The Gumi Plant obtained the Healthy Workplace ‘Navi Certification’ by Gumi. The Navi Certification System is a high-quality health brand project of the healthy city that Gumi has conducted since 2011. The system selects a workplace that satisfies all areas of individual health resources as well as physical working environments to enhance health and safety of workers among manufacturing workplaces located in Gumi, certifying it as the Healthy Workplace Navi. The certified workplace receives a certification plaque from Gumi, partial support of certification screening costs of occupational health and safety management system (Kosha18001), and benefits of internal and external corporate publicity. The Gumi Plant plans to continue promoting the nonsmoking campaign and health promotion activities, and create a high-quality healthy workplace.
