5K Support Co., Ltd. (Headquarters: Yokohama City, Representative: Yoshimasa Nakano) has announced "Grasp, Notify, Record" as its three principles for on-site heatstroke prevention, ahead of the full-scale hot season this summer. In workplaces like construction and manufacturing, where working in high-temperature environments is unavoidable, heatstroke prevention needs to evolve beyond mere "awareness-raising" to a system that can detect anomalies, take action, and leave records.
The Three Principles for On-Site Heatstroke Prevention advocated by 5K:
1. **Grasp:** Comprehensively understand not only the environmental risks of the site but also changes in the individual vital risks of each worker.
2. **Notify:** Appropriately notify not only the individual but also management of signs of danger, preventing oversights.
3. **Record:** Preserve records not only of risk changes but also of patrol and voice-check histories as an organization, preparing for recurrence prevention and accountability.
**Introducing 5K means "just a few changes to what you do on-site":**
* **Worker:** Wears a smartwatch. After work, places the watch in a charging box to charge.
* **Foreman:**
* **At start of shift:** Inquires about workers' attendance and physical condition, inputs into smartphone. Checks WBGT corrected value and gives instructions.
* **During work:** Checks WBGT value of the work area and workers' heatstroke risk on smartphone screen and gives instructions.
* Inputs results of patrol voice-checks into smartphone (with bulk check button).
* **Supervisor:** Checks the foreman's smartphone screen via smartphone or PC and gives instructions as needed.
With the introduction of devices (from 100,000 yen per site), visualization and recording of heatstroke risk are automated! "Heatstroke Prevention Checklist" is also automatically generated and printable.

In site safety measures, the most dangerous thing is to "think you're taking measures." As severe heat is expected again this summer, not just the presence or absence of measures, but whether they are actually implemented, will determine the quality of a company's safety management.
In conjunction with this announcement, 5K Support plans to release an introduction guide and heatstroke prevention checklist for customers who inquire. We will widely disseminate this content as a proposal to advance a culture of safety in the workplace, rather than just a product introduction.
**Comment:**
"Heatstroke countermeasures are not complete simply by introducing facilities and equipment. Grasping abnormalities at the site, notifying at the necessary timing, and leaving records. Only when these three are aligned can we say that measures are 'being implemented.' 5K will take on the challenge of creating new standards required for workplaces this summer."
