In the MMC Group Code of Conduct, we vow to “We are committed to providing a safe and healthy environment for all our stakeholders.” This is based on the notion that, if we can’t keep our employees safe and healthy, they won’t be able to provide secure and happy lives for their families, we won’t be able to operate effectively, and we will never be able to keep on expanding as a company.
And since 2018, we have declared that among the goals represented by SCQDE enacted as the guideline to decision-making concerning conduct of our work (priority order), “S” which represents “Safety and Health” is the first priority.
| 1 | ＳSafety & Health | Safety & Health come first |
|---|---|---|
| 2 | CCompliance & Environment | Compliance & Environment to ensure fair activities |
| 3 | QQuality | Quality of products and services provided to our "customers" |
| 4 | DDelivery | Delivery dates to be met |
| 5 | EEarnings | Reasonable profit (Obtained based on “customer” trust after satisfying SCQD) |
“SCQDE” shows the order of priority of our business decisions. In providing customers with our products & services, we should thoroughly fulfill SCQ at first and satisfy D. We believe that we will be able to obtain trust from customers and society by continuously executing SCQD in good faith, and this will produce a reasonable profit.
In the wake of the fire and explosion at our Yokkaichi Plant in January 2014, we launched a new Zero Occupational Accident Project in April that same year, and set about strengthening the foundations of safety and health on a groupwide scale, with the aim of eliminating serious occupational accidents resulting in four or more lost days (not causing any occupational accident resulting in four or more lost days for one year).
The Zero Occupational Accident Project is led by the Zero Occupational Accident Subcommittee, which serves as a special subcommittee under the Sustainable Management Office headed by the Chief Executive Officer.
Based on factors including occupational accidents that have occurred, the Zero Occupational Accident Subcommittee, which consists of Safety Coordinators from the departments, identifies priority issues that our Group should tackle, sets priority tasks for safety and health management through exchanges of opinions with the Zero Accident Labor-Management Meeting, which consists of management and labor union members, and strives to make improvements through the PDCA cycle in accordance with the situations of each facility.
Specific measures for the Zero Occupational Accident Project are implemented after deliberations and approval at the Strategic Management Committee and their progress is regularly reported to the Sustainable Management Office.
Implementation of each measure revolves around the Mitsubishi Materials Safety, Environment & Quality Department. With Safety Coordinators appointed at each in-house company, we share information regarding progress and issues with safety and health measures at business sites under their management, including Group companies, and discuss solutions to the issues at monthly meetings with the Safety, Environment & Quality Department.
We have an integrated groupwide promotion framework in place whereby matters that extend beyond the confines of individual companies are reported and discussed at the above-mentioned Zero Occupational Accident Subcommittee.
At the same time, the occupational safety and health management systems are operated at individual business sites. In addition, Safety Managers, Safety Coordinators and Safety Instructors are assigned to individual business sites, where their role is to promote safety activities. We hold regular Groupwide Safety Manager meetings and meetings for Safety Coordinators and Safety Instructors, where we exchange openings on a wide range of occupational accident information and health and safety activities across the Group and the various business sectors in which it is involved, and endeavor to raise the level of health and safety.
To expand the joint labor-management initiative to achieve zero occupational accidents, we have identified issues at the MMC Group in light of occupational accidents, etc. that occurred last year, engaged in joint labor-management discussions on the particular items to be addressed to achieve solutions, and designated management priorities on that basis. In 2021, we set out the following management priorities, and rolled out occupational safety and health management systems at each of our plants/factories accordingly.
While the number of serious occupational accidents related to machines and electricity and those related to handled materials caused by equipment has been decreasing in the long term, there remains residual risk that we have yet to reduce, and not a few accidents have occurred due to unrecognized hazard sources. In response, we decided to examine the appropriateness of risk assessments that we have conducted to date, over a period of three years from FY2021, in our attempt to review requirements. We take the following actions.
An analysis of the types of occupational accidents occurring at the MMC Group has revealed that many occupational accidents occur due to two factors: “flawed protective and safety measures” such as incomplete safety measures for machinery and equipment, and “proximity to dangerous areas,” such as touching machinery or equipment while it is operating. To strengthen the physical measures in place by reviewing structures and mechanisms from the perspectives of the foolproof*¹ and failsafe*², we are employing thorough engineering-based action through risk assessments.
Further, with respect to occupational accidents caused by “flawed operating methods” such as the use of inappropriate tools and jigs or incorrect operating procedures, we will strive to make risk assessment-based improvements including the verification of operating methods, and revised operating procedures that reflect hazard prediction. Risk assessment is an effective means of discovering, eliminating or mitigating potential danger or harm attributable to operating practices and other work performed at a manufacturing site. At the MMC Group, we implement risk assessment activities from the perspective of workers on the production floor at each business sites. We have trained risk assessment instructors at each business site to improve their ability to identify unsafe equipment states and began offering training classes in October 2015. As of March 2020, more than 520 people have taken the course (although classes could not be held from April 2020 onward due to the impact of COVID-19). Centering on these instructors, the course is contributing to enhancing and stimulating on-site activities. In addition, since August 2020, we have been conducting risk assessment classes by remote learning, led primarily by front line supervisors with the aim of raising the ability level of personnel who conduct risk assessments. As of March 2022, 419 people have received training in those classes.
The number of employees involved in occupational accidents (injuries without lost time) in the Company and at 20 major Group companies stood at 164 in 2021. Sadly, 40 of these were accidents requiring employees to take leave. 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 number of business sites increased by two as a result of the merger of the former Mitsubishi Shindoh Co., Ltd. in April 2020.) The accident frequency rate which evaluates the state of occurrence of occupational accidents taking place at the Company (LTIFR (Lost-Time Injury Frequency Rate): casualties per million actual hours worked (employees taking time off work)) was 0.21; a lower figure than the 2021 manufacturing business average of 1.31 (Ministry of Health, Labour and Welfare (MHLW) statistical data). The accident frequency rate including accidents not requiring employees to take leave (TRIFR (Total Recordable Injury Frequency Rate): casualties per million actual hours worked including accidents not requiring employees to take leave) was 1.68.
In 2022, too, we worked thoroughly to further increase the safety of facilities through risk assessments, added further measures to prevent accidents, and made other efforts toward achieving our zero accident target.

In 2021, there were 16 accidents (fires and explosions, etc.) at the Company. They include two cases of fire, where it took a certain amount of time before the accident ended. However, all of the other 14 accidents were minor ones scoring 3 points or less (with 13 of them scoring 1 point or less) under our internal accident evaluation standards, which are a measure of the magnitude of damage and impact. There was no explosion in 2021. There were zero (0) Tier 1 process safety events (PSEs) per million hours. The Company bases its definition of PSEs on the CCPS definition. ※
However, partly because the total number of accidents was much higher than in the previous year (seven), we will continue to pursue initiatives that focus on fire prevention through the internal proliferation of accident data, among other measures.
