Occupational Safety and Health Management

WNC headquarters and main manufacturing bases have introduced the ISO 45001 occupational safety and health management system and passed third-party verification with regards to this. In 2022, no major occupational accidents occurred at any sites.

Risk Identification

In order to lessen the impact on WNC of occupational safety and health risks, every department annually carries out risk identification, evaluates risk levels through matrix analysis (likelihood, severity, frequency), proposes corresponding control measures and objectives for high-risk operations, and conducts monthly tracking (such as: when there are changes in operations, technologies, engineering, operations/design specifications; injury events with more than one day of incapacity; repeated occurrence of false alarm incidents; hidden danger notification).

Hazard identification

The responsible department conducts an inventory of activities, products, services, etc. within its control that may cause personal injury, property damage, or environmental impact.

Risk evaluation

Risk level is evaluated through matrix analysis of operations exposure frequency, probability of occurrence, and severity of consequences.

Control measures

Improvement plans are proposed for improvement items that eliminate hazards or reduce occupational safety and health risks within a department, meaning the objective of continuous risk reduction has been achieved.

Review of effectiveness

Identify residual risks after control measures are in place, conduct monitoring and measurement to ensure the effectiveness of controls.

Accident Investigation

In Taiwan, to fully understand the process by which near misses, abnormalities, injuries, and major accidents occur and to prevent their reoccurrence, the company performs accident investigation and analysis in accordance with an Accident Investigation Management Procedure and has formulated measures to prevent the re-occurrence of incidents. Inspection is conducted across all sites. At the same time, FMEA (Failure Mode and Effect Analysis) and domino analysis methods are used to conduct a more in-depth review and discussion of the real causes of accidents and improve processes and safety standards and standardize specifications, as well as strengthen fool-proofing mechanisms.


To enhance accident investigation efficiency, explore root causes, and prevent recurrence, an accident investigation approval system has been implemented. System architecture for the Taiwan plant has been established in 2022, and the system is expected to be operational in 2023.

Execution of measures in parallel
Conduct inventories of plants and implement prevention measures in parallel to achieve early prevention

Friendly Workplace

WNC continues to implement health care measures and health promotion activities to create a friendly and healthy workplace.
WNC sites employ nurses with past clinical experience in internal medicine, surgery, obstetrics and gynecology, pediatrics, and intensive care medicine. The facility nurses compile analyses of employees’ health issues, perform personal health hierarchical management, and plan annual health care and promotion activities accordingly to assist staff in enhancing their health awareness.

Contractor Management

WNC conducts contractor review annually to evaluate contractors’ safety and health management capabilities. Guidance or replacement of contractors is executed according to review results. Starting from 2020, construction evaluations will be added for new contractors, and the contractor evaluation items, scoring standards and calculation formulas will be more clearly and specifically defined to ensure the standardization of evaluations and reduce manual calculations errors. In addition, to strengthen the management of hazardous operations of contractors, a checklist has been drawn up for higher-risk operations including hot work, roofing, hanging, and restricted operations, to ensure that contractors follow the safety standards before, during, and after operations. In 2022, a total of 16 new suppliers in the factory construction category were evaluated.
