(1) Removal of Volcanic Gases Sulfur dioxide and hydrogen sulfide gases are highly corrosive components that can corrode metals and cause equipment failures. To prevent equipment failures in volcanic areas, hot spring regions, and geothermal power plants, we manufacture and sell devices for the removal of volcanic gases. We have numerous achievements in volcanic tourist areas and hot spring regions. (2) Observation of Volcanic Gases We manufacture, sell, and maintain volcanic gas (hydrogen sulfide and sulfur dioxide) observation disaster prevention systems for volcanic tourist areas across Japan. (3) Research and Development of Volcanic Gases We are also engaged in research and development on volcanic gas themes in collaboration with universities conducting Earth science research. We present our research at volcanology conferences and have obtained patents through industry-academia collaboration with universities.

◆Effective for maintaining control panel equipment! You can reduce the frequency of maintenance!◆ It protects independently installed control panels and operation panels from internal corrosion caused by corrosive gases, preventing various losses due to troubles with control and electrical equipment inside the panel. Additionally, it can be adapted to control panels installed in various locations, such as those outside the instrument room or in areas where corrosive gases are present. 【Features】 ■Removal speed: Approximately 0.0 ppm (hydrogen sulfide) in about 400 seconds from 2.0 ppm ■Removal efficiency of over 95% (due to the airtightness of the control panel) ■Three types of MODELS available according to installation space ■Adsorbent modules use recycled paper, considering the environment *For more details, please request materials or download the catalog. ＊＊＊＊Exhibition Information＊＊＊＊ We will exhibit at the Sewerage Exhibition 25 in Osaka.

Volcanic gases are harmful to the human body, and gas accidents in volcanic areas have been reported. Following the eruption of Mount Ontake in 2014, the volcanic activity law was revised, and local governments have heightened their disaster prevention awareness regarding volcanic hazards. Volcanic gases can occur even when volcanic activity has subsided, posing a constant risk in volcanic regions. Even outside of volcanic tourist areas, there is always a risk of accidents due to volcanic gases at geothermal power plants and hot spring areas, making the monitoring of gas concentrations increasingly important for the safety of workers and customers. Our volcanic gas observation system is battery-operated, requiring no wiring work, and can be easily installed on-site. Communication uses mobile phone signals, so as long as there is mobile phone connectivity, it can be installed anywhere. The system can detect hydrogen sulfide gas (H2S) and sulfur dioxide gas (SO2), and gas data can be viewed on our website. Additionally, if gas concentrations rise, a gas alarm will be sent to the registered mobile phone's Line app, allowing for the sharing of gas concentration alerts within a Line group, thereby enhancing risk awareness among stakeholders.

This is a gas concentration meter with a logger that monitors low-concentration hydrogen sulfide gas wirelessly. It is specifically designed for low concentrations, making it effective for odor monitoring and tracking of corrosive gases. Hydrogen sulfide gas is rarely constant; it can rapidly increase in concentration in a short period due to wind direction and site conditions. Without continuous gas observation, it is very difficult to detect an increase in gas concentration. By installing our wireless low-concentration hydrogen sulfide gas concentration meter, continuous monitoring can be conducted, allowing for the capture of events where gas concentration rises.

Volcanic accidents remind us of the disaster caused by the eruption of Mount Ontake in 2014. However, the number of incidents related to volcanic accidents is overwhelmingly higher for those caused by volcanic gas poisoning, which are reported every year. Additionally, with the revision of the Active Volcano Law, local governments are now obligated to ensure the safety of tourists, increasing the importance of monitoring volcanic gases. This time, I will explain the mechanism by which volcanic gas (hydrogen sulfide gas) affects the human body. <Hydrogen Sulfide Gas H2S> Each cell that makes up our body requires respiration to live. Hydrogen sulfide gas has a property that allows it to easily dissolve into cells, causing respiratory distress and cell death, which leads to organ damage. Particularly, when lung cells are damaged, it can result in respiratory distress due to pneumonia or pulmonary edema, potentially leading to death. However, while high concentrations of hydrogen sulfide gas are dangerous to the human body, recent research suggests that low concentrations may have anti-inflammatory effects. This illustrates the fine line between poison and medicine. Perhaps the relief of fatigue after soaking in a hot spring is influenced by hydrogen sulfide gas?

The steam used for power generation at geothermal power plants contains hydrogen sulfide gas components. Even low concentrations of hydrogen sulfide gas, which do not affect the human body, can have a significant impact on the control equipment within the power plant. Hydrogen sulfide gas is invisible and has a heavy specific gravity, allowing it to infiltrate the electrical rooms and control rooms that manage the power plant through various pathways, leading to corrosion and failure of the equipment. JM Solutions Co., Ltd. provides total support for hydrogen sulfide measures within geothermal power plants, from investigation to countermeasures.

Volcanic accidents remind us of the disaster caused by the eruption of Mount Ontake in 2014. However, in terms of the number of volcanic incidents, accidents due to volcanic gas poisoning are overwhelmingly more frequent and are reported every year. Additionally, with the revision of the Active Volcano Law, local governments are obligated to ensure the safety of tourists, increasing the importance of monitoring volcanic gases. This time, I will explain the mechanisms by which volcanic gases (sulfur dioxide and sulfurous gas) affect the human body. <Sulfurous Gas and Sulfur Dioxide (SO2)> Harmful gases such as sulfurous gas and sulfur dioxide (SO2) damage the epithelial lining of the airways. This damage leads to the accumulation of inflammatory cells in the airways, causing inflammation. Due to this inflammation, the airways become sensitive, leading to airway constriction and triggering asthma attacks. The type of inflammation varies among individuals, resulting in allergic asthma or COPD. It is believed that various factors, including genetic and environmental influences, contribute to these types. Therefore, individuals have different tolerances to the gas, and there have been reports of asthma patients experiencing attacks even at low concentrations of around 0.2 ppm. Additionally, it is said that there are many undiagnosed asthma patients who are unaware of their condition.

Hydrogen sulfide gas is highly toxic, and concentrations of hydrogen sulfide gas above 10 ppm can lead to a diminished sense of smell, with headaches and nausea potentially occurring quickly. At high concentrations around 800 ppm, the risk of acute poisoning increases, and the possibility of death arises. However, even at low concentrations of hydrogen sulfide gas at the ppb (0.05 ppm) level, which have no impact on the human body, the effects on equipment can be significant. According to ISA standards, gas management for electrical control equipment is required to be below 50 ppb. Machinery is more vulnerable to hydrogen sulfide gas than humans, necessitating strict management.
