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. We need to monitor the Wet Bulb Globe Temperature (WBGT) and share information with all stakeholders in real-time. Using the Weather Forecast Analysis Distribution System [Disaster Prevention Panel], we conducted predictions of the Wet Bulb Globe Temperature (WBGT) and installed weather observation equipment [N Sensor] on-site to monitor the WBGT. Additionally, by linking the Disaster Prevention Panel with business chat, we efficiently shared information with stakeholders.

Thank you for always watching. In recent years, abnormal weather has been increasing, and disasters caused by heavy rain and typhoons are unavoidable. However, anticipating "how to act" and "what measures to take" in advance greatly influences whether damage can be minimized.
