In light of the recent increase in heatstroke-related fatalities due to extreme heat, the Labor Safety and Health Regulations will be revised starting June 1, 2025, making heatstroke prevention measures mandatory in the workplace. This is particularly important in the construction industry, where outdoor work is common, and it is expected that each worker is mindful of heatstroke prevention on a daily basis. However, to safely navigate summer work, it is essential to implement heatstroke prevention measures not only at the individual level but also as a systematic approach. Sysmet Co., Ltd. has created a "Heatstroke Prevention Handbook" as a private meteorological company. This handbook is divided into two parts: "Basic Knowledge" and "Prevention Measures." The latter part, which focuses on prevention measures, introduces examples of heatstroke prevention strategies that can be realized through the "Natural Disaster Prevention System ZEROSAI," which allows for centralized management of weather information observation, forecasting, and notification. Please feel free to utilize this handbook as training material or for safety meetings, tailored to the safety measures of each site. *For more details, please visit our website or feel free to contact us.*

Due to the mandatory implementation of heatstroke prevention measures in the workplace, we have seen an increase in inquiries regarding heatstroke at our company. Among these, we have received many requests to "measure the heat index (WBGT) in accordance with JIS standards." To conclude, the observation of the heat index (WBGT) in accordance with the Japanese Industrial Standards JIS Z 8504 can be achieved by utilizing the black globe thermometer from the Natural Disaster Prevention System ZEROSAI. - Real-time heat index (WBGT) management in the cloud, combined with pinpoint weather forecasting - Notifications via electronic display boards and business chat (LINEWORKS, direct, Wowtalk, Microsoft Teams) when threshold values are exceeded - Centralized management of various observation equipment information such as wind speed, rainfall, water level, noise, and vibration - API integration available *For more details, please visit our website or feel free to contact us.

We will introduce examples of the implementation of the Natural Disaster Prevention System ZEROSAI (Registration Number QS-150021-VE) in civil engineering and construction work in the construction industry. It can be utilized not only for safety measures but also for creative ideas and technical proposals. [Before Implementation] Due to the proximity of the sea and the lack of obstructions, there were many sudden gusts of wind, making it difficult to determine whether it was safe to continue work. <Issues> - Checking weather apps for work decisions took time, and there was a time lag in informing the entire site. - Delays in deciding to halt work due to strong winds led to cases where work continued while risks were present. We introduced our Natural Disaster Prevention System ZEROSAI along with the optional three-color signal light. For more details, please visit our website or download the PDF.

In recent years, there have been increasing opportunities to feel summer-like heat starting around May. This raises concerns about heatstroke. Particularly in the construction industry, where outdoor work is common, each worker is likely to be mindful of heatstroke prevention on a daily basis. However, to safely navigate summer work, it is important not only to have individual measures but also to implement systematic heatstroke prevention strategies. Sysmet Co., Ltd. has created the "Heatstroke Prevention Handbook: Basic Knowledge Edition" as a private weather company. This book is structured in two parts: "Basic Knowledge Edition" and "Utilization Edition." The Basic Knowledge Edition clearly conveys the current state of heatstroke and the knowledge necessary for creating effective systems. Please feel free to use it as training material or safety conference resources for safety measures specific to each site. *For more details, please visit our website or feel free to contact us.*

[Before Implementation] We want to share information about heatstroke on-site and improve safety measures for workers. <Challenges> It is necessary to obtain weather information that is relevant to the site.
