Abstract:
This study applies risk assessment and hazard analysis techniques to evaluate occupational and operational safety risks in a wood manufacturing process, using a sawmill located in Warri, Delta State, Nigeria as a case study. Despite the crucial role of sawmills in Nigeria's wood value chain, they remain prone to high-risk operations due to inadequate safety measures and obsolete machinery. The study adopted a mixed-method approach combining observation, interviews, and hazard identification checklists. Risk assessment was carried out using the Failure Mode and Effects Analysis (FMEA) and Risk Matrix models based on ISO 31000 standards. Findings revealed that mechanical hazards (40%), ergonomic hazards (25%), and noise exposure (20%) constituted the major risk categories. The overall risk priority numbers (RPN) ranged from 40 to 210, with unguarded cutting machines and poor wood handling practices ranked as "high-risk" activities. While workers demonstrated awareness of safety practices, compliance with personal protective equipment (PPE) usage was below 60%. The study recommends safety engineering controls, regular safety training, and compliance monitoring by regulatory bodies to reduce operational hazards in sawmill operations. The findings underscore the need for proactive occupational safety management in Nigeria's wood manufacturing industry.
