Occupational Health and Safety

Creating Secure and Safe Workplaces

Occupational injuries

The Work-related Significant Occupational Injury (WSOI) frequency rate for the Mitsui Chemicals Group for fiscal 2016 was 0.23. On this basis, while we were unable to achieve the highest global standard for safety of 0.15 or below, this rate marks an improvement compared with last year. By type, half of all severe accidents occurring throughout the Mitsui Chemicals Group involved employees being caught or entangled in machinery. The frequency rate of Work-related Significant Occupational Injuries (WSOI) for domestic affiliates increased for the third straight year. In fiscal 2017, we will work to eradicate occupational injuries by setting goal for more thorough adherence to fundamentals at affiliates.
To address the frequent occurrences of occupational injuries caused by falling, we are promoting preventive measures based on proactively expanding the Ministry of Health, Labour and Welfare’s “Stop! Fall Injury Prevention Project.”

Frequency of DAFWCs (All industries/chemical industry / Mitsui Chemicals employees)

Frequency rate indicates the frequency of occupational accidents based on the number of individuals killed or injured by occupational accidents per 1 million hours of total working time.
Average DAFWC rate for all industries in Japan and for the chemical industry. Mitsui Chemicals aggregate data for DAFWC rates up to the second half of fiscal 2012 and work-related significant occupational injuries from the second half of fiscal 2012 onward.

Instruction in Hazard Prediction (Kiken Yochi, or “KY”) as well as Pointing and Calling

At the Safety & Environment Technology Division, we have been supporting occupational safety-related efforts to eliminate occupational accidents at domestic and overseas affiliates since fiscal 2006.
In particular, we have been continuously holding KY (kiken yochi: hazard prediction) and pointing and calling training, conducting such training 40 times in Japan for 852 individuals participating and 14 times overseas for 272 individuals over the past three years. There has been an increased understanding of the significance and necessity of KY activities among all affiliated companies, and we are currently focusing on training that entrenches KY activities. To this end, our training approach incorporates drills, presentations, and team discussions based on practical operations while keeping lectures to a minimum. We will develop key persons able to play a pivotal role in providing hazard prediction training at each affiliated company.

In addition, we toured the outstanding workplaces recognized by the President’s Award for Best Plant as well as held an exchange meeting as a means to exchange information. Starting in fiscal 2015, this year marks the second time we have held this event with the aim of enabling employees to be aware of and take action to improve deficiencies in their workplaces and Works, provide opportunities for line managers to share their concerns and encourage each other, and improve the safety culture throughout the Mitsui Chemicals Group.
Held over two days on February 9-10, 2017, this year’s exchange meeting was held at the Omuta Works, with a total of nine line managers participating from the Fine Chemicals Section at Omuta Works (recipient of the fiscal 2015 President’s Award for Best Plant) and other Works as well as affiliates in Thailand (SMPC and TMSC). We received positive feedback from participants. This included such comments as “Line managers consider what they can do to help eliminate the burden on operators and are implementing thoughtful measures. This is helpful for me as a reference for my own activities.”

Plant Operation Technology Training Center Open for External Use

Fiscal 2016 marks a decade since Mitsui Chemicals opened the doors of its research facility, Mitsui Chemicals Plant Operation Technology Training Center (located at Mobara Branch Factory) in October 2006 to train manufacturing operation personnel with the aim of enhancing the Company’s production workplace capabilities. During this period, the center has expanded its curriculum and number of employees eligible for training along with taking steps to improve its training programs. Establishing a similar training center at an overseas production site, the center engages in the Group-wide training of employees to excel at all aspects of safety, operations, and equipment handling while being able to solve problems on their own. Starting in fiscal 2015, the center has accepted individuals from companies outside of the Group to participate in experience-based training conducted internally to date. Consequently, the Center has received a large number of visitors so far (fiscal 2015: 462; fiscal 2016: 390), with around 360 trainee applications received in fiscal 2017.
Leveraging past cases of various types of accidents and problems experienced within the Company, Mitsui Chemicals will continue to actively provide experience-based, safety-focused training curriculums to companies and individuals outside the Mitsui Chemicals Group as a means to contribute to the development of human resources for production worksites throughout the industrial world.
