In the agricultural sector, health management for workers involved in pesticide application is crucial. Pesticides can adversely affect workers' health if not managed properly. Particularly, depending on the type of pesticide, there is a risk of health damage from inhalation or skin absorption. Measuring the work environment is essential for assessing the concentration of harmful substances during pesticide application and implementing measures to improve the work environment. Our work environment measurement service helps enhance safety in pesticide application and protect the health of workers. 【Usage Scenarios】 - Health management for agricultural workers engaged in pesticide application - Establishing appropriate work environments based on the type of pesticide - Risk assessment in pesticide application 【Benefits of Implementation】 - Reduction of health damage risks for workers - Compliance with labor safety and health laws - Strengthening of corporate safety management systems

Our company conducts Third Management Category Measurements (Respiratory Area Measurements). According to the Occupational Safety and Health Act, starting from April 2024, if the evaluation results of the work environment measurements correspond to the Third Management Category and are deemed difficult to improve by a work environment management specialist, it will be mandatory to implement exposure prevention measures by wearing respiratory protective equipment. A work environment measurement specialist will plan and conduct measurements after hearing the work situation from the business operator in advance. Additionally, we will prepare an opinion document from a work environment management specialist, which is necessary for reporting to the Labor Standards Inspection Office. [Measurement Examples] ■ Measurement of dust during lime bulk bag filling operations ■ Measurement of lead during bridge paint removal operations ■ Measurement of dichloromethane during metal product degreasing operations ■ Measurement of paint components such as xylene during painting operations *For more details, please download the PDF or feel free to contact us.

At the Analysis Center Co., Ltd., we conduct "Exterior Wall Adhesion Material Surveys." Pyrolysis GC/MS analysis (Py-GC/MS) is a method that analyzes the decomposition products generated by rapidly heating a sample using GC/MS to identify the main components. It is effective for determining the types of polymer compounds such as plastics and rubber. In this case, we present an example of component analysis conducted on a small amount of black viscous material adhered to an exterior wall using pyrolysis-GC/MS analysis (Py-GC/MS). [Pyrolysis-GC/MS Analysis (Py-GC/MS) Example] - From the exterior wall adhesion material, 1-butene and several low polymers of isobutene were detected as pyrolysis products. - The adhesion material was determined to be a copolymer of isoprene and isobutylene (butyl rubber). - Butyl rubber is widely used as a water stop agent for concrete. - It is inferred that the exterior wall adhesion material is a result of the degradation of the water stop agent on the exterior wall, causing it to seep out. *For more details, please download the PDF or feel free to contact us.

Our company conducts "Investigation of the Causes of Resin Material Failure (Creep Fracture)." When cracks or breaks occur in resin products, various fracture morphologies such as ductile fracture and brittle fracture can be observed on the fracture surface. In this case, we will introduce an investigation example of a resin product that was damaged due to creep fracture. The product was used in a high-temperature environment and experienced failure within 1 to 2 years of use. The fracture surface revealed fibrous patterns characteristic of creep fracture, formed by the elongation of the resin material. Based on the characteristics of this fracture surface and the fact that the product was used under high temperatures, it was inferred that the damage was caused by creep fracture. [Creep Fracture] ■ A phenomenon where, under high temperatures or in environments with significant temperature changes, a constant stress causes the material to undergo plastic deformation over time. ■ Creep fracture in resin materials can occur even at relatively low temperatures, such as room temperature, and becomes more pronounced as the temperature rises. *For more details, please download the PDF or feel free to contact us.

Our company conducts "Investigation of the Causes of Resin Material Damage (Fatigue Fracture)." When cracks or breaks occur in resin products, various fracture surface morphologies such as ductile fracture and brittle fracture can be observed on the fracture surface. In this case, we will introduce an investigation example of a resin product that was damaged due to fatigue fracture. In the observation case of a broken polycarbonate (PC), shell-like patterns (beach marks) were observed on the fracture surface. Such patterns are characteristic of fatigue fractures. Fatigue fracture refers to the phenomenon where repeated stress is applied to resin, leading to failure. Based on the characteristics of the fracture surface, it was inferred that the damage was caused by fatigue fracture due to the application of repeated stress. [Investigation Methods] ■ Visual or microscopic observation of the appearance ■ Preparation of samples for magnified observation ■ Magnified observation using a scanning electron microscope (SEM) *For more details, please download the PDF or feel free to contact us.

Due to localized deterioration occurring in the bathtub of a general residence, we were requested by the residents to investigate the cause and countermeasures, so we conducted a site survey. As a result of the inspection, multiple adherent substances were visually identified at the positions indicated by sticky notes on the bathtub, which were considered to be the cause of the deterioration. These adherent substances were all irregularly shaped and exhibited a brown color, measuring approximately 0.5 to 1 mm in size. We collected these brown adherent substances on-site and conducted elemental analysis using an electron probe microanalyzer (EPMA/EDS). The main constituent elements detected were iron and oxygen, which contribute to the brown color, leading us to conclude that the adherent substances were rust. Based on the analysis results, we proposed and implemented cleaning with a rust remover, successfully removing the brown adherent substances and restoring the bathtub. 【Elemental analysis results of the brown adherent substances by EPMA/EDS】 ■Detection intensity - Elements detected with strong intensity: Oxygen (O), Iron (Fe) - Elements detected with medium intensity: Carbon (C), Titanium (Ti), Calcium (Ca) - Elements detected with weak intensity: Silicon (Si), Copper (Cu), Chlorine (Cl), Zinc (Zn), etc. *For more details, please download the PDF or feel free to contact us.
