Safety and Health Management in Indonesia

PT Komatsu Indonesia Tbk (KI) manufactures numerous products such as hydraulic excavators and dump trucks. KI implements various types of safety activities referring to the ones carried out at Osaka plant and Ibaraki plant which are the mother plants for KI. Placing special emphasis on undertaking risk assessments, KI has been working on safety improvement activities from both top-down and bottom-up approaches.

Since the introduction of the risk assessment activities in 2009, the methodology of priority scheme on risk management against industrial accidents has been nurtured and shared by all employees at KI. By holding monthly safety meetings, the entire company focuses on risk assessment activities such as prediction of potential risks, judgement of the risk level, risk control actions, effectiveness measurement, and further standardization. Numbers of safety training sessions at the “Safety Training Hall ” for anticipating potential dangers also foster the establishment of risk assessment methods at KI.

In 2012, Safety & Health Administration Dept. of Komatsu head office visited KI and advised to work on the OHSAS18001 certification. As a result of proactive activities, KI succeeded in gaining the OHSAS18001 certification in February 2014. In recent years, KI has been developing risk assessment methodologies for its group companies and suppliers in Indonesia. Also, in June 2016, KI achieved long hours of operation without industrial accidents, and received a commendation from the Komatsu’s head office.

To obtain the OHSAS18001 certification, KI asked for support from the University of Indonesia which has a reputation in the fields of medical and health management in the Southeast Asia area. They have achieved progress not only in their safety management system, but also in the management of health risks for own employees. KI has formulated a medical checkup program related to health risks which is being used for early detection and swift treatment of various diseases such as life-style related diseases.
