5K Support starts providing cloud service for mandatory heatstroke countermeasures, integrating 'WBGT preventive measures', '3 types of alarms', and 'cloud recording'
5K Support has launched a new cloud service to visualize heatstroke risks using WBGT values and vital health checks. It aims to reduce management burdens in construction and manufacturing sites following the revised safety act.

This service combines:
- WBGT values of the workplace
- WBGT correction values by health condition check
to visualize "heatstroke risks". Preventive measures based on data can be executed.
When heatstroke risks and vital risks increase, three types of alarms are simultaneously reported to related parties.
Furthermore, on the cloud, it not only automatically records WBGT values but also automatically generates, records, and prints "Heatstroke Prevention Check Sheets".
It does not increase the burden on the site, such as recording by hand or calculating. Just introduce the device.
■ Background: Moving to a stage where "preventive measures and recording" are required due to mandatory regulations.
Under the revised Industrial Safety and Health Ordinance enacted on June 1, 2025, employers are required to take the following measures to discover workers at risk of heatstroke early:
- Risk assessment using WBGT
- Establishment of a preventive measure implementation system
- Creation of implementation procedures to prevent serious conditions
- Notification to relevant workers
In addition, the notification also indicates effective measures according to the site, such as workplace patrols, buddy systems, and the utilization of wearable devices.
Heatstroke measures have entered a stage where the question is whether daily preventive measures can be incorporated into operations, not just alarms right before onset.
However, the following issues have become apparent on-site:
- Only WBGT measurement
- Frequent alerts even after introducing heat accumulation sensors
- No records remain
Under these circumstances, according to the Ministry of Health, Labour and Welfare's announcement at the end of December 2025, the number of casualties due to heatstroke in the workplace was 1,681, the highest since 2005. Among them, there were many casualties with 278 in the construction industry and 337 in the manufacturing industry.
■ Service Features
1. Check changes in heatstroke risk every 5 minutes
Automatically calculates who is working at which workplace and at what heatstroke risk every 5 minutes, and displays it on a smartphone or computer screen.
When arriving at work, you can check the "WBGT correction value" reflecting the heat tolerance of each worker as a numerical value, which can be utilized for work placement.
During work, based on the visualized "heatstroke risk" of each person, appropriate preventive measures such as instructions to change work, change locations, or stop can be implemented. Furthermore, the results of calling out to workers can be recorded.
2. Reduce the risk of aggravation with 3 types of alarms
Sends out 3 types of alarms by combining vital information such as heatstroke risk, heart rate, blood oxygen, and activity level, along with the results of health checks during patrols.
Rest alarm: Sent based on the relationship between working hours and rest hours according to WBGT
Yellow alarm: Sent from heatstroke risk, high heart rate, low blood oxygen, and health check results
Red alarm: Sent from abnormal heart rate, abnormal blood oxygen, and health check results
Does not depend on a single indicator, multiple...
