Stance and target

Why is "Occupational Health and Safety" a critical issue to be addressed?
Explanation of the reason and background

We believe that workers being able to work in a secure and safe manner serves as the foundation for operations. In terms of work-related accidents at the Yokohama Rubber Group in Japan and overseas, while the frequency of occurrence is low when compared with the average occurrence frequency for the production and manufacturing industry as a whole, it is not zero. Analysis of the causes of such accidents has revealed that many were prevented by countermeasures taken in advance. Because it is necessary to handle large-scale machinery at production plants due to the nature of our business, this leads to the possibility of major accidents from defects in equipment specifications and mishandling, and for this reason safety countermeasures are necessary. In addition, due to factors such as the fact that mental health issues account for an increasing percentage of long-term absentees, we need to respond fully to not only physical health, but mental health as well. For this reason, at the Yokohama Rubber Group we have selected occupational safety and health as a critical issue to be addressed.

Supporting System of Safety and Health Management

In Japan, we formed the "Safety and Health Sub-Committee" per division and workplace and the "Office-Wide Safety and Health Committee (legally stipulated)" per office under our Central Committee of Safety and Health that is headed by the CSR Department Manager. Activities on safety and health are an important approach common in companies and unions. Through interaction with the Japan Rubber Manufactures Association and Japan Rubber Workers Union Confederation to share safety information with other companies and other union confederation members, we are also trying to facilitate those by labor and management sides getting together. We also share our activities with our subcontractors by having them join their respective committees. As for our various overseas offices, they have their own supporting system in place according to the prevailing law under their country’s governance. Safety and Health Management Department manages activities on safety and health in both Japan and overseas.

Our Supporting System of Safety and Health Management

Vision (attainment goal) / target

  • We will promote the creation of a safe and comfortable working environment and good health.
  • We will establish a safety culture aiming for zero risks and aim for zero work-related accidents.

Measures for vision achievement

We will implement the following six measures to create workplaces that enable employees to work in a safe and healthy manner.

  1. Establishment of foundations for health and safety
    Enhance the check function through the continuation and improvement of the safety and health management system, the development of a hierarchical education system, and safety patrols, safety diagnosis, and diagnosis follow-ups.
  2. Strengthen safety measures for equipment and work
    Implement risk assessments for all equipment and work.
  3. Developing human resources that are aware of safety
    Conduct One-on-One education, develop safe workers.
    Reinforcement of Stop-Call-Wait procedure and countermeasures in response to causes.
    Implementation of KYT (Kiken Yochi Training/Hazard Prediction Training), sampling and improvement of near-miss incidents, and Hazard Demonstration Training.
  4. Creation of comfortable workplaces
    Chemical substances risk assessment, improvements in equipment development and working methods, thoroughly enforcing the 5Ss.
  5. Promoting both physical and mental health
    Strengthen mental health countermeasures (assessment of working hours, face-to-face guidance and work improvement suggestions for employees working long hours).
  6. Prevention of traffic accidents
    Conduct accident prevention activities and identify risk points on commuting routes in order to achieve zero accidents resulting in injury or death.

Review of FY 2014 activities

The following results were achieved for the measures implemented in FY 2014.

1. Establishment of foundations for health and safety
Occupational Safety and Health Management System (JISHA/OSHMS) certification has been acquired by 15 business locations in Japan and overseas, and certification was renewed for 5 Establishments during FY 2014.
In addition, the Mie Plant received its first OSHMS level-up audit by Japan Industrial Safety & Health Association (hereinafter, "JISHA") in accordance with JISHA standards in April 2015, and certification was renewed successfully.

2. Strengthening of safety measures for equipment and work
We implemented Risk Assessmet and Working Procedure Demonstraion in a planned and ongoing manner, and worked to discover risks and make improvements while developing standard prraion procedure manuals.

Risk Assessment

Working Procedure Demonstraion

While the frequency of occupational accidents was an improvement from FY 2013 at 0.08, we will continue working in an aim for zero.

Frequency of Occupational Accidents (Lost-time injury frequency rate)

Explanation of the numbers

* Lost-time injury frequency rate = (number of work-related injuries / total working hours) x 1,000,000 hours
* All data are annual aggregated value (January to December)
* All production industry (excluding general contracting) and manufacturing industry figures based on the statistic table Survey on Industrial Accidents released by the Ministry of Health, Labor and Welfare

  2012 2013 2014
Lost-time injury frequency rate 0.44 0.59 0.08
YRC frequency rate 0.81 1.25 0.86

The Group conducts strict management based on Yokohama Rubber’s unique frequency rates (all frequency rates).
Yokohama Rubber’s unique management standards (YRC frequency rate): The YRC frequency rate covers all accidents that occur at the company, and it is calculated including dispatched and contracted workers based on a coefficient of 1.0 for major or Lost-time injury resulting in leave (one day or more), 0.3 for minor injury not resulting in leave, and 0.1 for light injuries.
This is because we believe that it is necessary to enact countermeasures and work to prevent recurrence of not only injuries resulting in leave but all injuries including injuries not resulting in leave and light injuries involving everyone working at Yokohama Rubber in order to achieve zero accidents.

3. Further Enlightenment for Safety
We are trying to train our workers for good sensibility; who can foresee risks in any potential incident. We are conducting KYT (Kiken Yochi Training/Hazard Prediction Training) which is to be done by every worker every day, along with sampling and improvement for Hiyari Hatto (a near-miss accident) incidents that are voluntary activities to be attended by everybody. We have also conducted hazard demonstration trainings at Taikan Dojo (training through actual experience for accident prevention). Also, we have facilitated enlightenment on safety by focusing on communication like supervisor interacting with a worker one-by-one whilst understanding the meaning of each operation until they can have autonomy to conduct safe operations on their own.

  • Hands-on safety drills with overseas trainees

4. Creating Comfortable Workplaces
We have been proceeding with facility maintenance, improvement on work method, maintenance management in order to maintain comfortable work sites by conducting measurement of the work environment. Also, using 5S as a basis (Seiri [tidiness], Seiton [being organized], Seisou [cleanliness], Seiketsu [hygiene], and Shitsuke [discipline]), we are trying to facilitate efficient manufacturing such as required products that are safe when needed, and at required quantity only.

5. Promoting both physical and mental health
The Health Promotion Committee (labor-management framework for overall health activities) has created a system to thoroughly cover health activities through means such as the establishment of the Mental Health Subcommittee and Health Development Subcommittee in response to individual health activity issues as described below.
For the reinstatement of long-term absentees absent due to mental health reasons, we hold interviews with the employee involved, and confirm the situation with family physicians, industrial physicians, public health nurses, and the workplace in order to discuss matters such as the means of reinstatement, timing, and work limitations in order to achieve a well-planned reinstatement. Reinstatement has been achieved at the Head Office and Hiratsuka in cooperation with the Jikei University School of Medicine and three industrial mental health physicians, which is still a relatively rare position.
Furthermore, after reinstatement, regular three-party interviews are held between employees, industrial physicians, and workplace representatives in order to gradually loosen work limitations and provide follow-up until all restrictions have been fully released.

6. Preventing traffic accidents
Each business locations conducts awareness raising activities while cooperating with the holding of traffic safety seminars with local police stations and traffic safety related organizations. In addition, traffic etiquette classes are provided by traffic safety experts for students in the fourth grade of elementary schools located near our business locations to contribute to the prevention of local traffic accidents.

Iintroduction of initiatives

Suzhou OSHMS Exchange Meeting

The first Chinese OSHMS Exchange Meeting led by JISHA was held at Yokohama Rubber’s Suzhou Plant in November 2014. This exchange meeting was aimed at learning initiatives that could improve the effectiveness of effort to eliminate work-related accidents that are becoming a social problem in China. There was an active exchange of opinions with the participation of representatives from the Chinese government including the Vice Director of the Suzhou Administration of Work Safety, plant managers of local Japanese companies in China such as Yokohama Rubber, and JICA members providing safety and health technology assistance in China.

China-Japan Safety and Health Symposium
Yokohama Rubber participated in the China-Japan Safety and Health Symposium (Beijing) jointly held by the Japanese government (Ministry of Health, Labour and Welfare) and the Chinese government (State Administration of Work Safety) on February 5 to 6, 2015. The symposium was part of China-Japan occupational health technical cooperation efforts (five-year plan) that have been conducted since three years ago, which are aim to improve safety levels in both countries by having debates attended by specialists from both countries on the theme of safety and health issues that are common to China and Japan in order to share more specialized and concrete information and know-how. The Suzhou Yokohama Tire was the only private sector company representative to present a case study at the symposium.

Level-up audit

A Occupational Safety and Health Management System level-up audit was conducted in advance of other locations in Japan at the Mie Plant at the end of April 2015.

Issues and future improvement measures

There are still scattered chronic issues at older facilities, etc., and we are constantly committed to addressing these issues. In addition, we will strengthen initiatives addressing mental health, which has become increasingly important in recent years.
