Özet

This study provides a comprehensive evaluation of occupational health and safety (OHS) hazards, toxicological characteristics, and respiratory health risks associated with composite manufacturing and fiber-reinforced polymer (FRP/GRP) production environments. The research synthesizes official labor statistics, national academic theses, and international scientific literature to identify critical occupational exposure pathways and assess their potential effects on workers' health. Composite manufacturing processes, particularly open-mold applications, resin preparation, raw material mixing, lamination, and surface finishing, may expose workers to hazardous chemical substances, including volatile organic compounds (VOCs), styrene, organic solvents, and respirable particulate matter. Styrene exposure is of particular concern because airborne concentrations may exceed applicable occupational exposure limits, potentially contributing to oxidative DNA damage in peripheral blood lymphocytes, cytotoxic effects in buccal epithelial cells, and other adverse biological responses. In addition to chemical hazards, acoustic assessments indicate that noise levels in certain production areas may exceed the upper exposure action value of 85 dB(A), increasing the risk of occupational hearing impairment. Respiratory health assessments further highlight the association between prolonged exposure to respirable dust, glass and carbon fiber particles, and chemical aerosols with reduced pulmonary function, airway irritation, and chronic respiratory conditions, including bronchitis. Based on these findings, this study proposes an integrated risk mitigation framework structured around the hierarchy of controls. Recommended measures include transitioning from open-mold to closed-mold manufacturing technologies, implementing effective local exhaust ventilation (LEV) systems, improving process automation, conducting regular workplace exposure monitoring, and strengthening occupational health surveillance. Administrative measures, including appropriate work organization and exposure-time management, should complement engineering controls. Finally, certified personal protective equipment (PPE), including EN 140-compliant half-mask respirators with appropriately selected ABEK1-P2 filters, should be used as a supplementary protective measure to minimize residual occupational risks and promote safer, healthier, and more sustainable composite manufacturing environments.
