Process Safety and Disaster Prevention

Based on our management policy of putting safety first in everything that we do, we have continued to implement a range of safety activities throughout the Mitsui Chemicals Group. Reflecting deeply on the explosion and fire that occurred at our Iwakuni-Ohtake Works in 2012, we have since implemented a series of preventive measures as well as fundamental safety measures to ensure that nothing like this ever happens again, anywhere within the Mitsui Chemicals Group.
With the utmost sincerity, we have made a firm commitment to promoting safety on the understanding that safety is essential and for the benefit, not only of ourselves, but also our families, colleagues, and society as a whole. Taking this commitment very much to heart, we are thinking carefully about what we can do to ensure safety and taking all appropriate actions. As a part of our Safety Day and other activities, each and every member of the Mitsui Chemicals Group repeatedly recites this pledge to ensure safety is our top priority.
