it more comfortably! - By using the "Non-Detection Area Setting Device," you can designate the driver's seat as a "non-detection area." This allows for use without removing or turning off the tag, making it popular in environments where drivers change frequently.
