The special regulations for preventing exposure during metal arc welding and similar operations have been revised.
"Welding fumes" and "basic manganese oxide" will be added to the specified chemical substances (Category 2 substances).
This is based on the recommendations of exposure limit values for manganese and its compounds by the American Conference of Governmental Industrial Hygienists (ACGIH) and the European Commission Scientific Committee (EC) by recognizing that "welding fumes" and "manganese and its compounds" are likely to have different toxicities and health effects, thus positioning "welding fumes" as an independent specific chemical substance (Category 2 controlled substance). For the time being, it will not be classified as a special controlled substance, and it will be reconsidered when findings regarding carcinogenic substances become clear. Overall, this revision requires not only general ventilation in the workplace but also the appointment of a work supervisor who has completed the "Specific Chemical Substance and Tetraalkyl Lead Work Supervisor Skills Training," as well as measures such as measuring the concentration of welding fumes in the air using a sampler. *For detailed content of the column, please refer to the related links.
