Occupational Health and Safety

Locations covered: Hachioji Plant and Tsuchiura Plant

By accident type, “flying or falling objects” and “cuts or abrasions” accounted for the majority of accidents. In response, we are continuing our efforts to prevent recurrence and raise safety awareness through education and guidance on equipment handling, thorough implementation of protective equipment wear, and thorough implementation of the 5S*.

Locations covered: Hachioji Plant and Tsuchiura Plant

At the Hachioji and Tsuchiura plants, we have established the Safety and Health Committee, with each plant manager serving as the general safety and health manager. The committee plans and deliberates on major health- and safety-related matters in a bid to maintain and improve a safe and comfortable work environment. To raise employees’ awareness of health and safety in the workplace and in the interest of maintaining and promoting their health, the committee meets once a month, in principle, and on an ad hoc basis when the general safety and health manager deems necessary. In fiscal 2022, the committee met 12 times, as scheduled.

We also conduct internal audits twice a year, with results submitted to the Audit Department and reported to the Board of Directors. The Health and Safety Committee is subject to audits by the Audit Department.

We provide in-house training to help employees avoid hazards in a variety of situations, including commuting, traveling, and working in the factory.

Each year, each plant’s Disaster Prevention Subcommittee plans and conducts emergency evacuation drills for all departments in the plant. The Hachioji Plant conducted an evacuation drill in fiscal 2022 under the e-learning theme "Cardiopulmonary Resuscitation and AED Use Procedures." The details of such training are reported to the Tokyo Fire Department, by submitting a “Notice of Self-Defense Fire Drill Implementation.” 

Emergency scenario training is conducted at least once a year at each plant so that appropriate tasks, such as recovery/cleaning, can be carried out in the event of a hazardous substance leak or splash-based accident. Each division that handles hazardous substances submits a training plan to the person responsible for environmental management at the beginning of the relevant term and submits a report after the training is conducted. In fiscal 2022, the Hachioji Plant conducted training 32 times for 11 divisions. At the Tsuchiura Plant, 143 people from the plant department took part in chemical cleaning agent splash prevention training.

In order to promote activities to prevent industrial accidents among local workers, we participate in seminars held by the Hachioji Branch of Tokyo Federation of Labour Standards Associations. These seminars are designed for participants to acquire the skills necessary to engage in work. Employees who have completed the seminars take in-house practical tests tailored to factory environments for thorough health and safety education.

The Semiconductor Equipment Association of Japan promotes SEAJ recommended safety training an industrial standard for safety training of personnel involved in the installation,
maintenance, and servicing of semiconductor manufacturing equipment. At the Hachioji Plant, our employees who belong to Semiconductor Equipment Association of Japan’s Safety Training Subcommittee conduct online-based SEAJ Work Safety Seminars for Semiconductor Company CE Department employees and manufacturing and design engineers who work on the manufacturing floor or in clean rooms. A total of 430 employees have participated in the seminar so far.

When considering the purchase of industrial chemicals, we conduct a chemical substance risk assessment to check for the presence of contained environmental pollutants (organic
solvents, specified chemical substances, hazardous materials, etc.), in accordance with our internal regulations. The department in charge of this matter at the Hachioji Plant decides whether to purchase the chemicals based on the results of assessments conducted at the Hachioji and Tsuchiura Plants. In fiscal 2022, 76 new chemical substance risk assessments were conducted at the two plants, both for new uses and for reviews of existing uses.

We require divisions that manage and use chemical substances to conduct regular inspections and regular quantity checks. The Company is also promoting the reduction and substitution of chemical substances in accordance with the PRTR Act, Ordinance on Prevention of Organic Solvent Poisoning, and the Poisonous and Deleterious Substances Control Act. In addition, we carry out patrols to check the status of chemical management and storage and the supplies used to prevent chemical leaks through the Regulated Substance Control Working Group under the Safety and Health Committee.
