Workplace Accidents

KIOXIA Group in Japan strives to minimize the number of workplace accidents and monitor any occurrences. We use the “frequency of injuries resulting in lost working days” as an indicator for these efforts. In FY2021, the frequency rate was 0.30, which was below the average rate of 0.52 in the electric machinery and equipment manufacturing industries.

KIOXIA Group in Japan will continue to implement further measures to prevent workplace accidents. In particular, we will prioritize the reduction of hazardous risks that could lead to illness or serious injury and conduct risk assessments of all workplaces and tasks. Leveraging the results of these assessments, we identify current and potential risks, review work methods, and systematically deploy any necessary measures to minimize and eliminate such risks. Furthermore, we are improving facilities and provide comprehensive OHS training for all employees.
