Occupational Health and Safety


We share a high value for safety and we pursue the highest level of safety by building high-quality systems and continuing activities.

ISO45001 certification

We have continued to obtain ISO 45001 certification (including its predecessor, OHSAS 18001), the international standard for occupational health and safety management for on-site construction work, and currently maintains the 2018 version.

ISO45001 certification

In order to provide a safe and healthy working environment for its workers, GX Solutions have established its own health and safety management system and is working to achieve a high level of health and safety standards and continuous improvement in accordance with the health and safety management system (Plan-Do-Check-Action).

Safety and health management (organization and process)

Our health and safety management system is divided into "Basic process" and "Project process."

Basic process

The SHEQ (Note) Management Depertment, a professional organization for safety and health management, is responsible for setting, planning, operating, and evaluating our safety and health management objectives, providing governance to each department and project, and providing support.
Through the creation of operational standards, diverse safety and health education programs, and the President's safety awards, we are working to raise the safety awareness of each employee and foster a culture of safety.

Project process

The Construction Department, which carries out safety management at construction sites, cooperates with the SHEQ Management Department and holds regular meetings to share information on each site. The meetings help maintain high safety standards on all projects.
In addition, HSSE managers (Health, Safety, Security and Environment) are assigned to the construction sites of each project. We will lead daily safety and health activities at construction sites, including advance consideration of safety measures based on risk assessment, on-site safety patrols, and safety instructions at morning meetings.

Safety statistics record

We have maintained a high safety record at both domestic and international construction sites. Using the industry's standard safety management indicators, TRIR (*01) and LTIR (*02), we have set a high level of "TRIR: 0.15 or less, LTIR: 0.03 or less" as our goal (*03). We continue to achieve this goal and in 2021 we achieved zero accidents (0 for both TRIR and LTIR) as a result of the various safety activities we implemented.

Trends in Safety Management Indicators (TRIR and LTIR) at Construction Sites
  • 01Total Recordable Incident Rate : Total Recordable Incident Rate: An index developed by the U.S. Occupational Safety and Health Administration (OSHA) to measure occupational injury safety. Number of Recordable Incidents per 200,000 total working hours
  • 02Lost Time Incident Rate: Number of Lost Time Incidents per 200,000 total working hours
  • 03Goal: Our goal is higher than the average safety performance of other companies in the manufacturing and construction industries in Japan and overseas

Activities to raise safety awareness

BBSO(Behavior Based Safety Observation)

At the construction site for each project, we conduct an all-hands BBSO to foster safety awareness, including the detection of unsafe conditions and behaviors, as well as good cases.

We also focus on disaster prevention activities by conducting STARRT (Safety Task Analysis Risk Reduction Talk: Identify and address prework anxiety conditions), LMRA (Last Minute Risk Assessment) and safety patrols.

Company training

We develop a "Project Safety Education System" for employee safety and health education, including "Safety Leadership Education" for PM (Project Manager) and SM (Site Manager), and operate an e-Learning education program that enables employees to acquire the necessary safety knowledge at each step to become a PM (Project Manager) or SM (Site Manager).
In addition, as part of the Project Safety Education System, the company conducts a monthly "safety e-drill" not only for project workers but also for all employees, including the executives and administrative departments. By repeating the course until they receive a perfect score, each employee continuously improves their safety knowledge and fosters safety awareness.

Safety activities at Mihara plant

At the Mihara plant, where we manufacture the vehicles and air brake systems, we strive to raise safety awareness as follows,

  • holding monthly safety conferences to share the month's safety theme for strengthening safety activities
  • reviewing safety work procedures and ensuring procedures are visual to prevent human errors
  • implementing daily TBM(*) to remind employees of safety work procedures on the day
  • providing mutual safety supervision by managers and workplace patrols
  • conducting greeting campaigns to promote communication, proposing improvements and reporting medical near-miss incidents
  • Tool Box Meeting : Workplace meeting
