Promotion of Process safety and Disaster Prevention and Industrial Health and Safety

Under our corporate philosophy, "We will contribute to the safety, security, and prosperity of society by leveraging our unique scientific creativity to protect and foster life and nature." we aim to cultivate an open corporate culture by building a safe, comfortable workplace and promoting active communication. Our group primarily conducts chemical manufacturing as its main business, and due to the nature of this business, if a serious accident occurs it could harm not only our employees but also the contractors who cooperate with our operations and local residents. Accordingly, we recognize occupational health and safety, and process safety and disaster prevention as top-priority issues; therefore, we are carrying out various activities toward this end. We started company-wide operation of the Occupational Health and Safety Management System (OHSMS) in January 2026. We are also working toward obtaining ISO 45001 certification, the international standard for occupational health and safety, by October 2026, primarily at our factories. At each of our offices, in cooperation with the Site OHS Secretariat, the establishment identifies hazards related to work that affect contractors and the establishment, evaluates OHS risks, and manages them for contractors working on-site using the "Contractor Compliance Instructions Confirmation Form."

We hold a Responsible Care Promotion Committee, chaired by the President (Representative Director and President, Masaru Yokoyama) and headed by the officer in charge of Responsible Care (Director and Senior Managing Executive Officer, Takumi Yoshimura), with all full-time Executive Officers participating, to oversee matters related to occupational health and safety, process safety and disaster prevention, and the environment across the company and to make decisions regarding policy and the allocation of resources. In addition, the matters decided here will be carried out by the Responsible Care Promotion Section, and we are working to enhance occupational safety across the entire group by providing technical support and exchanging information not only within the company but also with group companies.

Please see Responsible Care Management for details.

Furthermore, to promote the OHSMS, we have established the following organizational structure and appointed the General Manager of the Sustainability Promotion Department as the overall OHS management officer.

At each office, the Safety and Health Committee meets monthly to discuss the safety, health, and wellness risks specific to that office. The Safety and Health Committee is organized so that representatives of the workers make up the majority of its members, and care is taken to ensure that workers' voices reliably reach management (or top management).
By having the main contractors participate in the meeting, we ensure effective discussions for everyone working in the office. The matters discussed here will be documented as meeting minutes and communicated to all employees.

In our production division, we fell short of the goal of "zero serious workplace accidents (requiring four or more days off work)," recording one case in FY2025. For comparison with industry standards, we compare our performance based on the frequency of occupational accidents (requiring one or more days off work) compiled by the Japan Chemical Industry Association, a general incorporated association of which the chemical industry is a member. Our company’s lost-time injury frequency rate tends to be higher than the manufacturing industry average, and we analyze that this is due to our business structure, which carries out low-volume, high-mix production activities. We recognize this situation as an issue, and when a workplace accident occurs, we use analysis tools such as 4M5E to address the root causes of the accident and work on recurrence prevention activities. In the event of a serious occupational accident or accident, the Secretariat of the Responsible Care Promotion Committee shall establish an Occupational Accident and Accident Response Working Group, implement measures aimed at the rapid resumption of operations, conduct environmental, health, and safety checks (risk assessments), and determine and approve whether operations may be resumed. In FY 2025, no major incidents affecting nearby residents have occurred, but if one were to occur, we have a system in place to disclose it on our corporate website.
In addition, we compile reports on the disaster occurrence status and areas for improvement and manage them accordingly. By sharing the reports with each business site through the internal groupware, we use them to help prevent similar disasters from recurring.
