Thank you for always watching. This time, I would like to address the topic of heatstroke. Some of you may be thinking, "What? It's still spring, and we're talking about heatstroke?" However, considering that the number of heatstroke cases tends to increase around May, it's not too early to start preparing now. *For more details, please visit our company website.

In recent years, natural disasters have been frequent in Japan. Every year, some region in the country is struck by disasters, suffering significant damage. In particular, there has been a notable increase in heavy rain disasters in recent years, with rising frequencies and durations of heavy rain occurrences, as well as an increase in the number of landslide disasters. This document introduces key points that site managers should be aware of regarding how to confront the dangers of heavy rain at construction sites in order to mitigate damage. Please feel free to download and review it. [Contents] ■ Introduction ■ Chapter 1: Case Studies of Damage from Localized Heavy Rain ■ Chapter 2: Is it Only Linear Precipitation Belts?

This time, I would like to explain the criteria for stopping work with cranes, specifically the "average wind speed of 10 m/s," including how the wind blows and what kind of effects it can have, as well as touching on the differences between average wind speed, instantaneous wind speed, and maximum wind speed. 1. What does "average wind speed of 10 m/s" mean? 2. What are the differences between "average wind speed," "instantaneous wind speed," and "maximum wind speed"? 3. Conclusion 1. What does "average wind speed of 10 m/s" mean? The way the wind blows varies in strength and can be influenced by terrain and nearby structures. According to the Japan Meteorological Agency, an "average wind speed of 10 m/s" is described in forecasting terms as "a somewhat strong wind." *For more details, please visit our website or feel free to contact us.

Thank you for always reading. This time, we will deliver an article related to heatstroke. In the previous article, we explained the heat index (WBGT) as an indicator to measure the risk of heatstroke, stating that high temperature alone does not define "heat." WBGT is an index that quantifies the risk of heatstroke based on "temperature," "humidity," and "radiant heat." However, the factors contributing to heatstroke are not limited to the outside air. The work being performed at that time and the clothing being worn also significantly affect the risk of heatstroke. Therefore, to prevent heatstroke, it is necessary to consider two factors: "correction based on clothing combinations" and "WBGT standard values according to physical work intensity." In this article, we will introduce these two aspects. *For more details, please visit our company website.

As autumn deepens, the morning and evening chill becomes more severe day by day. During this time, you often hear the phrase "the cooling becomes severe due to radiative cooling" in weather forecasts, don't you? This time, I would like to talk about that "radiative cooling."

As we approach the end of October, the weather has completely turned to feel like autumn. Many people might be taking advantage of the pleasant weather to engage in sports or travel, right? On my days off, I enjoy hiking with friends as a hobby. One topic that often comes up is "the weather in the mountains can change rapidly." This time, I would like to explain the reasons behind that.

We will provide useful information about the weather, incorporating explanations from our company's meteorologists! The peak of midsummer has passed, and in Kitakyushu, air conditioning is no longer needed at night. Autumn is finally approaching, and it seems to be becoming a more comfortable season, doesn't it? Now, this time, we will introduce the "autumn rain front," which has been frequently mentioned in the news lately! Please check the details from the link below! https://product.sysmet.jp/kishou/k_119.html

The Föhn phenomenon refers to the occurrence where "moist air from the windward side rises over a mountain peak and, upon descending on the leeward side, becomes a warm and dry wind." For more details, please download the PDF.

We will provide useful information about the weather, incorporating explanations from our company's meteorologists! The mornings and evenings have become cooler, and the season is gradually becoming more comfortable! With the significant temperature differences, please take care to manage your health. Now, in the previous discussion, we talked about "What is the autumn rain front?" but this time, I would like to talk about what a "front" actually is. In meteorology, a "front" refers to the boundary line (front surface) that forms when cold air (a mass of cold air) collides with warm air (a mass of warm air), which is the line that touches the ground.

On the night of December 15th, the temperature in the Kanto region and other areas rose sharply above 10°C.

The humid rainy season has arrived, and many people may be thinking about measures against heavy rainfall, such as linear precipitation zones. However, it is easy to get caught up in the heavy rain and not fully grasp the threat of lightning, isn't it? It is said that the voltage of a lightning strike can reach 100 million volts, which is equivalent to 1 million times that of household electricity. In Japan, it is reported that there are more than 1 million lightning strikes in a year during peak times, making the risk higher for professions that often work outdoors, such as civil engineering and construction. As a private weather company, we believe it is important to share knowledge related to weather with everyone, even in a small way, and we have created a guidebook titled "Preventing Lightning Damage! (Part 1) Basic Knowledge and Evacuation Action Guide." We encourage you to take a look at it and utilize it for ensuring safety in the workplace or as training materials. *For more details, please visit our website or feel free to contact us.*

When it comes to June, the first thing that comes to mind is, of course, "the rainy season." It can often be a gloomy time, with the daily humidity and heat, the growth of mold, and disruptions to transportation… making it easy to feel down. Now that the rainy season has begun in various regions this year, I would like to revisit the topic of "the rainy season." Table of Contents 1. Why is it called "the rainy season" in the first place? 2. Why does it rain for such a long time during the rainy season? 3. Is the way it rains different in Western and Eastern Japan? 4. Important disaster prevention information regarding heavy rain 5. Conclusion *For more details, please visit our website or feel free to contact us.

This time, I will discuss important indicators used in port operations. Depending on the site environment, offshore construction is easily affected by waves and wind, making it particularly necessary to carefully consider weather conditions in cost management and labor management. Therefore, in offshore construction, there is an important keyword known as "utilization coefficient." This time, we will take a rough look at this "utilization coefficient." 1. What does "utilization" mean? 2. Calculation of the utilization coefficient 3. Concept of the utilization coefficient 1. What does "utilization" mean? First, "utilization" refers to the state in which machinery and equipment have been delivered to the construction site. The number of days from when the equipment is delivered to when it is removed is referred to as "utilization days." Additionally, the construction period (excluding preparation and cleanup) includes not only the days when work is performed (working days) but also non-working days (holidays, safety training days, days of inclement weather, etc.). The remaining days in a year (365 days) after excluding these non-working days constitute the annual "operating days" of the machinery and equipment. *For more details, please visit our website or feel free to contact us.

In recent years, there have been more 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 handbook is divided into two parts: "Basic Knowledge Edition" and "Prevention Measures Edition." In this Basic Knowledge Edition, we will clearly convey the current state of heatstroke and the knowledge necessary for creating effective systems. Please make use of this material for safety measures specific to your site, as well as for training materials and safety conference resources.
