Occupational Health and Safety, Process Safety and Disaster Prevention

Occupational Health and Safety

With the goal of achieving zero occupational injuries, we regularly conduct safety-related education and drills and occupational health and safety risk assessments. In addition, each workplace continuously engages in everyday safety tasks such as 5S activities, hazard prediction, and proposals for addressing Hiyari Hatto (near-miss) incidents.

We share information on occupational injuries, perform risk assessments, provide safety education, and carry out joint disaster mitigation training to prevent industrial accidents at partner companies, while working to enhance our cooperative frameworks.

Process Safety and Accident Prevention

To prevent the occurrence of accidents and injuries, it is important to continue stable operations by ensuring the safety of production processes and the soundness of equipment. At each plant, we utilize equipment maintenance system (M3) and other systems to conduct checks and make renewal plans, and perform checks, repairs, and renewals with priority set according to risk and the importance of facilities.
We are also using case studies of past accidents to verify the effectiveness of countermeasures and engaging in initiatives aimed at preventing the occurrence of similar accidents. We carry out facility risk assessments that simulate non-steady-state operations, such as emergency shutdowns.
Furthermore, in addition to converting standards manuals to “Know Why,” we are also introducing operation simulation training.

Responding to emergencies

In preparation for accidents, we establish a self-disaster readiness framework at each business site and carry out various disaster reduction drills according to sites’ annual plans.

Certified high pressure gas plants

The Niigata Plant and Mizushima Plant, which are high pressure gas safety management code certified plants, are audited by the Director in charge of environment and safety (Process Safety Management General Controller) under the company rules for “High pressure gas certification safety management”. The aim of our audits is to objectively evaluate the high pressure gas safety management system and the certified inspection management framework to ensure that they are working effectively.
