The Occupational Safety and Health Research Institute has previously released a new survey: Carbohydrates were detected in semiconductor factories at three companies, including Samsung.
Describe:
Air Filter can be divided into air filter for machine equipment, air filter for clean room and dust filter for preventing air pollution.
Characteristics and advantages:
The three major types of Air Filters form their own structures and filtering effects because of their different protection areas, but they have one thing in common, that is, air is used in circulation media, as well as other types of air filters, such as air filters in hydraulic systems. Known as the hydraulic tank air filter; From a technical point of view, people wear masks are also air filters, the former protects the machine (hydraulic system), the latter protects human health.
Classification and applications:
Machinery and equipment type of air filter: automotive air filter, Air Compressor Air Filter, their shape is generally cylindrical air filter. Clean room air filter: workshop clean use; Biomedicine production, chemical electronic chip production, operating room and other industries, their shape is generally square junior high efficiency plate filter. Air filter is used to filter smoke dust from steel plant, cement plant, chemical plant and so on, and to control the discharge of dust remover. Their shape is cylindrical filter tube and filter bag.

Researchers from the beginning of 2009, which lasted three years, conducted investigations at five production lines and four assembly lines at factories of Samsung, Hynix Semiconductor Inc. and Fairchild Semiconductor. The above result.
Park Jung-sun, the director of the institute, said: "Our findings are significant and the production lines at these factories were tested to contain a certain amount of carcinogens such as benzene, arsenic, and formaldehyde, even though their contents are not sufficient. Carcinogenic, but already enough worrying. These factories must do their best to minimize these levels."
According to the results of the study, some production lines and assembly lines accidentally produced benzene that can cause leukemia, which is less than 1 part per million and still within an acceptable range. However, the detected arsenic content on the tap water line was 0.061 mg/m3, which was much higher than the acceptable maximum value of 0.01 mg/m3. Arsenic can cause lung cancer. Taking into account the health of employees, these factories must take immediate measures.
In July last year, six young employees of the Samsung chip factory suffered from leukemia and other blood diseases. For this reason, Samsung had to hire a well-known US environmental consulting company to investigate these cases. The results showed that the employee's illness was not related to the chip factory. According to reports, Samsung also organized an expert committee to conduct a self-examination on the existence of cancer risk in the factory the previous year. The latest findings undoubtedly gave Samsung a punch.
