The EW Group has also set a target of “zero workplace accidents” to create a safe working environment, enhance the quality of work life for employees, business partners, and contractors, and ensure compliance with relevant laws and standards. This includes assessing occupational health and safety risks in existing operational processes and potential future projects, in order to plan preventive measures, control strategies, and mitigation guidelines to reduce potential impacts. Furthermore, managing occupational health, safety, and the working environment is part of a sustainability management policy overseen by the Governance and Sustainability Committee to achieve the goal of zero work-related accidents.
In 2025, the EW Group reviewed its Work Instruction documents to improve usability, and revised performance record documents to align with actual operations and relevant legal requirements.
In 2025, there was 1 workplace accident, resulting in 1 employee injury. The incident occurred while the employee was performing duties by accompanying senior management on a site visit.
