Safety and Prevention
Accidents and Occupational Injuries
The Mitsui Chemicals Group positions as KPIs and monitors major accidents, the number of abnormal conditions/accidents as well as the occupational injury frequency.
Major Accidents and Abnormal Conditions/Accidents
In fiscal 2018, the Mitsui Chemicals Group suffered one major accident*1, compared with a target of zero, the number of abnormal conditions/accidents*2 was 11, compared with a target of five. With regard to these abnormal conditions/accidents, we completed investigations into the causes and the horizontal deployment to all manufacturing sites. We are promoting preventive measures across the Group.
Accident with a severity level of 18 points or more, as specified by the Japan Petrochemical Industry Association (JPCA) under Center for Chemical Process Safety (CCPS) evaluation procedures.
Although under JPCA accident criteria having a severity level of less than 18 points, conditions/accidents that the Company judges should be monitored under Company standards taking into account the relevant laws and regulations.

*Scope of data compilation for domestic and overseas affiliates: Affiliated companies eligible for Responsible Care support
Compared with the Japanese overall industry average and the Japanese chemical industry average, the Company maintains a high level in terms of Days Away from Work Cases (DAFWCs) and, in aiming to achieve the world’s highest standards for safety, targets a frequency of 0.15 or below with regard to significant occupational injuries*.
The significant occupational injury frequency for the Mitsui Chemicals Group for fiscal 2018 was 0.33, and thus we were unable to achieve the targeted numerical value of the highest global standard for safety of less than 0.15. Breaking down that value, the significant occupational injury frequency for both domestic construction subcontractors and the in overseas affiliate companies worsened to 0.51 compared to the previous year. Having thoroughly checked the content of the breakdown, we will expand the scope of the data compilation in fiscal 2019. In contrast, there was a significant improvement in the significant occupational injury frequency for Mitsui Chemicals. In having conducting a simple risk assessment for non-routine operations in fiscal 2018, it appears that our efforts were effective. By type of injury, we were unable to completely eliminate accidents related to becoming caught or entangled in machinery. Concerning this issue, we will promote the leaflet of Precautions Concerning Becoming Caught or Entangled in Machinery, which we formulated internally, and implement further preventative measures.
*Significant Occupational Injuries:
“Significant Occupational Injuries(SOIs)” refer to occupational injuries that resulted in absence from work or death. SOIs also include lighter occupational injuries that, due to the potential danger in the cause of the injury, could have led to absence from work or death. SOIs do not include those injuries that are not directly related to operations.
Comparison of Occupational Injury Frequency between Mitsui Chemicals, the All Industries in Japan and the Japanese Chemical Industry
*Occupational injury frequency = Number of individuals killed or injured by occupational accidents x 1 million hours / Total working hours for all employees
*The figures for the all industries in Japan and for the Japanese chemical industry indicate the Days Away From Work Case (DAFWC) frequency. The Mitsui Chemicals figures represent the DAFWC frequency until the end of the first half of fiscal 2012, and the Significant Occupational Injury frequency from the second half of fiscal 2012.
