Safety and health measures

Based on the recognition that ensuring the safety and health of employees and subcontractors is the foundation of our corporate activities, we obtained certification for OSHMS (Occupational Safety and Health Management System) conforming to the JISHA (Japan Industrial Safety and Health Association) method in December 2011 as a means of achieving a safe, healthy, and comfortable workplace. Since then, we have continued the certification.
We also plan to transition to ISO45001 by 2026.
We have been developing the following activities based on the four pillars (one-to-one dialogue, near-misses, hazard prediction, and risk assessment), which are centered on interactive communication between the work system and workers.

• Sharing of issues through the Health and Safety Committee (once a month)
• Environmental and safety subcommittee meetings for subcontractors, safety patrols by subcontractors and the facilities section, labor-management council meetings, and meetings of safety managers (once a month for each).
• Regular safety follow-up by factory top management
• Strengthen management of overwork
• Preventing accidents that have occurred in the past from fading out

Education and training for employees

Safety education for employees begins with safety and health education at the time of employment, followed by one-on-one dialogues with employees by role holders, sensory training, risk assessment practical training sessions, and safety person certification and development training.

Responses in case of disaster

In response to disasters, regular disaster drills are conducted in accordance with the annual activity plan for fire and disaster prevention. During drills, a self-defense firefighting organization headquarters is set up and firefighting and rescue drills are conducted to ensure a comprehensive response. We also engage in earthquake disaster drills, BCP drills, and nighttime evacuation drills, assuming various patterns.
We also regularly conduct first aid and CPR training sessions to promote life-saving skills.

Reductions in greenhouse gas emissions

1. Active introduction of environmentally friendly high-efficiency products

In accordance with our mid- to long-term energy conservation plan, we are replacing transformers, fans/pumps, and lighting fixtures with LED fixtures and air conditioning equipment with high-efficiency equipment.
We have implemented the following energy-saving measures: 15 motor inverter conversions, 7 step-down transformer replacements, 3 pump replacements, 1 dehumidifier replacement, 4 air conditioner Mi-coil installations, and insulation material upgrades.
Additionally, the Hf fluorescent light fixtures were updated to 784 LED base lights.
We installed a 1,750 kW rated solar panel array on the roof of the DC warehouse at the Minami Plant and began construction in fiscal year 2024, with power generation scheduled to start in April 2025.
In order to drastically reduce GHG emissions, we converted the fuel at the Minami Plant to LNG in January 2025 and started operating high-efficiency boilers.
We expect to reduce CO2 emissions by more than 2,300 tons per year by converting to LNG.
We will continue to work on reducing GHG emissions throughout our plant.

2. Advancement of energy-saving activities

In addition to increasing the efficiency of the supply side, we are repairing leaks of steam, industrial water, and factory air on the consumption side, as well as augmenting heat insulation. 35 low-voltage operating transformers upgraded to higher efficiency in FY2023.
In monthly meetings of energy conservation subcommittees where all process managers gather, we strive to share problems and introduce individual initiatives in an effort to educate the public.

Reporting on chemical substance management status (Pollutant Release and Transfer Register (PRTR) Law compliance)

The Shinshiro Plant verifies whether secondary materials and auxiliary materials contain chemical substances subject to Safety Data Sheet (SDS) requirements, and in the case of substances where the amounts handled exceed the thresholds specified by the PRTR Law, annual reports are submitted to the national (or prefectural) authorities and safety impact assessment is performed.
Regarding the handling of substances pursuant to the PRTR Law, please refer to the Safety Evaluation Table of Domestic Production Bases.

In addition, as part of efforts to improve the level of chemical substance management, we conduct chemical substance risk assessments to identify risks of adverse effects on workers' health, explosions and ignition of facilities and equipment, and environmental risks, and confirm compliance with laws and regulations.

Biodiversity protection activities

Our plants use a lot of river water to produce tires. We have been asking ourselves, "Is it enough for us to just receive water resources from nature? What can we do about it? With this in mind, we started biodiversity conservation activities focusing on water in 2012, and next year will mark the 12th year since then.
As for activities in FY2022, the impact of the COVID-19 disaster has gradually faded, and the number of people involved in activities has increased.
We will continue to collaborate with the government, universities, NPOs, and other companies by interacting with the Yotsuya Senmaida Preservation Society, one of our activity sites, and participating in the Shinshiro Shitara Ecosystem Network Council promoted by Aichi Prefecture. Yokohama Rubber's Shinshiro Plant will continue to contribute to biodiversity in the Shinshiro Shitara area by providing and planting broadleaf trees and seedlings grown from local seeds through the Forever Forest activities.

Relationship with local societies

On June 19, 2024, we hosted a factory tour and discussion with 10 local district heads and environmental monitors. We value their feedback and will use it to further improve our factory operations and become an even more community-friendly facility.
54 employees participated in the Shinshiro Clean Festa (supported by Shinshiro City) in June 2024, contributing to local beautification efforts. Additionally, 420 employees regularly participate in cleaning activities around our factory.
