Analysis of accidents in 2021 and future countermeasures
16 industrial accidents (accidents resulting in no absence of the following day and more serious ones) occurred in 2021, significantly exceeding the 8 accidents in 2020. Regarding the classification of the 16 accidents, there were 6 burns/chemical burns, 4 accidents caused by unnatural motion/reaction and 6 other accidents. Furthermore, 9 of the 16 accidents occurred during infrequent operation and 7 out of these were caused by maintenance work.
In 2022, we will engage in the prevention of accidents with the following important measures: (1) Sure risk assessment and promotion of risk reduction, (2) prohibition of the handling of heavy objects by a single worker and (3) reinforcement of safety education.
