Rate of accident per 1,000 employees in one year (absence of 4 days or longer)

Results for 2021	Goal for 2022
2.92	0.7以下

*It is the number of workers who get injured or die per 1,000 workers per year, and can be expressed by the following equation:

Rate of accident per 1,000 employees in one year	＝	Number of workers who get injured or die in a year	× 1,000
		Average number of workers in a year

*1 Period: From January 1 to December 31
*2 Including the subcontractors of the Toho Titanium Group

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.
