Measures on traffic safety

Because of the Company’s location in western Shizuoka Prefecture, many employees commute to work in their own vehicles. The Company takes the following measures to promote safe driving and prevent accidents.

  • Employees are reminded at the workplace about safe driving.
  • The Traffic Subcommittee provides traffic guidance.
  • Employees who have suffered traffic accidents are interviewed.
  • A designated-workplace system is in effect. In this system, workplaces with high traffic-accident rates are identified and activities are intensified at those locations. For example, traffic observers provide guidance, safety declarations are issued, traffic KYT (hazard-prediction training) is conducted monthly and seminars are provided by advisors and persons responsible for traffic.
