Work Safety & Health ; Health Management

Policy and Basic Approach

Under its Responsible Care Policy, the Nippon Kayaku Group is undertaking various initiatives related to health promotion and occupational safety and health, so that every employee may work safely and healthily and output their abilities to the fullest.
We are aiming for zero serious accidents and hazards, and, with the objective of eliminating unsafe actions, are treating the strengthening of 30-second patrols and promotion of fixed-point inspections as key Responsible Care issues. We believe it a company’s responsibility to work towards accident-free and hazard-free workplaces, and guarantee the safety and security of employees.
We also believe the physical and mental health of employees to be linked to organizational vitality and improved productivity, and thereby indispensable in the quest to raise stakeholder satisfaction. That is why we not only develop explosion-prevention measures for the handling of chemicals at work, but mental health care and lifestyle improvement activities also.
With a view to achieving our KAYAKU Vision 2025 (KV25) Medium-term Business Plan Targets, the entire Group will continue uniting under the motto of “Safety trumps everything else!” as it provides further activities pertaining to health improvement and occupational safety and health.

System

Under its Declaration on the Environment, Health, Safety and Quality, the Nippon Kayaku Group has set up an Environment, Safety and Quality Management Committee.
We have appointed our Director In-Charge of the Technology Unit as our person responsible for Group health and safety management. Our Responsible Care and Technology Unit serves as the office for our Environment, Safety and Quality Management Committee. Taken together, these two entities form our structure for linking with related departments.
Our Environment, Safety and Quality Management Committee fixes Responsible Care policy and plans, and discusses improvements to work safety and health conditions, health promotion activities, fire and disaster prevention, and the creation of a comfortable workplace. Important committee matters connected to workplace safety and health, and health management, are, subject to Sustainable Management Meeting approval, reported to the Board of Directors.
We have also established an Environmental Conservation Managers Committee, linked to our Environment, Safety and Quality Management Committee. This committee is chaired by our Responsible Care and Technology Manager and has its office within our Responsible Care and Technology Unit. It links up with the Environmental Conservation Department managerial representative stationed in each workplace and group company, shares information and issues relating to workplace safety and health management as well as health promotion activities across the Nippon Kayaku Group or within individual group companies, and discusses key groupwide matters and issues before engaging in improvement initiatives.
Nippon Kayaku has also formed cooperative links with the Nippon Kayaku Health Insurance Association and formed the Health Collaboration Liaison Committee with the aim of providing effective and efficient support to employees and their families in their quests to maintain and improve their health. This Liaison Committee exchanges information, reviews reports, and holds discussions on matters related to health improvement.

Initiatives: Work Safety and Health

Risk Assessment Safety Inspections Conducted

When we commence new operations, introduce new equipment, or change existing operations or equipment, we conduct Risk Assessment Safety Inspections and carry out safety policies based on their results. We also conduct HAZOP* Safety Assessments on our chemical processes and reaction equipment to analyze the primary factors behind hazards.

  • *HAZOP: Hazard and Operability Study: A method of safety assessment for chemical plants which allows for extraction and assessment of the potential hazards associated with chemical reactions

Joint Initiatives with the Labor Union on Occupational Safety and Health

In the form of an internal audit based on the annual plan, Nippon Kayaku conducts Environment, Safety and Health Diagnostic Checks for each business site and a section of Group companies. In principle, these Diagnostic Checks are conducted with the participation of either the Labor Union Head Office or the relevant union branch of the inspected business site or Group company.
The Environment, Health and Safety Diagnostic Check team, comprised of the Environmental Safety Division, environment safety managers and labor union members, confirms progress reports and activities related to Responsible Care policies through discussion, document reviews and onsite inspection patrols. By assessing problematic points including from union perspectives are we able to devise improvements to safety and health standards with a united labor-management stance.
FY2024 saw us conduct these Diagnostic Checks onsite. With the use of a Responsible Care Progress Confirmation Chart did we prioritize the checking of progress on Responsible Care Activities, the unearthing of potential risks based on root-cause investigations of past accident cases with a view to taking recurrence prevention measures, and the extent of risk management in the production process.
The future will see us continue to value labor-management conversations as we seek to prepare a workplace environment in which employees healthy in mind and body can work while feeling at ease.

Education and Training

In line with the law and our Annual Responsible Care Plan, we deliver Safety and Health education tailored to employee jobs and job levels. Such education is focused on new hires and newly transferred employees at each business site. Among the vast range of programs we offer are: induction education at the time of transfer, pre-work-commencement safety education to transferred employees, safety education for new managers, education for foremen and supervisors at every plant, education on chemical substance risk management and the handling of such chemicals, and even education on the basics of the relevant science and laws.
Our delivery methods constitute an efficient and effective mix of online (E-learning and external lectures) and offline formats (group sessions and on-the-job training) aimed at raising safety and health consciousness among employees.

Initiatives: Health Management

Physical Health

Every Nippon Kayaku Group employee must undergo that most basic form of health management known as the “Periodical Health Check”. An occupational health physician will then decide on the employees in need of a health interview, and provide advice and instructions on health management.
We also lay on special health checks for employees who handle designated chemicals. The toxicity data on the chemicals they handle has been input into a database which forms the kernel of our risk assessments designed to prevent accidents and health hazards. Another initiative sees us promote THPs* for “building a healthy body and mind” at every business site in order to maintain and improve employee health. By reassessing the individual lifestyle habits of employees and promoting continual and systematic commitment to health, we are aiming for a situation in which everyone can live more healthily. Physical strength tests, health management competitions, group walks and hiking are also part of our health agenda.

Mental Health

If improved work productivity is to be compatible with successful creation of added value, then a workplace which allows employees to work energetically is just as indispensable as physical and mental health.
2005 saw Nippon Kayaku’s then-president release the Declaration on the Introduction of a Mental Health Care System and give thorough instruction to company management. Of importance to mental health care is for every employee to continually gather proper knowledge and recognition of the issues at hand so that they may swiftly detect mentally-suffering colleagues and work on preventative measures. At that point was emphasis placed on the initiative of “thinking of ways to prevent mental suffering as a top priority.”
Enlisting the help of guest lecturers from the EAP*, we commenced our Mental Health Training in FY2005, and in FY2006 devised a 3-year plan which made such training available to every employee. We have also set up e-learning initiatives to ease access to the training for the hearing impaired and for salespersons or other employee groups who are difficult to gather in a single place. For those obliged to take time off work due to mental health issues, we have set up a Return-to-Work Program. Links are forged between the employee’s supervisor, an occupational health physician and a counselor as part of a smooth Return-to-Work Support System that places priority on relapse prevention. 2 In line with revisions to Occupational Health and Safety Law, we began conducting stress checks on an annual basis in FY2015, with an employee take-up rate of over 97% in every year since. (Indeed, the take-up rate for FY2024 reached 96.6%). Stress check results not only allow us to ascertain an individual’s stress situation, but to analyze each organization, grasp high-stress workplaces and take follow-up actions.

Support for Workplaces without a Statutory Occupational Health Physician

Originally, with respect to offices not required to appoint an occupational health physician*, Nippon Kayaku was regrettably unable to set up occupational health physician interviews post-statutory health check or post-Nippon Kayaku Health Insurance Association Adult Disease Health Check. However, FY2013 saw us review this situation and dispatch our head office occupational health physician to the business sites in question to conduct the relevant interviews.
Since FY2014, this physician has toured every Nippon Kayaku office in the country. In addition to fixing an annual schedule for onsite visits, we also make use of a web meeting system to conduct further health interviews online.

  • *Offices not required to appoint an occupational health physician: Under Article 13 of the Occupational Safety and Health Law, and Article 5 of the Occupational Health and Safety Enforcement Ordinance, offices with fewer than 50 employees have no need to appoint an occupational health physician.

Health Management Competition

Since FY2018, Nippon Kayaku and a section of its Group companies have been working on health improvement initiatives by holding a companywide health management competition. A total of 2603 employees from across the Group got involved in FY2024, making for a participation rate of 74.2%.
The Companywide Health Management Competition is held in the March of each year. Every employee must log their health activities over the period of one month and convert them into points. The scores for each business site and Group company are then compiled by the Environmental Safety Division, before being aggregated and analyzed by the Environmental Protection & Safety Division. Among the various matters to be logged are: morning and lunchtime exercise, daily diet, brushing of teeth, sleep, number of paces walked, leisure and sports activities. Employees can choose to participate individually or in a team.
We will keep going with Companywide Health Management Competitions in order to help employees maintain and improve their health.

External Evaluations

Nippon Kayaku has been evaluated by the Ministry of Economy, Trade and Industry and the Nippon Kenko Kaigi Organization as “an enterprise that thinks about employee health management from a managerial perspective and tackles the issue strategically.” We have therefore been approved as a 2025 Health and Productivity Enterprise in the Large-scale Enterprise Category.*
This is testament to our vast number of initiatives on maintaining and improving employee health, including preserving a 100% take-up rate of periodical health checks, the introduction of stress checks and our mental health training. We also owe the award to our series of policies including: the extraction of health improvement issues to be tackled, coming up with relevant initiatives to improve health check results, introducing passive smoking measures, and setting up health-themed events for all employees.
Nippon Kayaku views employee health improvement as essential to increasing corporate prosperity and stakeholder satisfaction, and will therefore continue proactively engaging in health management activities.
