Respect of Humanity and Assurance of Comfortable Working Environment

Basic Approach

Safety and Health Policy

Structures and Systems

Aiming for zero industrial accidents, NGK introduced an Occupational Safety and Health Management System (OSHMS) in fiscal 2007 as a mechanism for the ongoing systematic implementation of safety and health activities based on company-wide safety and health policies.

Acquisition of Management System Certification (as of the end of fiscal 2016)

NGK Nagoya, Chita and Komaki Sites as well as Ishikawa Plant have acquired JISHA's OSHMS certification*.
Domestic Group companies NGK Adrec and Akechi Insulators have started taking action to acquire OHSAS 18001 certification.
Overseas Group companies

NGK Ceramics Suzhou, NGK Ceramics Indonesia, NGK Ceramics Polska and NGK Ceramics South Africa have already acquired OHSAS 18001 certification.

NGK Ceramics Europe, NGK Ceramics USA and NGK Insulators Tangshan have started taking action to acquire the certification.

* When requested by a workplace, the Japan Industrial Safety and Health Association (JISHA) and other certifying bodies evaluate the workplace's Occupational Safety and Health Management System (OSHMS) based on JISHA's OSHMS criteria, including whether it is properly introduced based on the guideline released by the Ministry of Health, Labour and Welfare, and whether it is operated properly to produce step-by-step improvement in safety and health performance. Those who meet the criteria can acquire the certification.


Enhancing Safety and Health Management

We promote the development of our Occupational Safety and Health Management System (OSHMS) and are striving for zero accidents. We have aimed for systematic and organizational improvement of occupational safety and health activities while operating a PDCA cycle.

External Certification on Safety and Health Management System

We promote the acquisition of safety and health management system certification, which is gaining importance globally, and incorporation of the system into operations.

Enhancing Safety and Health Activities

We disseminate information to each site and keep track of individual situations. Also, through auditing and provision of support, we strive to solidly improve the level of our safety and health activities.

Company-wide Deployment of 5S Activities

Teams formed in each workplace promote the establishment of team objectives and periodic times to conduct 5S activities: sort, set in order, shine, standardize and sustain the workplace.

Following Up with Employees Working Long Hours

We provide employees working long hours with ongoing opportunities to meet with industrial doctors for health consultations and exams.

Promoting Activities to Support Mental and Physical Health

We deploy ongoing activities focused on the Four Types of Care recommended by the Ministry of Health, Labour and Welfare.

Promotion of Experience-based Safety Education

We are seeing a growing number of accidents among workers with a shorter work history and those with less experience. In response, we have established training centers at three sites in Nagoya, Chita and Komaki, as well as at Ishikawa Plant, where trainees can actually experience risks. Establishing these centers in-house means that more workers can now take enhanced training. At each training center, we teach them the importance of compliance with safety rules while using simple devices that let trainees safely experience three kinds of risks: electric shock, being pulled into machinery and getting caught. We are also planning to set up a "Safety Dojo" (meaning Safety School), aiming to further enhance the experiential training and develop trainees' capacity to foresee risks.
