We will introduce a case where there is a suspicion of sick house syndrome, and environmental measurements containing volatile substances were conducted.
Due to suspicion of sick house syndrome, environmental measurements containing volatile substances were conducted. As a result of the measurements, no volatile substances such as formaldehyde were detected. Instead, it was found that carbon dioxide levels were significantly above the standard value, revealing that insufficient indoor ventilation was the cause of the headaches. 【Overview】 ■Issues - There was suspicion of sick house syndrome. ■Solutions - Conducted environmental measurements containing volatile substances. - It was found that carbon dioxide levels were significantly above the standard value, and insufficient indoor ventilation was determined to be the cause of the headaches. 【Causes of Headaches】 Various factors can contribute to symptoms such as headaches. Changes in atmospheric pressure, odors, sounds, light, flashes, taste, stress, etc. *For more details, please refer to the PDF document or feel free to contact us.

basic information
This is an introduction to a case study investigating dust dispersion conditions to ensure the safety of workers. 【Overview】 ■Issue Dust dispersion during the manufacturing and processing of walls by a house manufacturer. ■Solution In the actual work environment, multiple locations were measured at equal intervals to understand the areas where worker exposure was believed to be the highest, as well as the average dispersion state in the workplace, allowing for an accurate report on the dust dispersion conditions in the work environment. ■When conducting dust analysis in work environment measurements, it is necessary to measure "free silica!" Free silica is a collective term for three types of minerals (quartz, cristobalite, and tridymite), known as crystalline silica. All of these minerals are composed of silica and oxygen, and inhaling this stone dust can lead to a disease known as silicosis. Silica is commonly found in everyday life, such as in soil and sand. Quartz can be detected in construction materials, so caution is necessary. Whether "free silica" can be detected depends on the performance of the X-ray diffraction analysis equipment. The X-ray diffraction analysis equipment used by our company is equipped with a semiconductor detector, demonstrating excellent capability in the trace analysis of free silica in airborne dust, which is the most critical aspect of occupational exposure.
