Implication

Case study uncovers key occupational hazards in power plant construction workers, highlighting the need for combined technical and organizational safety controls.

Key Points

To develop and evaluate a hybrid risk assessment methodology that links semi-quantitative risk perception with task-focused hazard analysis in power plant construction.
Surveyed 105 workers (response rate 75.0%) across eight construction activities and four occupational groups at a combined cycle power plant site.
Calculated likelihood and severity scores to construct 5 × 5 risk matrices and prioritization indices, followed by task-focused HAZOP modeling of high-risk activities.
Work at height ranked as the highest perceived risk activity across all worker groups, followed by lifting/load handling, chemicals/flammables, and electrical tasks.
Safety technicians provided significantly more conservative risk scores than general labor personnel, demonstrating role-dependent risk perception gaps.
HAZOP analysis identified primary vulnerabilities in organizational procedures, specifically permit-to-work systems, lockout/tagout protocols, fall protection, and exclusion-zone management.
