Education and training

At Dexerials, we regularly conduct education for occupational health and safety/disaster prevention, disaster drills, safety confirmation system practice, and education for the safe handling of chemical substances in heavy use in development and manufacturing sites. For new employees, we conduct firefighting training, disaster countermeasure training using actual outdoor fire extinguishers, and experiencing simulated natural disasters, etc. Foreman education regarding safety considerations at work sites is given to employees who become the new heads of work sites, and appropriate safety education is given at the right time to employees who are engaged in special types of work including forklift operation, and handling laser machinery and various powders. We also have created a location to increase the awareness and sensitivity of employees regarding safety by establishing a safety workshop to experience various dangers.

Emergency Response Drills

Inspection of utilization status of environment-related substances

we carry out an annual inspection of the usage status of environment-related substances, check the usage status of chemical substances including VOCs, and the preventive measures against environmental accidents. This allows us to continue our record of accident-free handling of organic solvents.

Solvent leakage response drill

Each plant carries out drills in line with its specific risk profile, and uses any shortcomings or issues identified as feedback to improve its response to leakage incidents. Repeated drills have worked so far to maintain the high level of responsiveness to leakage incidents.





Solvent leakage response drills at overseas business sites

At the Dexerials Group’s overseas plants, similar leakage drills are carried out periodically to improve employee skills.

Workplace Safety

At all sites, Dexerials regularly carries out risk assessments at each workplace. The various dangers at each workplace are extracted, categorized for the level of danger, improved and reviewed in a workplace safety PDCA cycle. The safety and hygiene committee regularly confirms the progress of risk assessments.
Also, in the Dexerials company-wide improvement activity “ADVanCE,” more than 500 safety improvement plans per year are submitted, so that all employees are always improving the workplace and implementing workplace safety countermeasures.

Equipment disaster prevention

Disasters can be separated into two types: “machinery” and “human.” We engage in disaster prevention activities on the basis of the idea that the elimination of these two factors is important to disaster prevention. In order to eliminate machinery disaster (i.e. unsafe status) and human disasters (i.e. unsafe actions), we engage in disaster prevention by reducing the level of “machinery” and “human” danger as we prioritize the elimination of dangers and risks from machinery by conducting danger and risk identification and analysis during the introduction and operation of machinery from the design and investigation stage. With regard to machinery that has already been introduced, we have introduced structure for the early-stage detection of abnormalities by conducting independent maintenance by the using department and various inspections in planned maintenance by the equipment specialist department. By appropriately such performing maintenance, we are striving toward the advance prevention of accidents. Also, we are taking initiatives to minimize damage during emergencies by conducting regular accident preparation training

In order to achieve this aim, we believe it is essential that all employees are physically and mentally healthy.
Dexerials will continue to promote workstyle reform and work on efforts toward creating an environment where our employees can demonstrate their abilities by maintaining their health and working safely. We will also promote health care of each and every employee in cooperation with the Dexerials Health Insurance Association.

Organization Structure for Health and Productivity Management

Physical examinations

Overwork physical examinations are conducted as a countermeasure against excess work in addition to regular physical examinations and special physical examinations based on the Industrial Safety and Health Act. Applicants over the age of 35 undergo thorough medical check-ups, which leads to the early detection and prevention of lifestyle diseases. Industry physicians check the results of the health diagnoses of all employees, and industry physicians and public health nurses conduct follow-up checks such as individual appointments and medical consultation promotion for recommended individuals. In addition, in cooperation with health insurance associations, in-company dental checks are conducted every year, and dentists provide check-ups and brushing instructions, which leads to the early detection or prevention of oral diseases among employees.

Pre-check-up Challenge

In order to enable employees and their family members to review their nutrition and exercise habits prior to physical examinations or medical check-ups and prepare by improving their condition, we held a campaign called “Pre-check-up Challenge” lasting for one month, which had 266 participants, including insured family members. In cooperation with the health insurance association, Dexerials is promoting health of employees and their family members.

Mental health initiatives

We are cooperating with health care offices, industry physicians and work sites on the prevention and early detection/ treatment of mental health issues among employees, support for various consultations from employees and those on a temporary leave of absence, and support for return to work.
Also, we are conducting in-depth initiatives such as self-care, line-care, and face-to-face support by industrial health staff, and we are engaging in mental health support for employees, and improvements to the workplace environment.

Stress checks

Based on the revised Industrial Safety and Health Act, all employees have been undergoing stress checks since 2016. The checks raise individual employees’ awareness of stress and how to deal with it. The health and safety committee also notifies industrial physicians of the results of group analysis. Furthermore, we focus on workplaces that have demonstrated issues, our HR and industrial health staff are discussing and conducting measures with workplace superiors, and we are monitoring changes and implementing the PDCA cycle. Going forward, we aim to understand issues through detailed analysis, and use this to improve workplaces in order to create pleasant workplace environments.

Mental health classes

All management level employees participate in an annual workshop held by industry physicians with regard to health-related laws that are of importance to managers, safety consideration responsibilities, and the role of managerial employees in mental health.
Moreover, considering that mental health management and early detection of unwellness are essential not only for managers but also for workplace leaders, Dexerials added a mental health management examination (Type II line care course) to requirements for promotion of middle-rank employees in fiscal 2019.

Mental health classes

External counselling

In order for employees to be rid of worries and to createa system for immediate consultation, a free external counselling office has been established. By establishing various consultation systems inside and outside the company with industry physicians, public health nurses and clinical psychologists, we promote mental health countermeasures in the “Four Cares” (self-care, line care, care from workplace healthcare staff and care from resources outside the workplace) as indicated in the Ministry of Health, Labour and Welfare’s guidelines for maintaining and promoting the psychological health of employees.

Quit-smoking activities

We promote quit-smoking activities from an environmental perspective, such as designating building interiors as no-smoking zones and establishing smoking hours, and we work with health insurance societies to run activities to support quitting smoking for staff that wish to do so. We cover all expenses for staff that attend clinics to quit smoking and 80% of participants in fiscal 2018 managed to quit.
Furthermore, the safety and hygiene committee, etc., regularly arranges lectures by industrial physicians about smoking and health, and conducts blood flow measurement and anti-smoking education on World No Tobacco Day.
Going forward, we will continue our anti-smoking activities with the aim of improving the health of our employees.

Health Support

Lunch at the company cafeteria is a relaxing time for the employees and it provides a venue for an important meal that forms the basis of health promotion. Company cafeterias at each site provide information about health, such as introducing healthy menus to promote staff health, providing low-calorie, nutritionally balanced menus, and providing table-top advertising and information.

Furthermore, we hold health events and health seminars through tie-ups with cafeteria operators at cafeterias.
At health events, employees gain an understanding of their own health status through blood flow measurement, bone density measurement, and simple locomotion checks, etc. and these initiatives provide employees with an opportunity to examine their lifestyle habits.

With regard to health seminars, we work with health insurance societies to hold RIZAP Health Seminars for employees to engage in enjoyable health improvement activities. Monthly yoga classes are held at the Nakada Plant with the aim of maintaining and improving health.
Furthermore, we conduct “healthy challenges” for employees and their families, in conjunction with health insurance societies. Employees and their families challenge themselves to improve their lifestyles and health, such as walking, quitting smoking, losing weight, and hand-washing and gargling for children.

In-house refreshment spaces

In order to be a company where employees can work with enthusiasm, and to create an environment and provide structure so that employees take an interest in their own health and grow together with the company, a space for refreshment and light exercise was set up at each sites.

Occurrence of Workplace Accidents

In fiscal 2018, eight workplace accidents occurred in the Dexerials Group. The accidents were all due to human error, notissues with equipment or safety management.
Whereas there were accidents that resulted in loss of work time due to careless mistakes by workers in fiscal 2017, there were no accidents that resulted in loss of work time in fiscal 2018 thanks to the initiatives to prevent workplace accidents.
We conduct investigations, analyses and improvements with regard to accidents that occur at the company as minor mistakes and near misses may lead to major accidents, and then we share the information throughout the company to prevent reoccurrence. While preventing serious accidents, we will carry out activities to eliminate human errors, and to find and eliminate risks such as dangers and health hazards in the workplace, and we will make further improvements to form safe workplace environments.
