Occupational Safety and Health

Occupational Safety and Health is a core component in Komatsu's business operations. In line with this commitment, Komatsu thus enhances safety at the workplace for our employees and business partners.

The president announced the “Komatsu Health Declaration” in June 2014 to effectively promote this goal.

The Diversity Task Team, which was established in the Second Health Development Plan, will continue its activities by setting the goal of holding health seminars for women at all Komatsu bases by the end of FY2021.

Awareness Raising on HIV/AIDS Issues at Komatsu South Africa (Pty) Ltd.

At Komatsu South Africa, we provided an opportunity for our employees to learn about HIV/AIDS as part of the Wellness Day events. The objective of this initiative is to increase general awareness of health, not only by learning basic knowledge on HIV/AIDS, but also by receiving medical check-ups and obtaining knowledge on healthy life styles.

On-site Survey of Malaria in Senegal and Cote d'Ivoire

To prevent Komatsu resident officers and local employees from succumbing to malaria and to improve our response to infection, we inspected living and work environments in the community and visited medical agencies, etc. in August 2019, accompanied by Komatsu industrial doctors. Malaria is normal in these countries, and it is difficult to stop it completely. However, to minimize the risk of infection as much as possible, we have defined preventive measures and our responses to inflection more clearly.
