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

Results for 2023	Goal for 2024
2.4	0.0

*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 2023 and future countermeasures

Regarding safety performance in 2023, there were 4 industrial accidents that forced workers to take days off and 11 industrial accidents that did not require workers to take days off.
Regarding industrial accidents that force workers to take days off, we were not able to keep the number of them zero from 2021, and recognized the existence of issues on which we should reflect.
Regarding industrial accidents that do not require workers to take days off, we were not able to attain the goal of reducing the number of them by 50% year on year to 8 or less, but it is decreasing year by year, and it decreased by 2 from the previous year. We think that this is an outcome of our efforts to foster employees’ awareness of safety.
It was found through the statistical analysis of industrial accidents in 2023 that such accidents often occur to workers with less than 3 years of experience like in 2022. The eye part was damaged for half of the victims, and 4 workers suffered from heatstroke in the summer. Regarding the number of cases of each kind of accidents, the cases of contact with a harmful or high/low-temperature object decreased 50% from the previous year, but the cases of recoil and tipping over increased. This indicates that we need to take a broad range of safety measures.
To avoid these accidents, our corporate group will strive to improve the quality of education with IT-based educational programs (for new employees, including mid-career workers, for improving the skills of foremen, and for visits to new work sites) and increase educational opportunities to improve the awareness of safety at each workplace and eradicate industrial accidents.

Fatal accidents

We aim to achieve zero fatal accidents in 2024.
