Introduction to Small-group Activities

Each Works at Mitsui Chemicals takes a bottom-up approach to plant operations through small-group activities. Typical examples of specific activities are as follows.

・ Omuta Works

On February 17, 2017, Omuta Works held a presentation on 5S activities. With 192 people participating, 10 teams gave spirited presentations on their respective activities.
The General Manager of Omuta Works summed up his review of the event by commenting: "Today’s outstanding event certainly provided memorable presentations, and it reaffirmed my belief that the Omuta Works is really running smoothly. With all of you picking topics based on the challenges you face, you conveyed very well your ingenuity as you moved forward.”

・ Iwakuni-Ohtake Works

On March 28, 2017, the Iwakuni-Ohtake Works held an event where 11 teams, selected by block screening from a total of 132 teams, gave presentations of small-group activities for fiscal 2016. With the goals of “human development” and “organizational development,” this marked the third year of the small-group activities that had been resumed from 2014. This event demonstrated that steady progress was being made. In fiscal 2017, we will establish the “Bamboo Shoot Activities Reinforcement Committee,” and as one important issue at the Works, we will continue activities while working toward further vitality.

Bamboo shoot activities:
A generic term used to refer to the Iwakuni-Ohtake Works’ small-group activities and improvement proposal activities.

・ Ichihara Works

On May 31, 2017, the Ichihara Works held presentations of its small-group activities. This event was a competition of 11 elite teams from each unit, namely, five from the Manufacturing Department, two from the Technical Department, three MCOS teams, and one team from the Mobara Branch Factory. The teams participating in this event were selected from among the 134 teams of the Ichihara Works, and 40 teams from the Mobara Branch Factory. They covered a diverse range of activity implementation topics, and at this event it was difficult to say which one stood out. At this Works site, the “transformation of organizational culture, realizing an active Ichihara Works” was raised as one topic, and measures being taken included “vitalizing small-group activities.” As a description of activities, it was outstanding to have items such as further brushing up improved activities from the problems faced close at hand.
In addition, from this event we newly established the “Works General Manager’s Special Award,” which recognizes quiet dedication, as we look forward to energized and further developed activities of the small groups.

・ MCOS (MC Operation Support)

On July 27, 2016, Ichihara Works held a presentation on MCOS companywide small-group activities. MCOS refers to MC Operation Support, a spin-off affiliated company that provides production support for Mitsui Chemicals, mainly overseeing disaster prevention security services, filling/packaging, and operations/operational support at key domestic production sites.
As the 10th anniversary celebration of the establishment of MCOS, this event was attended by the head of the Production & Technology Center from Mitsui Chemicals Inc., the Ichihara Works general manager, and other related parties, with 11 teams, including those from subcontractors, giving it their all. The head of the Production & Technology Center summed up event by stating, “I’ve had the honor of attending this MCOS companywide event every year since 2011, and I’ve always looked forward to hearing about your worksite initiatives. I’m very impressed with the presentations I heard today. Moving forward, to the employees of Mitsui Chemicals, and to all of you, I hope we can work as one to improve the way we do things, so I ask for you kind cooperation and support.” We expect these presentations to steadily underpin the foundations of each Works going forward.

Instruction of Hazard Prediction (kiken yochi, or “KY”) as well as Pointing and Calling

At Mitsui Chemicals, we undertake initiatives at all our factories with activities that entrench and energize hazard prediction (Kiken Yochi, or “KY”) and pointing and calling.
Pointing and calling is a technique whereby at designated areas, the status of operations is confirmed, leading to further improved execution rates, and other benefits. The aim of this technique is to raise the level of operations, with each of the Works sites establishing their respective annual plans, and putting the PDCA cycle into effect. Examples of the main activities in fiscal 2016 are introduced as follows.

  • Ichihara Works
    Implemented a workplace system that utilizes a “self-question card” and “one-person KY.” Establishing important points for pointing and calling, with all-employee participation
  • Nagoya Works
    Conducted KY brush-up training for those employees performing front-line operations
  • Osaka Works
    Held worksite KY leader meetings for horizontal development of best-practice activities
  • Iwakuni-Ohtake Works
    Conducted direct KY guidance through worksite visits, held KY training conducted by external trainers.
  • Omuta Works
    Guidance activities performed by KY trainers (confirmed items for horizontal development, attended A-rank construction meetings, safety patrols and other operations)

KY trainers are chosen at each Works to perform as drivers of these initiatives, and once per fiscal term, Companywide meetings are held. At these meetings, KY trainers report on the status of KY initiatives at their Works, and communications from the Head Office are presented. Sharing information enables KY trainers to reference the information with regard to KY activities at their own Works.

Introduction to Near-miss Activities

At each Mitsui Chemicals production site, information on workers’ narrowly avoided major accidents or disasters, or “near-misses,” that occur as a result of operations, is identified with details are shared within the organization. These sharing activities are ongoing.
In line with the occupational safety and health management system for each production site, the organization determines the cause of these near misses, as well as preventive measures. Those concerned are provided with the awareness gained, and plans are put into effect that cover both concrete matters, as well as more intangible issues, in the course of operations.
In carrying out these preventive measures, Mitsui Chemicals continues to secure necessary resources. Examples of specific representative measures are as follows.

Omuta Works
A monthly meeting, with full attendance, is held to discuss information on the near misses submitted by worksite employees (Company employees as well as subcontractor employees).
With regard to those items that section managers, chiefs, and foremen determine to require discussion, together with confirming such details, confirming worksite, and deliberating on measures, a list is created that can be shared with all employees, and progress management and reports on measures are provided.
Through these discussions, potential risks at one’s own worksite are detected quickly, and risks minimized.
