The Company conducts hazard identification and risk assessments for work activities across all operational processes. The severity and likelihood of potential incidents are evaluated to determine and prioritize risks. Risk assessments are reviewed annually or whenever there are changes in work processes, machinery, or technology, as well as following accidents or near-miss incidents, to ensure that control measures remain appropriate and aligned with changing working conditions.

To effectively identify and assess occupational health and safety risks in the workplace, the Company identifies and prioritizes risks and integrates risk management into its action plans and corporate objectives. This approach aims to control risks while supporting opportunities for the continuous improvement of the Company’s occupational health, safety and working environment management system.

The risk assessment process is as follows:

1). Classification of Work Activities and Areas

The Head of Section / Supervisor, together with department representatives, classifies the work under their responsibility, including relevant activities and work areas. The results are recorded in the designated Work Activities and Areas Classification Form.

2). Hazard Identification

Department representatives review the classified work activities and areas to identify potential hazards associated with each activity. The identified hazards are recorded in the Hazard Identification and Risk Assessment Form (Risk Assessment).

3). Risk Evaluation

Department representatives evaluate the identified hazards to determine the level of risk based on two key criteria: the severity of the hazard and the likelihood of occurrence. The results are recorded in the Hazard Identification and Risk Assessment Form (Risk Assessment).

a. Likelihood

b. Risk Impact

c. Opportunity Impact

The risk and opportunity levels are calculated as follows:

• Risk Exposure = Likelihood × Risk Impact
• Opportunity Level = Likelihood × Opportunity Impact

Risks and opportunities related to the Occupational Health and Safety Management System are evaluated according to the following risk classification matrix:

d. Risk Acceptance Criteria

4). Risk Management Based on Assessment Results

The results of the risk assessment are used to determine appropriate risk management actions, taking into consideration the nature of the risk, required investment, and expected benefits. The following risk treatment approaches are applied:

a. Avoid

Actions are taken to avoid activities or events that may give rise to risk. This approach is generally used when the risk is highly severe and cannot be reduced or managed to an acceptable level.

b. Share

All or part of the risk is shared with or transferred to an external party or organization to help assume the risk burden, such as outsourcing certain activities to external service providers.

c. Reduce

Control measures are implemented to reduce the likelihood of a risk event occurring or to minimize its potential impact to an acceptable level. Examples include developing a Contingency Plan, building organizational capabilities, and establishing appropriate operating procedures.

d. Accept

The remaining risk is considered to be within an acceptable level, and no additional action is required to further reduce its likelihood or impact. This approach is generally applied when the cost of additional risk control measures would outweigh the expected benefits.
