Mitsubishi Chemical Corporation: Thanks to stronger coordination with business partners, large-scale periodic maintenance work at our chemical plants was completed with zero accidents

At Mitsubishi Chemical Corporation's Mizushima Plant, large-scale regular maintenance of continuously operating facilities including the ethylene plant, which is conducted once every four years, was carried out in fiscal 2013. With the aim of achieving zero accidents during maintenance work, we discussed the various themes, work procedures, rules, the 3S (Sort, Set in order, Shine), and information sharing with business partners during the nine months before the start of work, thereby establishing a task framework. As a result, we achieved zero accidents and injuries.
