Education and Training for Safety

Special education and training for safety and health

Article 59, Paragraph 3 of the Industrial Safety and Health Law states that when a worker is to be assigned to dangerous or harmful operations, the employer shall provide that worker with special education for safety and/or health concerning those operations.
Article 36, Paragraph 1 of the Ordinance on Industrial Safety and Health identifies "work involving the replacement of grinding wheels or their test runs at the time of replacement" as a form of dangerous or harmful work.
Therefore special safety and/or health education must be performed when an employer assigns a work to "work involving the replacement of grinding wheels or their test runs at the time of replacement."
