Based on the principle that ensuring the safety of employees is the first priority in all business operations, these rules are guiding our proactive efforts to ensure safety and prevent occupational injuries, promote health maintenance and form comfortable workplace environments.
Beginning in 2020, contractor employees at plants and research laboratories whose presence results in mixed operations in the same location have been included in the scope of collation. The Chugai Group is engaged in safety and health management activities to ensure that not only its own employees, but those of our partner companies, can work safely and in good health.
There were 22 occupational injuries in 2022. None of them required lost worktime, and there were no accidents resulting in lost worktime. Additionally, there were no occupational illnesses or fatal accidents.
Change in Lost-worktime injury frequency rate
Change in Occupational incidence severity
- *1 Beginning in 2020, contractor employees at plants and research laboratories whose presence results in mixed operations in the same location have been included in the scope of collation.
|Number of accidents||Frequency rate*2|
|Total lost-workdays||Severity rate*3|
- *2 Number of people injured or killed in occupational accidents per 1 million work hours (excluding accidents during commuting), showing the frequency of occurrence
Injury frequency rate = number of people injured or killed in occupational accidents / total number of actual working hours x 1,000,000
- *3 Number of days of work lost to occupational accidents (excluding accidents during commuting) per 1,000 work hours, showing the severity of the accident
Occupational incidence severity = number of workdays lost / total number of actual working hours x 1,000
- *4 When the number of actually worked hours of temporary workers is unknown, it is estimated by multiplying the number of such workers as of December 1 of the relevant year x 7.75 hours/day x working days.
