We thought that personal experiences of hazards are important to improve hazard awareness, so started running an Occupational Safety and Health Education Center -“Midori-kan” in March 2017. The center has 50 different hazard experience facilities inspired by the actual work environment and the dangers that hide in everyday tasks. It also regularly provides specialized education needed for work safety and health in dedicated classrooms, in addition to hazard experience education by expert instructors. Since its establishment until March 2020, the center provided hazard sensitivity training for more than 3,800 Group employees, approximately 650 of whom have also complete specialized training courses.

Hazard experience education using VR (virtual reality)

We introduced VR hazard experience education at our Occupational Safety and Health Education Center in May 2018 to allow participants to experience hazard difficult to simulate with regular equipment. VR allows participants to have a 360° field of vision, better realism and immersion through haptic and other technologies, and experiences of hazard until the end (e.g., before, during and after falling). It is helpful for creating better hazard awareness. Because the devices are portable, we provide the training at each plant of the Group. In 2019, we introduced second and third sets of devices and added five new hazard experience courses. We began to lend them to Group companies as well, aiming to improve hazard awareness further.

Strengthening Safety and Health Systems

Establishing a Safety and Health Award Scheme

We have established a scheme to award groups and individuals serving as an example to the MMC Group in outstanding safety and health improvement activities over the course of the year.
As the activities carried out by grand prize winners cannot be adequately described in writing, we hold guided visits of facilities open to groupwide participation as an opportunity to observe the award-winning activities as well as exchange opinions and gain insight into overall safety and health improvement activities. The fifth awards were presented in April 2020. The below table lists the facilities presented with awards in the group category. Moving forward, we will continue to actively roll out these outstanding activities within the Group in a bid to further raise the levels of safety and health.

Safety and Health Instruction Utilizing Outside Consultants

As the results of an analysis of past occupational accidents revealed issues in risk identification, we have been providing MMC Group facilities with safety and health guidance through outside consultants. Having an expert point out latent risks that are usually overlooked by on-site personnel and taking measures to mitigate the identified risks raises the on-site safety level and improves the hazard sensitivity of employees.

Promoting the Rollout of Information within the Group through Consolidation and Dissemination

The Safety & Environment Department has been running an internal portal website since February 2017 for the collection, dissemination, and viewing of information about safety, health, disaster prevention and the environment. As regards health and safety, safety data and safety chronology that had previously only been stored on head office servers along with occupational accident case studies, documents used for safety and health training and information concerning health and mental health have been classified, organized and published to the intranet.
Computer graphics have been used to produce videos depicting cases of typical occupational accidents that have occurred in the MMC Group. The videos can be used to offer straightforward explanations of the conditions of an occupational accident, its cause, countermeasures taken and the lessons learned.
All past accidents in the Group have been entered into a database. That database has been available on the internal portal website since June 2017. It allows keyword and full-text searches and the creation of accident calendars, contributing to the preparation of safety education materials as well as measures against similar accidents. It is constructed so that all plants can obtain the necessary information swiftly and accurately, helping to bolster our safety foundation and foster a safety culture.

Disseminating Examples of Safety and Health Best Practices

Since 2014, we have been compiling a collection of safety and health best practices on a yearly basis, highlighting unique and highly-effective initiatives implemented at each MMC Group facility to prevent occupational incidents. We are promoting the spread of best practices by presenting them during National Safety Week as a shared asset for increasing the Group’s safety and health levels.

Safety Record

The number of employees involved in occupational accidents, including injuries without lost time, in the Company and in 22 major Group companies was 185 in 2019. Of these, 32 were lost time injuries. The number of accidents at the Company, on a non-consolidated basis, has been showing a downward trend for the past ten years, but it has leveled off in recent years. The Company’s accident frequency rate (number of deaths and injuries per 1 million working hours), which is an assessment of the frequency of occupational accidents, was 0.17. This is lower than the manufacturing industry average of 1.20. In 2020, we will further ensure equipment safety through risk assessment, add further measures for preventing accidents, and promote initiatives to achieve our goal of zero accidents.
